Whenever the water level in the refueling pool is less than elevation 40 feet 3 inches [see (7) below for reference elevation),-the-following specifications shall apply:
- a. Two of the following methods of decay heat removal shall be-operable, and at least one shall be in operation circulating reactor coolant:
(1) Residual heat removal (RHR) pump 6-14A with one RHR..train.
- (2) Residual heat removal (RHR) pump G-14B with a second RHR train.
One refueling water pump taking suction from the refueling pool through the recirculation heat exchanger (with supporting heat removal systems operating), and discharging via the safety injection system piping to one reactor coolant loop cold leg.
- b. With less than the required methods of decay heat removal operable, immediately initiate corrective action to return the required methods of decay_
heat removal to operable status as soon as possible or-to establish water-level in the refueling pool of at least 40 feet 3 inches :[see.
(7) below for reference elevation).
- c.
With none of the required methods of decay heat removal in operation, suspend all operations involving a reduction in boron concentration of the reactor coolant system. Imnediately -inItiate corrective action to return the required decay heat removal method to operation. In addition, within four hours, close all containment penetrations that provide direct access from the containment atmosphere to the outside atmosphere.
- 5.
With the reactor vessel head closure bolts less than fully tensioned or with the head removed, the more restrictive of the following reactivity conditions shall be met.
- a. A shutdown margin greater than 5% ak/k.
- b. A boron concentration greater than or equal to 2,000 ppm.
- 6. The reactor shall be subcritical for at least 148 hours0.00171 days <br />0.0411 hours <br />2.44709e-4 weeks <br />5.6314e-5 months <br /> prior to movement of irradiated fuel in the reactor pressure vessel.
