     Before:  Williams, Ginsburg and Sentelle, Circuit Judges.

     Opinion for the Court filed by Circuit Judge Sentelle.

     Sentelle, Circuit Judge:  In Indiana Michigan Power Co. 
v. Department of Energy, 88 F.3d 1272 (D.C. Cir. 1996), we 
held that the Nuclear Waste Policy Act ("NWPA") imposes 
on the Department of Energy ("DOE") an unconditional 
obligation to begin disposing of high-level radioactive waste 



and spent nuclear fuel (collectively, "SNF") by January 31, 
1998.  After we issued our decision, DOE nonetheless in-
formed various utilities and state commissions ("petitioners") 
that it would not accept the SNF for disposal by the 1998 
deadline.  Petitioners now seek a writ of mandamus requiring 
DOE to comply with Indiana Michigan and begin disposing 
of the SNF by the statutory deadline.  We hold that the 
Standard Contract between DOE and the utilities provides a 
potentially adequate remedy if DOE fails to fulfill its obli-
gations by the deadline, and thus do not grant in full the writ 
requested by petitioners.  We do agree, however, that DOE's 
current approach toward contractual remedies is inconsistent 
with the NWPA and with our prior decision in Indiana 
Michigan.  We thus grant the petition in part, and issue a 
writ of mandamus precluding DOE from advancing any con-
struction of the Standard Contract that would excuse its 
delinquency on the ground that it has not yet established a 
permanent repository or an interim storage program.

                                I. Background


     In the NWPA, Congress, confronting the "national prob-
lem" posed by the accumulation of spent nuclear fuel and 
radioactive waste produced by various domestic sources, 42 
U.S.C. s 10131(a)(2), created a scheme whereby the federal 
government would have the responsibility to provide for the 
permanent disposal of the SNF, and the costs of such disposal 
would be borne by the owners and generators of the waste 
and spent fuel.  42 U.S.C. s 10131(a)(4).  The plan provided 
that the owners and generators of the SNF would have the 
primary responsibility to provide and pay for its interim 
storage until the Secretary of Energy accepts the material "in 
accordance with the provisions of this chapter."  42 U.S.C. 
s 10131(a)(5).

     As part of this regulatory program, Congress authorized 
the Secretary to enter into contracts with the owners and 
generators for the acceptance, transportation, and ultimate 
disposal of the SNF.  42 U.S.C. s 10222(a)(1).  Congress left 
open many of the terms of the contracts, but specifically 



dictated, inter alia, the deadline by which DOE must begin 
disposing of the SNF.  In the language of the statute, the 
"[c]ontracts entered into under this section shall provide that 
... in return for the payment of fees established by this 
section, the Secretary, beginning not later than January 31, 
1998, will dispose of the high-level radioactive waste or spent 
nuclear fuel involved as provided in this subchapter."  42 
U.S.C. s 10222(a)(5)(B).  "Payment of fees" referred to hefty 
contributions into a so-called Nuclear Waste Fund by owners 
and generators of the SNF.

     In accordance with the NWPA, DOE adopted the final 
Standard Contract after notice and comment.  The language 
of the Standard Contract is slightly different than that of the 
statute, but does include the requirement that disposal begin 
by January 31, 1998:  "[t]he services to be provided by DOE 
under this contract shall begin, after commencement of facili-
ty operations, not later than January 31, 1998 and shall 
continue until such time as all SNF and/or HLW [high-level 
radioactive waste] from the civilian nuclear power reactors 
... has been disposed of."  10 C.F.R. s 961.11, Art. II (1996).

     In 1993, various utilities and state agencies became con-
cerned about DOE's ability to meet the 1998 deadline, and 
thus asked the Department to address how it would go about 
performing its responsibilities.  The Department, apparently 
anticipating that it would not be ready to take the SNF by 
the deadline, took the position that it did not have a clear 
legal obligation to accept the SNF absent an operational 
repository or other facility.  In its Final Interpretation of 
Nuclear Waste Acceptance Issues, issued in 1995, DOE an-
nounced that it "does not have an unconditional statutory or 
contractual obligation to accept high level waste and spent 
nuclear fuel beginning January 31, 1998 in the absence of a 
repository or interim storage facility constructed under the 
[NWPA]."  60 Fed. Reg. 21,793-94.  The Department also 
took the position that "it lacks statutory authority under the 
Act to provide interim storage."  60 Fed. Reg. at 21,794.

     The utilities and the states promptly filed petitions for 
review.  The question before us in Indiana Michigan was 



whether the legal obligation of DOE to accept SNF by 
January 31, 1998, was conditioned on the presence of an 
operational repository or interim storage facility.  Reviewing 
DOE's construction of the NWPA under the two-step analysis 
of Chevron U.S.A. Inc. v. Natural Resources Defense Coun-
cil, 467 U.S. 837 (1984), we concluded that DOE's interpreta-
tion was contrary to the unambiguously expressed intent of 
Congress.  We reached this conclusion after analyzing the 
plain language of the statute, which mandates that DOE 
assume a contractual obligation to start disposing of the SNF 
by January 31, 1998.  We took special care to emphasize the 
reciprocal nature of the obligations.  DOE's duty to dispose 
of the SNF in a timely manner is "in return for" the payment 
of fees into the Nuclear Waste Fund. 42 U.S.C. 
s 10222(a)(5)(B).  We held that DOE's obligation to meet the 
1998 deadline is "without qualification or condition," and 
identified DOE's duty to "perform its part of the contractual 
bargain."  88 F.3d at 1273.  We therefore remanded the 
matter to DOE for "further proceedings consistent with" our 
opinion.  Id. at 1277.  DOE neither sought rehearing of that 
decision nor petitioned the Supreme Court for further review.

     After issuing our decision in Indiana Michigan, we would 
have expected that the Department would proceed as if it had 
just been told that it had an unconditional obligation to take 
the nuclear materials by the January 31, 1998, deadline.  Not 
so.  Quite to the contrary, the Department informed the 
utilities and the states that it would be unable to comply with 
the statutory deadline that this court had just reaffirmed.  In 
late 1996, the utilities and the states initiated discussions with 
DOE and asked about the procedure and schedule that the 
Department would follow to comply with the court's decision.  
DOE responded to the utilities by announcing that it "will be 
unable to begin acceptance of spent nuclear fuel for disposal 
in a repository or interim storage facility by January 31, 
1998."  Utility Petitioners' Pet. at Tab 1;  see also Tab 2.  
The Department recognized that the delay would affect "large 
number[s]" of contract holders, but nonetheless expressed 
"uncertainty as to when DOE will be able to begin spent fuel 
acceptance."  Id.  The letter ended by cordially inviting "the 



views of all contract holders on how the delay can best be 
accommodated."  Id.

     In a similar letter to the states, DOE wrote that it "under-
stands that states are concerned about the Department's 
delay," and expressed an interest in talking with the states 
about how to mitigate the harm caused by the delay.  State 
Petitioners' Pet., Att. D.  DOE's letter also revealed one of 
its asserted reasons for the delay:  "The Administration con-
tinues to believe that interim storage siting should not pro-
ceed until the Department has the benefit of the information 
resulting from the Yucca Mountain Project Viability Assess-
ment."  Id.  By the Department's own estimates, this Yucca 
Mountain facility will not be operational until the year 2010.  
Exhibits to Resp. Response, Tab 6, at 8.

     On January 31, 1997, the utilities and state agencies sepa-
rately petitioned for a writ of mandamus, seeking to compel 
DOE to comply with Indiana Michigan and begin disposal of 
the nuclear materials by January 31, 1998.  Petitioners also 
requested that their payments to the Nuclear Waste Fund be 
placed in escrow unless and until DOE meets its obligations 
to dispose of SNF, and asked that the court prohibit DOE 
from taking any punitive action toward those who suspend 
payments to the Fund.

     On June 3, 1997, DOE responded to comments submitted 
by contract holders regarding the anticipated delay.  The 
Department began by recognizing that "Section 302 [of the 
NWPA] specifies that the contracts shall provide for the 
Department to begin to dispose of spent fuel not later than 
January 31, 1998."  Exhibits to Resp. Response, Tab 6, at 4. 
DOE then expressed its belief that "the Standard Contract 
adopted by the Department pursuant to Section 302 and 
entered into by the contract holders specifies the available 
remedies in the event the Department is unable to meet the 
January 31, 1998 date."  Id.  Under Article IX of the con-
tract, the Department asserted, the Department was "not 
obligated to provide a financial remedy for the delay," be-
cause the delay, in the Department's estimation, was "un-
avoidable."  Id. at 2.  After conceding that the delay may 



result in "hardship" to contract holders, DOE expressed its 
willingness "to consider amendments to individual contracts 
that would mitigate the impacts of the delay particular con-
tract holders will experience in the acceptance of their spent 
fuel."  Id.

                                II. Discussion


     Petitioners assert that a writ of mandamus is necessary to 
force DOE to comply with Indiana Michigan and begin 
acceptance of the SNF by the 1998 deadline.  Their argument 
rests on our prior conclusion that "section 302(a)(5)(B) [of the 
NWPA] creates an obligation in DOE, reciprocal to the 
utilities' obligation to pay, to start disposing of the SNF no 
later than January 31, 1998."  88 F.3d at 1277.  DOE has not 
only failed to undertake "further proceedings consistent with" 
the court's opinion, petitioners argue, but has informed them 
of its plans to default on its obligations.  Petitioners draw 
special attention to the fact that the Department currently 
accepts SNF from 41 foreign countries, from which they 
conclude that DOE is not unable but is simply unwilling to 
meet the 1998 deadline.  They submit that a writ of manda-
mus is an appropriate remedy for the Department's refusal to 
comply with Indiana Michigan and perform its duties by the 
deadline set by Congress.1

     We start our consideration of the petition with the observa-
tion that "[t]he remedy of mandamus is a drastic one, to be 
invoked only in extraordinary situations."  Allied Chemical 
Corp. v. Daiflon, Inc., 449 U.S. 33, 34 (1980).  Mandamus is 
proper only if "(1) the plaintiff has a clear right to relief;  (2) 
the defendant has a clear duty to act;  and (3) there is no 
other adequate remedy available to plaintiff."  Council of and 
for the Blind of Delaware County Valley v. Regan, 709 F.2d 

__________
     1  The state petitioners also contend that a writ of mandamus is 
warranted, wholly apart from our decision in Indiana Michigan, 
under Telecommunications Research & Action Center v. F.C.C., 750 
F.2d 70 (D.C. Cir. 1984) ("TRAC").  State Petitioners' Pet. at 9-12.  
Because we issue a writ of mandamus to effectuate our decision in 
Indiana Michigan, we decline to reach the additional question of 
whether issuance of the writ would have been proper under TRAC.



1521, 1533 (D.C. Cir. 1983) (en banc).  The party seeking 
mandamus has the burden of showing that "its right to 
issuance of the writ is clear and indisputable."  Gulfstream 
Aerospace Corp. v. Mayacamas Corp., 485 U.S. 271, 289 
(1988) (internal quotations and citations omitted).

     Petitioners have established that they have a clear right to 
relief, and thus have satisfied the first requirement for a writ 
of mandamus.  As we explained in Indiana Michigan, the 
NWPA requires DOE, "in return for the payment of fees," to 
begin disposing of the materials "not later than January 31, 
1998."  42 U.S.C. s 10222(a)(5)(B).  We specifically noted 
that the payment of fees into the Nuclear Waste Fund is the 
"only limitation placed on the Secretary's duties" found in the 
text of the statute.  88 F.3d at 1276.  The owners and 
generators have dutifully complied with the NWPA, pouring 
billions of dollars of payments into the Fund with the expecta-
tion that DOE would live up to its end of the bargain.  The 
Department, on the other hand, has tersely informed the 
parties that it "will be unable to begin acceptance of spent 
nuclear fuel for disposal in a repository or interim storage 
facility by January 31, 1998."  Utility Petitioners' Pet. at Tab 
1.  Petitioners' full compliance with the requirements of the 
NWPA, taken in conjunction with DOE's refusal to perform 
its reciprocal duties, compels the conclusion that petitioners 
have established a clear right to relief in this case.

     The second requirement is also satisfied.  DOE's duty to 
act could hardly be more clear.  DOE argued in Indiana 
Michigan that its obligations under the NWPA were contin-
gent on the existence of a repository or interim storage 
facility.  We held that DOE's interpretation was inconsistent 
with the text of the NWPA, which clearly demonstrates a 
congressional intent that the Department assume a contractu-
al obligation to perform by the 1998 deadline, "without qualifi-
cation or condition."  88 F.3d at 1276.  DOE's duty to take 
the materials by the 1998 deadline is also an integral part of 
the Standard Contract, which provides that the Department 
"shall begin" disposing of the SNF by January 31, 1998.  10 
C.F.R. s 961.11, Art. II.  The contractual obligations created 
consistently with the statutory contemplation leave no room 



for DOE to argue that it does not have a clear duty to take 
the SNF from the owners and generators by the deadline 
imposed by Congress.

     Although petitioners have a clear right to relief, and the 
Department has a clear duty to act, we decline to issue the 
broad writ of mandamus sought by petitioners because they 
are presented with another potentially adequate remedy.  
Although the statute does not prescribe a particular remedy 
in the event that the Department fails to perform on time, the 
Standard Contract does provide a scheme for dealing with 
delayed performance.  10 C.F.R. s 961.11, Art. IX.  Specifi-
cally, Article IX of the Standard Contract outlines how the 
parties are to proceed if one party is unable to fulfill its 
obligations in a timely manner.  Under Article IX, unavoid-
able delays are to be treated differently than avoidable de-
lays.  A failure to perform is considered "unavoidable" only if 
such failure "arises out of causes beyond the control and 
without the fault or negligence of the party failing to per-
form."  Id. at Art. IX.A.  If a party's delay is determined to 
be unavoidable, that party is not liable for damages caused by 
the failure to perform in a timely manner.  Id.  An avoidable 
delay, in contrast, is caused by "circumstances within the 
reasonable control" of the delinquent party.  Id. at Art. IX.B.  
If a party's delay is avoidable, the charges and schedules in 
the contract must be equitably adjusted to reflect additional 
costs incurred by the other party.  Id.  The contract also 
provides a mechanism for resolving disputes of fact that the 
parties may encounter along the way.  See id. at Art. XVI.

     Petitioners have not convinced us that this contractual 
scheme is inadequate to deal with DOE's anticipated delay in 
accepting the SNF.  Petitioners have suggested that the 
contractual processes are inadequate, claiming that they will 
"suffer additional billions of dollars in additional costs if DOE 
fails to meet its January 1998 obligation," Utility Petitioners' 
Pet. at 4, and that they will not be able to recover these costs 
in the contract proceedings because the Department is excus-
ing its own default.  See Utility Petitioners' Reply at 2.  Such 
costs may in fact ensue if DOE fails to perform on time, but 
there is no reason to believe that these additional expenses 



will not be taken into account if the contractual processes 
operate as Congress intended.  See infra at 11-13.  Accord-
ingly, we conclude that petitioners must pursue the remedies 
provided in the Standard Contract in the event that DOE 
does not perform its duty to dispose of the SNF by January 
31, 1998.  This conclusion, we should note, comports with our 
decision in Indiana Michigan.  Even though we did not enter 
a remedy at that time, we suggested that the provisions of 
the Standard Contract would determine the appropriate rem-
edy for the Department's failure to perform its obligations.  
88 F.3d at 1277.

     A writ of mandamus is required, however, to compel DOE 
to comply with our prior mandate in Indiana Michigan.  See 
Office of Consumers' Counsel v. FERC, 826 F.2d 1136, 1140 
("A federal appellate court has the authority, through the 
process of mandamus, to correct any misconception of its 
mandate by a lower court or administrative agency subject to 
its authority.");  see also Potomac Electric Power Co. v. 
Interstate Commerce Comm., 702 F.2d 1026, 1032 (D.C. Cir. 
1983).  We held in Indiana Michigan that the NWPA impos-
es an unconditional obligation, memorialized in the Standard 
Contract, to begin disposing of the materials by January 31, 
1998.  We rejected the Department's attempt to water-down 
its obligations, finding that DOE's interpretation would "de-
stroy[ ] the quid pro quo created by Congress" and would 
mean that the payment of fees into the Nuclear Waste Fund 
"was for nothing."  88 F.3d at 1276.  To effectuate DOE's 
duty, as we recognized in Indiana Michigan, petitioners must 
be able to enforce the terms of the contract in a meaningful 
way.  Petitioners' ability to enforce the contract would be 
frustrated if DOE were allowed to operate under a construc-
tion of the contract inconsistent with our prior conclusion that 
the NWPA imposes an obligation on DOE "without qualifica-
tion or condition."  Id.

     Viewed in this light, DOE's current approach toward con-
tractual remedies violates our directives in Indiana Michi-
gan.  As explained above, the Department has endeavored to 
proceed according to Article IX of the Standard Contract, by 
first informing the parties of its anticipated delay, and then 



evaluating whether its own delay is "unavoidable."  Article IX 
describes an unavoidable delay as a party's "failure to per-
form its obligations ... aris[ing] out of causes beyond the 
control and without the fault or negligence of the party failing 
to perform."  10 C.F.R. s 961.11, Art. IX.A.  The contract 
goes on to list a few examples of circumstances "beyond the 
reasonable control" of the delayed party:  "acts of God, or of 
the public enemy, acts of Government in either its sovereign 
or contractual capacity, fires, floods, epidemics, quarantine 
restrictions, strikes, freight embargoes and unusually severe 
weather."  Id.  The Contracting Officer isolated six factors 
that, taken together, supposedly support the conclusion that 
DOE experienced an unavoidable delay in this case:  technical 
problems;  regulatory delays;  roadblocks to implementation 
of interim or monitored retrievable storage;  funding restric-
tions;  litigation delays;  and consultation requirements.  Ex-
hibits to Resp. Response, Tab 6.  Reaching the preliminary 
conclusion that the delay was unavoidable, the Department's 
Contracting Officer let DOE off the hook for monetary dam-
ages.

     The most glaring problem with DOE's position is that it is 
answering the wrong question:  it is attempting to explain 
why it will not have a "state-of-the-art, deep geologic facility 
for the permanent disposal of the Nation's spent nuclear fuel 
and high-level waste" ready by 1998.  Id.  Put another way, 
DOE's position is that its delayed performance is unavoidable 
because it does not have an operational repository, and does 
not have the authority to provide storage in the interim.  
DOE is simply recycling the arguments rejected by this court 
in Indiana Michigan.  DOE unsuccessfully argued in that 
case that it does not have an obligation to take the SNF in 
the absence of an operational repository or other facility;  
here, DOE recycles that same argument in the slightly differ-
ent form that it does not have responsibility for the costs 
resulting from its failure to perform that duty because it does 
not have an operational repository or other facility.  As we 
pointed out in Indiana Michigan, the NWPA directs DOE to 
undertake the duty to begin taking the SNF by January 31, 
1998, whether or not it has a repository or interim storage 
facility.  DOE cannot now render its obligation contingent, 



and free itself of the costs caused by its delay, by advancing 
the same failed position that we rejected before.

     Given DOE's repeated attempts to excuse its delay on the 
ground that it lacks an operational repository or interim 
storage facility, we find it appropriate to issue a writ of 
mandamus to correct the Department's misapprehension of 
our prior ruling.  Accordingly, we order DOE to proceed with 
contractual remedies in a manner consistent with NWPA's 
command that it undertake an unconditional obligation to 
begin disposal of the SNF by January 31, 1998.  More 
specifically, we preclude DOE from concluding that its delay 
is unavoidable on the ground that it has not yet prepared a 
permanent repository or that it has no authority to provide 
storage in the interim.

     This necessarily means, of course, that DOE not implement 
any interpretation of the Standard Contract that excuses its 
failure to perform on the grounds of "acts of Government in 
either its sovereign or contractual capacity."  10 C.F.R. 
s 961.11, Art. IX.A.  We held in Indiana Michigan that the 
NWPA imposes an unconditional duty on DOE to take the 
materials by 1998.  Congress, in other words, directed DOE 
to assume an unqualified obligation to take the materials by 
the statutory deadline.  Under the Department's interpreta-
tion of the governing contractual provisions, however, the 
government can always absolve itself from bearing the costs 
of its delay if the delay is caused by the government's own 
acts.  This cannot be a valid interpretation, as it would allow 
the Executive Branch to void an unequivocal obligation im-
posed by Congress.  DOE has no authority to adopt a 
contract that violates the directives of Congress, just as it 
cannot implement interpretations of the contract that contra-
vene this court's prior ruling.  We hold that this provision in 
the Standard Contract, insofar as it is applied to DOE's 
failure to perform by 1998, is inconsistent with DOE's statu-
tory obligation to assume an unconditional duty.

                               III. Conclusion


     In conclusion, we do not grant petitioners' broad request 
for a writ of mandamus because we conclude that the remedi-



al scheme of the Standard Contract offers a potentially 
adequate remedy.  We do, however, grant the petition in part 
because DOE has not abided by our prior conclusion that the 
NWPA imposes an unconditional obligation on the Depart-
ment to begin disposal of the SNF by January 31, 1998.  We 
therefore issue a writ of mandamus precluding DOE from 
excusing its own delay on the grounds that it has not yet 
prepared a permanent repository or interim storage facility.  
We retain jurisdiction over this case pending compliance with 
the mandate issued herewith.
