SUBJECT:

MEETING WITH BALTIMORE GAS AND ELECTRIC COMPANY (BG&E) -

ANE CUTECH, INC. ,

DATE/TIHE: November 4, 19683 9:00 a.m.

LOCATION: Room 6-B-ll, One White Flint North Building, Rockville, MD i ATTENDEES: Fqe enclosure 1.

i

. PURPOSE: Discussion of a license application under 10 CFR Part 72 i I BG&E for dry spent fuel storage at the 1,ita of its calvert Cliffs nuclear power plant. -

DISCUSSION:

After introduction of attendees, BG&E spoke. BG&E generally followed its j~

agenda and presentation (see enclosure 2). However, for purposes of familiarizing many of those present with the NUTECH NUHOMS-24P design (which  ;

, BG&E proposes to reference for use in its application) for a concrete module and stainless steel canister dry storage system, NUTECH made a presentation l on the system (see enclosure 3). f 1 ,

i BG&E seeks to avoid loss of full-core reserve for the two Calvert Cliffs units q in 1992. Consequently, BG8E )lans to file its ap ,

i enclostre 2 final page for sc1edule requirements) .

plicationlicense Assuming in May 1989 (see approval.

BG&E would construct an initial set of 24 modules. A total of 120 modules to

., give capacity through year 2016 is planned. BG&E spent fuel is Combustion

! Engineering (CE) 14 x 14 pressurized water reactor fuel. Proposed limits of 4.3 to 4.5 weight percent initial enrichment and 47,000 MWD /MTU were mentioned. l Use of CE fuel would in general lead the applicant to downsizing the NUHOMS-24P,  !

i as presently designed (reference: Project No. M-49), although the stainless i steel dry shielded canister (DSC) diameter is not expected to change.  !

, i Leland C. Rouse 2 N O V 0 s 1989 Some arr.endmer.ts to Calvert Cliff operating licenses associated with dry storage are expected. These would include areas, such as security and provision for a single-failure proof crane to accomodate a transfer cask encompassing a DSC for fuel leading in the reactor pool. Under BG&E's proposal, a loaded DSC after sealing would be moved in the transfer cask designed to hold it from the reactor to the module site for offloading into a module (see enclosure 2, Figure 2.1) on a flood-free site.

During the meeting, NUTECH mentioned that there was potential for designing a transfer cask to also meet the requirements of 10 CFR Part 71 for direct offsite shipment of loaded DSC's at the end of licensed storage. At the end of the meeting, BG&E explained that an incentive of $15,000 per DSC was included in BG&E's contract with NUTECH to encourage such direct offsite shipment of DSC's to foster compatibility by direct offsite disposition of spent fuel to the Department of Energy at the termination of storage.
