3.

The Standby Liquid Control System conditions must satisfy the following equation:

\\I f

E

\\>1 C

Q 13% wt 86 gpm 19.8% atom j

where, C = Sodium Pentaborate Solution Concentration (% weight)

Q = Pump Flow Rate (gpm) 3.

Pump Flow Rate: At least against a system head of once per month each pump 1225 psig.

loop shall be functionally tested by pumping boron solution to the test tank.

At least once per quarter check and record pump flow rate against a system head of 1225 psig.

E = Boron-10 Enrichment (% atom 4.

Enrichment:

Following each Boron-10) addition of boron to the solution tank, calculate enrichment within 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br />.

Verify results by analysis within 30 days.
