Technical Specification 3.5.1.1 requires that each cold leg injection accumulator shall be operable with the isolation valve open, contain a volume of borated water between 7857 and 8071 gallons with a boron concentration between 1900 and 2100 ppm, and a nitrogen cover pressure of between 385 and 447 psig. With one cold leg injection accumulator inoperable, except as a result of a closed isolation valve, the inoperable accumulator must be restored to operable status within one hour or the reactor must be placed in at least Hot Standby within the next six hours and Hot Shutdown within the following six hour Contrary to the above, on August 9 and 10,1985, the Unit 2 number 3 loop cold leg injection accumulator was technically inoperable in that it did not contain a volume of borated water between 7857 and 8071 gallons or a concentration of boron between 1900 and 2100 ppm for a period of seven hours and forty minutes.
