TABLE 6.2-17 (Cont'd)

(Page 19 of 19)

(12) only non-essential systems require diverse signals for automatic isolation.

Therefore, this column is not applicable, (NA), for essential systems, sea d l

(13)

These valv== are normally# closed and will only l

l be opened l

(14)

Diverse isqlation signals are not sensed as discussed in Section/6.2.4.3.1.

i (15)

These val es are normally closed, will be open only during re etor shutdown, are interlocked to open only on low r actor pressure, and connect to a closed system outside ontainment.

Therefore, closure times less than 6 seconds are not required.
