Dear Senator Sasser:

I am responding to the March 31, 1987 letter from you and Senator Gore concerning the need for the Department of Energy's (DOE) MonitoredofRetrievable in the provisions the NuclearStorage Waste Policy (MRS)Act facility (as contained NWPA). As your letter states, the NWPA requires DOE to consult with the Nuclear Regulatory Commission (NRC) and to submit NRC comments on the MRS proposal to the Congress at the time the DOE proposal is submitted. However, as we understand the NWPA, the Congress left it for NRC to decide which particular aspects of a DOE MRS proposal warrant NRC comment. In examining the DOE proposal, NRC decided that its most useful role would be to focus its comments on subjects falling within its later licensing responsibility.

In preparing our comments, we regarded the matter of need as primarily a business decision within the overall waste management system by which DOE intends to implement the NWPA. We did not view the MRS as needed for protection of the public health and safety.

The proposal was therefore examined from the perspective of the licensability of the facility if authorized by Congress, specifically from the standpoint of its design adequacy to protect the public health and safety. The NRC reviewed the DOE evaluation of need for the MRS but, in keeping with the focus of its comments, assumed a neutral posture.

With respect to your question on need, we believe there are attractive benefits, both operational and regulatory, to be gained by providing an MRS as part of an integrated high-level waste disposal system. These benefits are worthy of serious consideration even if an MRS is not essential for the protection of the public health and safety. Examples of operational benefits derived from an MRS integrated into the high-level waste disposal system include:

o flexibility for the DOE waste management system by decoupling the repository from the reactors and reactor sites; B705200369 870511 PDR COMMS NRCC CORRESPONDENCE PDR N

i o simplification of the surface facility operations- at j the repository;

[

o a firmer base for utilities to plan for their fuel j storage requirements; l +

t o early planning and focus for the DOE transportation j system.

j In addition to the operational benefits MRS presents certain regulatory benefits. particularly with respect to. resource

! expenditures. . Utilities are taking steps to handle and store more spent fuel at one or more of their. reactor' sites. Two

] utilities, which own multiple reactor sites, already have been

licensed to use dry storage of spent fuel. .These are in j effect small local MRS facilities. A DOE MRS .as-proposed,
would permit

1 j o fewer designs for handling and storage to be '

] reviewed, licensed and constructed; j o fewer sites and methods for spent fuel rod l consolidation and packaging; I

o

' fewer surveillance demands and more focused inspection; i

l o a greater degree of. quality assurance with'this j simplicity; .

i j The staff also examined alternatives'to the MRS considered by j DOE which seem to.have neither the operational nor regulatory i advantages of the MRS as presently contemplated. For-example,

{ the use of the MRS as a backup or near-term alternative.to a repository would accrue fewer of the benefits and most of the costs when-compared with the MRS as an integrated' step in the

! system for high-level waste disposal. Should MRS not be authorized, all packaging.and storage operations.would then he carried out at reactor sites and the repository. While it is i

technically feasible to safely store all fuel at reactor sites until a repository is ready under its current schedule, j

additional regulatory and' operational benefits identified in j the previous paragraphs would not be realized.
