Minimum volumes (including a 10% snfsty fcctor) as specified by Figure 3.2.1 for the boric acid addition tank or 27,633 gal' ons of 2270 ppm boron as boric acid solution in the borated water storage tank (3) will each satisfy this
-requirement.
The specification assures that adequate supplies are available whenever the reactor is.hcated above 200 F so that a singic failure will not prevent boration to a cold condition.
tion given include the boron necessary to accountThe minimum volumes of boric acid solu-for xenon decay.
The principal method of adding boron to the primar* system is to pump the con-centrated boric acid solution (8700 ppm boron, minicam) into the makeup tank using the 25 gpm boric acid pumps.
Using only one of the two boric acid pumps, the required volume of boric acid can be injected in less than three hours. The alternate method of addition is t: inject boric acid from the boro-ated water storage tank using the makeup pumps; the required volume of boric acid can be injected in less than two hours using only one of the makeup pumps.
Concentration of boron in the boric acid addition tank may be higher than the concentration which would crystallize at ambient conditions. For this reason and to assure a flow of boric acid is available when needed this tank and its associated piping will be kept 10 F above the crystallization temperature for 0
the concentration present. Once in the makeup system, the concentrate is suffi-ciently well mixed and diluted so that normal system temperatures assure boric acid solubility.
