- a. During each refueling interval and following =aintenance or

- b. After a satisfactory test of the emergency loading sequence !
(h.5.1), the M. U. Pu=p and its required supporting auxiliaries vill be started =anually by the operater and a test signal vill be applied to the high pressure injection valves MU-V16A, B, C, D to de=cnstrate actuation of the high pressure injection 61A system for emergency core cooling operatien. . The test vill be considered satisfactory if the valves have l cc=pleted their travel and the M. U. pu=ps are running as evidenced by the control board component operating lights. Mini =un acceptable flev must be greater than or equal to 200 g;n per injection leg and greater than or equal to 500 g;= per HPI pu=p. 61A
- c. The correct limit switch setting of MU-716A, B, C, D will be verified within four hours of any =aintenance en the valve or operator that affects the limit switch setting, when the High Pressure Injection System is required to be operable.
- d. Testing which requires HPI flev thru MJ-V16A/3/C/D shall be cen-ducted only under either of the following conditions:
- 1) T avg. shall be greater than 3200F.
- 2) Head of the Reactor Vessel shall be removed.

- a. During each refueling period and folleving maintenance or mcdification that affects system flev characteristics, syst a pumps and high point vents shall be vented, and a systen test shall be conducted to de=onstrate that the system is operable.
The auxiliaries required for low pressure injection are all included in the emergency loading sequence specified in h.5.1.
- b. The test vill be considered satisfactory if the decay heat pu=ps listed in h.15.lb have been cuece:sfully started and the decay heat injection valves and the decay heat supply valves
.have ec=pleted their travel as evidenced by the centrol beard ec=ponent 0;cratinc lichts. "i-" acceptable flev must be , L. '
