During normal operation, this exclusion would apply to the High Head Safety Injection subsystem. During shutdown cooling operation, the exclusion would apply to the single required centrifugal charging pump and operating RH pump, in addition to the ECCS piping in connunication with the operating pumps.
Because the centrifugal charging pumps are not equipped with pump casing vent valves, and the pump design and system piping configuration allow the pumps to be maintained pumps under positive pressure when in standby, manual venting of these is not required.
The surveillance requirement to ultrasonically examine selected portions of piping involves the idle CV pump discharge pi valve on the pump discharge and miniflow lines,and pingthe upstagnant to the first checkof the portion piping upstream of the ISIB801A/B adjacent to the vent valve ISIO45. This will provide added assurance that the piping is water solid.

- i INSERT A For Unit 2, Surveillance Requirement 4.5.2.b.1 requires that the RH and Si pump casings and discharge piping high point vent valves be vented on a 31 day frequency. This venting surveillance does not apply to subsystems in communication with operating systems because the flows in these systems are sufficient to provide confidence that water hammer which could occur from voiding would not result in unacceptable dynamic loads. During shutdown cooling l operation, the exclusion would apply to the operating RH pump, in addition to the ECCS piping in communication with the operating pump.
The TS 4.5.2.b.3 surveillance requirement to ultrasonically examine selected portions of piping involves the idle CV pump discharge piping up to the first check valve on the pump discharge and miniflow lines, the stagnant portion of the piping upstream of the 2Sl8801A/B adjacent to the vent valve 2S1045, and the piping at the 2CV206 valve if the 2B CV pump is idle.

BRAIDWOOD - UNITS 1 & 2 B 3/4 5-2 a AMENDMENT NO. 83
INSERT A For Unit 2, F,urveillance Requirement 4.5.2.b.1 requires that the RH and $1 pump casings and discharge piping high point vent valves be vented on a 31 day frequency. This venting surveillance does not apply to subsystems in communication with operating systems because
, the flows in these systems are sufficient to provide confidence that water hammer which could
, occur from voiding would not result in unacceptable dynamic loads. During shutdown cooling i
operation, the exclusion would apply to the operating RH pump, in addition to the ECCS piping i in communication with the operating pump.
)
! The TS 4.5.2.b.3 surveillance requirement to ultrasonically examine selected portions of piping
! involves the idle CV pump discharge piping up to the first check valve on the pump discharge and miniflow lines, the stagnant portion of the piping upstream of the 2S18801 A/B adjacent to 4
the vent valve 2S1045, and the piping at the 2CV206 valve if the 28 CV pump is idle. This examination will provide added assurance that the piping is water solid.
