Letter from E. E.

APS, to G.
W. Knighton, NRC, dated November 5, 1984,
Subject:
Dear Mr. Knighton:
The reference letter provided revised PVNGS FSAR pages reflecting changes due to field testing results and in support of the PVNGS Technical Specifica-tions.
In discussions with members of your staff it was determined that the 59 second closure time changes to FSAR table 6.2.4-2 of the reference letter are not appropriate at this time.
Attached is a revised FSAR table 6.2.4-2 indicating appropriate closure times.
This table supercedes the table provided in the reference letter.
Also, attached are some minor editorial additions for FSAR pages 5.1-36, 6.2.1-38, 6.2.1-39, table 6.2.1-28, 6.2.4-22, table 10.1-1, 10.4-47.
Very truly yours, ggU~~k E. E.

PVNGS FSAR CONTAINMENT SYSTEMS The power access purge used during operation at power has 8-inch containment penetrations sized in accordance with the guidelines of Branch Technical Position CSB 6-4.
The 8-inch diameter valves (CPA-UV 04A, 4B, CPB-UV005A, 5B) are designed to close in less tha S seconds after receipt of I
a CIAS or a CPIAS.
This minimizes the amount of containment atmosphere mass released to the environment in the unlikely event that a
LOCA should.occur with the power access purge valves open.

Refueling purge valves (42 in.) are ANSI rated 75 lbs.
Power access valve bodies are hydrotested at 225 psi.
Refueling purge valves are hydrotested at 112 psi.

PVNGS FSAR steam isolation v OTHER FEATURES OF STEAM AND POWER CONVERSION SYSTEM ives.
The turbine controls and associated valves are powered from the dc bus.
10.4.9.2.2 Component Description Principal components are listed in table l0.4-6.
10.4.9-2.3 System Operation For emergency operation, normal flow is from the condensate tank to either the Seismic Category I motor-driven AFS pump or to the steam turbine-driven Seismic Category I AFS pump which are located in the main steam support structure.
An alternate supply of water is provided by cross connections to the reactor makeup tank.
A minimum flow recirculation system is provided on each pump discharge with recirculation to the condensate tank.
Each pump can supply either steam generator with feedwater.
