- saturated. Boric acid may be used, in combination with borax, for pH control.

b. START the agitator and ADD borax to the precoat tank UNTIL the solution becomes saturated.

NOTE l It will require approximately 2520 pounds of borax to obtain hot shutdown and approximately 5030 pounds of c..ax to obtain cold shutdown.

15. REPEAT Steps 4 through 14 of this section UNTIL:
s. All control rods are fully inserted, OJL
b. E&RC samples indicate boron concentration is greater than 600 ppa.

1. ESTABLISH a flow path from the SLC tank to HPCI/RCIC suction line as follows:

~~~

a. LOWER one end of a hose (stored in LEP tool box on 50 foot elevation) from the 50 foot Reactor Building elevation through the southeast pipe chase to the -17 foot elevation.

~~~

b. CONNECT one end of the hose to the HPCI And RCIC CST Suction Vent Valve, CO-V301, and the other end to the SLC tank drain line on the Reactor Building 50 foot elevation.
c. OPEN HPCI And RCIC CST Suction Vent Valve, CO-V301.
