SUBJECT:
Post-LOCA Containment Sump PURPOSE:
Appeal NRC interpretation of SRP 6.5.2 0.
KEY DECISIONS Item Decision 1.A NRC agreed to accept C-E s generic design of the Iodine Removal System (IRS) as long as that design retains the capability for refill of the Spray Chemical Storage Tank over the course of the postulated accident.
1.
'DISCUSSION A.
C-E directed NRC s attention to how the current IRS design meets the specific and implied requirements and guidance of SRP 6.5.2.
The hydrazine (N H4) system has a long-term partition coefficient of greater than 5,000.
That partition coefficient is independent of pH and is sufficient to guarantee an offsite dose, which meets 10CFR100.
NRC accepted this argument and agreed to'close the item in the CESSAR docket.

(2)
