.2 REACTOR COOLANT SYSTEM COLD SHUT 00WN LIMITING CONDITION FOR OPERATION 3.4.1.4 Two# residual heat removal loops shall be OPERABLE
- and at least one RHR loop shall be in operation.**
APP LICABILITY: M0 E 5.##
ACTION:
a.
With less than the above required loops operable, immediately initiate corrective action to return the required loops to OPERABLE status as soon as possible.
b.
With no RHR loop in operation, suspend all operations involving a reduction in boron concentration of the Reactor Coolant System and imediately initiate corrective action to return the required RHR loop to operation.
SURVEILLANCE REQUIREMENTS 4.4.1.4 At least one residual heat removal loop thall be verified to be
.in operation and circulating reactor coolant at least once per 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />.
One RHR loop may be inoperable for up to two hours for surveillance testing, provided the other RHR loop is OPERABLE and in oper > tion.
Additionally, four filled reactor coolant loops, with at least two steam generators with their secnndary side water levels greater than or equal to 5% (narrow range), may be substituted for one residual heat. removal inop.
- A r.eactor coolant pump shall not be started with one or more of the RCS cold leg temperatures less than or equal to' 312*F unless 1) the pressurizer water volume is less than 1650 cubic feet (equivalent to approximately 92% of level), or 2) the secondary water temperature of each steam generator is less than 50*F above each of the RCS cold leg temperatures.
I Systems supporting RHR loop operability may be excepted as follows:
1.
The normal or emergency power source may he inoperable.
b.
One service water header may be out of service provided the equipment listed in Table 3.4-3 is OPERABLE.
The residual ' heat removal pumps may be de-energized for up to 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> provided 1) no operations are permitted that would cause dilution of the reactor coolant system boron concentration, and 2) core outlet temperature is maintained at least 10'F below saturation temperature.
