Dear ifr. Crouse:

H0rnstein StmJECT: DECAY llEAT DEMOVAL CAPABILITY REDUNDANCY On June 11, 1980, the f!PC requested that you amend the /,pendix A Technical Specifications for your facility with respect to provisions for decay heat renoval capability to provide for redundancy in all operational nodes. He enclosed, for your cuidance, nodel Technical Specifications which would provide

1. ~

an acceptable resolution of this issue.

Toledo Edison Company subnitted an application, Iten 3, Toledo Edison Company letter dated December 26,1980 (flo. 669), to anend the Davis-Besse Facility Operatino License in response to our request. 11e have reviewed the application and find that your proposed changes to the Technical Specifications follow our model Technical Specifications closely for all nodes of operation except for node 3.

Your proposed Specification 3.4.1.2, applicable in nodes 3, 4, and 5, would provide for decay heat renoval redundancy by requiring at least two of the following loops to be operable:

1.

Reactor Coolant loop 1 and associated stean generator l

2.

Reactor Coolant Loop 2 and associated steam generator l

3.

Decay Heat Renoval Loop 1 4

Decay Heat Renoval loop 2 It is further specified that at least one of the above loops nust be in operation.

As presently proposed, Specification 3.4.1.2 would pernit operation in node 3 with one reactor coolant loop and associated stean generator in operation and the renaininq reactor coolant loop inoperable provided at least one decay heat renoval loop is operable.

In node 3, RCS pressure and temperature can far exceed the design conditions of the Decay Heat Renoval Systen, therefore, Specification 3.4.1.2 does not appear to provide for the required redundancy for the reactor coolant loop operation when the unit is in node 3.

Please submit a nodification to your proposed anendnent to assure the required redundancy, or axplain how redundancy, when in node 3, is assured by your current proposal.
