SUBJECT:

STATUS OF-POWER ACTOR DECOMMISSIONING COST ACTIVITIES I

l This memorandum provides information to the Commission on the status of rulemaking activities related to power reactor decommissioning cost issues, and is related to a Commission request, SRM dated July 14, 1993, for information on costs associated with " green field" and spent fuel mTnagement.

)

il As part of the updated decommissioning cost studies published in drsft NUREG/CR-5884 (PWR)'and draft NUREG/CR-6174 (BWR), PNL performed a limited

-l analysis of the spent fuel management and storage costs. Based on these analyses, the annual operating expense to maintain the spent fuel in:the pool on an-annual basis was estimated to be $4.1 million for the PWR and $5.5 million for the BWR, If the PWR licensee used-in the study were to decide to construct an ISFSI,-the estimated' capital cost would be $40.3 million with an annual operating expense of $2.0 million. The cost to decommission the ISFSI was estimated to be $4.0 million. The capital cost to construct an ISFSI for the BWR was estimated to.be $28.7 million because fewer concrete casks are required to. store the spent fuel. The annual operating expense for the ISFSI.

was estimated to be $2.1 million. The cost to decommission the ISFSI was estimated to be $2.9 million.

In response to the Commission's request, the staff contracted with PNL to i

evaluate the costs, over and above those needed to meet NRC radiological licensee termination requirements,' to also restore the reference PWR and BWR sites:(namely Trojan (PWR) and WNP-2 (BWR)) to a " green field" status. -The j

1

incremental cost estimates to restore the site to a " green field" status were i

approximately $3B.1 million dollars for the reference PWR and 548.2 million for the reference BWR. Based on the current revised estimates that PNL has

' prepared for decommissioning LWR's, the site restoration estimates would be approximately 30 percent ori ess of the cost to decommission the facility.

l The results of the BWR evaluation were included in NUREG/CR-6174 when it was released for public commert. Since NUREG/CR-5884 was released for comment

prior to conducting this evaluation, the results of the PWR evaluation will' be J

-noticed for. public commentJ separately.

lt should be emphasized that the cost estimates discussed above may not be typical or representative of the majority of licensed power reactors.

-The Commissioners 2

As a result, costs having substantial plant-specific components, the restoration to " green field" status for example, may not be representative of

{_

the majority of licensed power reactors.

After resolution of public comments on each of these studies, the staff plans l

to use the information obtained to determine if additional rulemaking is d

needed on power reactor decommissioning funding. ~ Based on the Commission's l

SRM dated July 14, 1993, the staff will consider ooth the amount of funding l

needed, and the use of alternatives, such as a parametric approach Lu determine funding requirements, to the current methodology. This rulemaking

~

will be provided to the Commission by March 1995.
