Attachment No. 1 Haddam Neck Plant Proposed Changes to Technical Specifications Definitions--Containment Integrity r
November 1990 go12Or.oa.13 901127 f4 DOCK O'300 l{13 FDR
4 DEFINITIONS CONTAINMENT INTEGRITY 1.6 CONTAINMENT INTEGRITY shall exist when:
a.
All penetrations required to be closed during accident conditions are either:
1)
Capable of being closed by an OPERABLE containment automatic isolation valve system, or 2)
Closed by manual valves, blind flanges, or deactivated automatic valves secured in their closed positions, except as noted below:
Note 1)
Normally-closed isolation valves SS-S0V-150A, SS-S0V-1508, SS-S0V-1500, SS-S0V-1500, SS-S0V 151A,
[.
SS-S0V-151B, SS-SOV-151C, and SS-S0V-1510 which fail closed on loss of power and are capable of being closed within 60 seconds of a containment isolation actuation signal (CIAS) by an operator utilizing normal control switches and normal position indication within the main control room may be opened for periodic testing.
Note 2)
Normally-closed manual isolation valves SI-V-863A, B, C, and D, SA-V-413, NG-V-473, and SS-V-999A may be opened for periodic surveillance and containment boundary (vent and drain) manual valves may be opened for diagnostic checks to ensure Technical Specification lindts or to ensure system operability are man.+ained. While these valves are open, a locally statioud ogerator will be in direct communication with t..e main control room.
This ensures the valves are capable of being closed
=
within 60 seconds of a CIAS.
b.
The equipment hatch is closed and sealed, c.
The air lock is in compliance with the requirements of Specification 3.6.1.3, d.
- The containment leakage rates are within the limits of Specification 3.6.1.2, and
- e..
The sealing mechanism associated with each penetration (e.g.,
welds, bellows, or 0-rings) is OPERABLE.
CONTROLLED LEAKAGE 1.7 CONTROLLED LEAKAGE shall be that seal water flow returned from the reactor coolant pump number 2 seals.
