EXHIBIT B

REACTIVITY CONTROL SYSTEMS SURVEILLANCE REQUIREMENTS (Continued)

b. At least once per 31 days by:

1. Verifying the continuity of the explosive charge.

2. Determining that the available net weight of sodium pentaborate is greater than or equal to 1171 lbs 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 path that is not locked, sealed, or otherwise secured in position, is in its correct position.

4. Starting both pumps and recirculating demineralized water to the test tank.

c. Demonstrating that, when tested pursuant to Specification 4.0.5, the i

minimum flow requirement of-41.2 gpm at a pressure of greater than or equal to 1220 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. No replacement squib valve shall be used that will exceed its shelf life or useful life, as applicable during its inservice period.

2. Verifying that the relief valve does not actuate during recirculation to the test tank.

3. Demonstrating that all heat traced piping is unblocked by pumping from the storage tank to the test tank and then draining and flushing the piping with demineralized water.**

4. Demonstrating that the storage tank heaters are OPERABLE by verifying the expected temperature rise of the sodium pentaborate solution in the storage tank after the heaters are energized.

e. At each refueling outage by:

1. verifying that a minimum Boron-10 enrichment of 85 atom percent exists by analyzing a sample taken from the tank.

• This test shall also be performed anytime water or boron is added to the solution or when the solution temperature drops below the limit of 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, over-1apping or total flow path steps such that the entire flow path is included.
