Dear Mr. Denton:

Enclosed herewith are 60 copies of additional information regarding SER Open Item No. 25, RCIC Temperature Sensors, which was previously identified as requiring clarifying infor mation to complete NRC review.

-If you require additional information or clarification, please do not hestitate to contact this office.

Very truly yours, ..; ,

i 46 1 Open Item No. 25 NRC Request:

1

a. Provide an illustration to show where the temperature sensor elements are located.

~~-

b. Describe why a failure (steam line break) will not isolate both systems (HPCI and RCIC).

Response

+

a. See the attached table for the location of the temperature sensor elements .

b. To the maximum extent possible, the temperature sensor elements are placed to minimize the possibDity of interference between sensors and isolation of both the RCIC and HPCI systems. In order to be more conservative, for the condition of a break in the RCIC steam i supply line it is assumed that HPCI also becomes unavailable.and vice versa. This is d,iscussed in detail in FSAR sections 3C.4.3.9 and 3C.4.4.9. As discussed therein, the plant can nevertheless be safely shut down. Note that each pipe break analysis considers, in addition to consequential effects, the worst single active failure associated with each pipe break.
