LIMITING CONDITION FOR OPERATION SURVEILLANCE REQUIREMENT 3.8 5.
Accumulator System 4.8 5
Accumulator System (Table 4.8-4)
A.
The four accumulator systems shall satisfy the following conditions A.
Surveillance and testing of the whenever the reactor coolant system accumulator system shall be pressure exceeds 1000 psig except performed as follows:
as specified in 3.8.5.A.5.
1.
Each accumulator shall be 1.
The pressure and level of the pressurized to at least 600 accumulator tanks shall be psig and ghall contain minimum checked once a shift. At each of 819 ft3 and a maximum of 5% increase in level, the 868 ft3 of water.
boron concentration will be checked.
2.
Each accumulator shall contain 2.
The accumulator boron concen-water borated to at least tration shall be checked 2000 ppm.
monthly.
3.
Each accumulator's isolation 3
The accumulator check valve valve shall be open.
operability (SI-8948A, B, C, and D and SI-8956A, B, C,and D) will be verified at each refueling outage by opening the accumulator outlet isola-tion valve (MOV-SI8808A, B, C, and D) and verifying a de-crease in accumulator level and by a leakage test to de-termine that no gross valve leakage is experienced.
