Subject:

CESSAR Consistency Review Changes

Dear Mr. Eisenhut:

As a result of a review of the technical specifications for the first System 80" plant, several CESSAR-F chang *>s are found to be necessary.

These changes provide clarification and technical consistency of information given in CESSAR-F. A description of these changes is attached with the marked-up affected pages of the CESSAR FSAR.

Additionally, in this review, one apparent inconsistency involving cechnical information was identified in the CESSAR SER (NUREG-0852).

A suggested correction is, therefore, provided as well.

This package provides one of a series of changes identified in the technical specification review process. Other changes will be forwarded as soon as possible and will be added in a subsequent amendment to CESSAR.

If you have any questions or comments concerning these changes, please contact me or Mr. G. A. Davis of my staff at (203) 285-5207.

Very truly yours, COMBUSTION ENGINEERING, INC.

9.1.4- FUEL HANDLING SYSTEM 9.1.4.1 Desian Bases i

9.1.4.1.1 System The fuel handling system is designed for the handling and storage of fuel assemblies and control element assemblies (CEAs). Associated with the fuel handling system is the equipment used for assembly, disassembly and storage of the reactor closure head and internals. As appropriate, the fuel handling equipment included interlocks, travel limiting features, and other protective devices to minimize the possibility of mishandling or equipment malfunction that could result in inadvertent damage to a fuel assembly and potential fission product release.

The refueling water provides the coolant medium during spent fuel transfer.

The spent fuel pool is provided with a pool coo. ling and purifications system.

~

( All spent fuel transfer and storage operations are designed to be conducted underwater to insure adequate shielding during refueling and to permit visual control of the operation at all times. The arrangement of the "uel handling system is shown in Figure 9.1-1.

l. The principle design criteria for the fuel and CEA handling equipment i'

(refueling machine, fuel transfer equipment, spent fuel handling machine, l CEA change platform and new fuel and CEA elevators) are as follows:

a. For non-seismic operating conditions, the bridges, trolleys, hoist units, hoisting cable, grapples and hooks conform to the requirements i
