ENCLOSURE 1 BEAVER VALLEY-2 OPERATING LICENSE REQUEST FOR ADDITIONAL INFORMATION 440.21 In its' August 10, 1984, response to SER Open Item $161, regarding

~' '

the reliability of a residual heat removal system that meets GDC-34, the Duquesne Light Company stated:

"In the event the system is unavailable, the safety grade

~

systems discussed in FSAR Section 5.4.7.4.6 are qualified to .

perform the function of removing residual heat from the reactor core for normal, abnormal, and design base accident conditions."

However, there is no Section 5.4.7.4.6 in the FSAR. '

This response also states:

" Class IE safety-related equipment associated with the ECCS, AFWS, and S/G PORV's are identified in Table 3.11-1."

However, Table 3.11-1 has been removed from the FSAR (Amendment 8). Thus this response is not acceptable.

To be acceptable, clear descriptions of the shutdown and long term coolihg methods that conform to GDC-34 are needed in the FSAR and also confirmation that all of the components used in these methods are environmentally qualified.
