Mr. H. R. Denton November 16, 1981 In response to this request, Licensee.has proposed the attached Technical Specification changes. Specific changes on each of the attached pages have been indicated by margin bars. A discussion of these changes follow. >

1. Specification 15.3.1.A.1.b has been changed by substituting the terminology " rated power" for-

" thermal power". Thetspecification, currently written as "l% of thermal'p'ower", does not define a specific core thermal output.

2. A new Specification 15.3.1.A.2 has been provided, modeled after the standardized technical speci-fications, to require redundant operable decay heat removal methods when reactor coolant tempera-tures are between 350 F and 140*F. A section has also been included to clarify the decay heat removal requirements when the reactor coolant temperature is less than 140 F and to specify a permissible operating condition to permit periodic maintenance of the residual heat removal system.

3. The Basis for Specification 15.3.1.A has been modified to include a discussion of, and basis for, the new Specification 15.3.1.A.2.

4. Specification 15.3.3.A.2 has been reworded. As presently written, this Specification requires the reactor to be placed in a cold shut-down condition if a residual heat removal pump is out of service for greater than 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br />. This action results in putting tfe reactor coolant system in a condition without redundant decay heat removal capa-bility. Therefore, the Specification has been rewritten to permit keeping the reactor in a hot standby condition with reactor coolant temperatures between 500*F and 350'F so that the steam generators may be used for redundant decay heat removal while the residual heat removal syrtem is repaired.

I 5. Specification 15.3.8.A.4 has been changed so that it is consistent with new Specification 15.3.1.A.2.

Reference is made to the entire residual heat removal loop rather than simply the pump. This specific change was suggested by the NRC_ Staff. A sentence has also been added to permit securing the operating residual heat removal loop for up to one hour in an eight hour period when flow would interfere with refueling operations.
