Dear Mr. Knighton:
Letter from E. E.

APS, to G.
W. Knighton, NRC, dated December 10, 1984 (ANPP-31414);
Subject:
PVNGS FSAR Update Radwaste Systems and Effluent Streams.
Letter from E. E.
Van Brunt, Jr.,
APS, to G.
W. Knighton, NRC, dated December 10, 1984 (ANPP-31397);
Subject:
PVNGS FSAR Update Radiation Protection Design Features.
As a result of discussions with your staff on December 18,
- 1984, APS is providing additional information to clarify the referenced letters.
Reference (1) indicates that the backflushable purification filter and crud subsystem has been changed to a disposable cartridge filter in order to meet 10 CFR 61 criteria.
The new purification cartridge filter will be handled in the same manner as the existing purification cartridge filter (the old design has one backflushable and one cartridge purification filter).
The cartridges will be handled remotely as described in FSAR Sections 12.1.2.3.2.I and 12.3.1.1.
1.1 by the use of shielded handling system.
ALARA is maintained as the operator is never exposed to unattenuated radiation from the cartridge.
Reference (2) indicates that a single set of graphite based packing is used in place of double packing on larger valves.
The graphite packs are considered superior to conventional packings in the respect that the use of graphite yarn provides a continuous run around the valve that avoids the split encountered with other packings.
Also, grafoil packings conform to the opening better, thereby reducing the potential for leakage.
Accordingly, leakage remains minimal with the change to graphite based packings.
If you have any further questions, please contact Mr. William Quinn of my staff.
Very trul u
