SURVEILLANCEREQUIREMENTS (Continued) b.
At least once per 31 days by; 1.
Verifying the continuity of the explosive charge.
2.
Determining that the available weight of sodium pentaborate is greater than or equal to 5500 Ibs and the concentration of boron in solution is within the limits of Figure 3.1.5-2 by chemical analysis."
3.
Verifying that each valve, manual, power operated or automatic, in the flow
'ath that is not locked, sealed, or otherwise secured in position, is in its correct position.
c.
Demonstrating that, when tested pursuant to Specification 4.0.5, the minimum flow requirement of 41.2 gpm at a pressure of greater than or equal to 1224 psig is met.
d.
At least once per 18 months during shutdown by; 1.
Initiating one of the standby liquid control system loops, including an explosive valve, and verifying that a flow path from the pumps to the reactor pressure vessel is available by pumping demineralized water into the reactor vessel
~ The replacement charge for the explosive valve shall be from the -same manufactured batch as the one fired or from another batch which has been certified by having one of that batch successfully fired.
Both injection loops shall be tested in 36 months.
2.
""Demonstrating that all heat traced piping is unblocked by pumping from the storage tank to the test tank and then draining and flushing the discharge piping and test tank with demineralized water.
This test shall also be performed anytime water or boron is added to the solution or when the solution temperature drops below the limitof Figure 3.1.5-1.
This test shall also be performed whenever both heat tracing circuits have been found to be inoperable and may be performed by any series of sequential, overlapping or total flow steps such that the entire flow path is included.
