3-25 Amendment No. 4, 78, 98, 119, 124, 162. 190
l Bases A reactor shutdown following power operation requires removal of core decay heat.
Normal decay heat removal is by the steam generators with the steam dump to the condenser when RCS temperature is above 250*F and by the decay heat removal system below 250'F.
Core decay heat can be continuously dissipated'up to 15 percent of full power via the steam bypass to the condenser as feedwater in the steam generator is converted to steam by heat absorption.
Normally, the capability to return feedwater flow to the steam generators is provided by the main feedwater system.
The main steam safety valves will be able to relieve to atmosphere the total steam flow if necessary.
Below 5% power, only a minimum number of Main Steam Safety Valves need to be operable as stated in Technical Specification 3.4.1.2.1 and 3.4.1.2.2.
This is to provide Steam Generator overpressure protection during hot functional testing and low power physics testing. Additionally, when the Reactor is between hot shutdown and 5% full power operation, the over power trip setpoint in the RPS nhall be set to less than 5% as is specified in Technical Specification 3.4.1.E.2.
The minimum number of valves required to be operable allows margin for testing without jeopardizing plant safety.
Plant specific analysis shows that one Main Steam Safety Valve is sufficient to relieve reactor coolant pump heat and stored energy when the reactor is subcritical by 1%
delta K/K for at least one hour. Other plant analyses show that two (2) Main Steam Safety Valves on either OTSG are more than sufficient to relieve reactor coolant pump heat and stored energy when the reactor is below 5% full power operation but had been subcritical by 1% delta K/K for at least one hour since power operation above 5% full power.
According to Technical Specification 3.1.1.2a, both steam gener.ators shall be operable whenever the reactor coolant average temperature is above 250'F. This assures that all four (4) Main Steam Safety Valves are available for redundancy. During power operations at 5% full power or above, if Main Steam Safety Valves are inoperable, the power level must be reduced, as stated in Technical Specification 3.4.1.2.3 such that the remaining safety valves can prevent overpressure on a turbine trip.
In the unlikely event of complete loss of off-site electrical power to the station, decay heat removal is by either the steam-driven emergency feedwater pump, or two half-sized motor-driven pumps.
Steam discharge is to the atmosphere via the Main Steam Safety Valves and controlled atmospheric relief valves, and in the case of the turbine driven pump, from the turbine exhaust.
t Both motor-driven pumps, or the steam-driven EFW pump are required initially to remove decay heat with one EFW pump eventually sufficing.
If emergency feedwater is required during surveillance testing, acceptably minor operator action may be required to ensure both motor-driven pumps are available.
The minimum amount of water in the condensatt storage tanks, contained in Technical Specification 3.4.1.1., will allow cooldown to 250*F with steam being discharged to the atmosphere.
After cooling to 250*F, the decay heat removal system is used to achieve further cooling.

3.6 REACTOR BUILDING Applicability Applies to the containment integrity of the reactor building as specified below.
Objective To assure containment integrity.
Specification 3.6.1 Containment integrity as defined in Section 1.7, shall be maintained whenever all three of the following conditions exist:
a.
Reactor coolant pressure is 300 psig or greater, b.
Reactor coolant temperature is 200*F or greater.
c.
Nuclear fuel is in the core.
3.6.2 Containment integrity shall be maintained when both the reactor coolant system is open to the containment atmosphere and a shutdown margin exists that is less than that for a refueling shutdown.
3.6.3 Positive reactivity insertions which wculd result in a reduction in shutdown margin to less than 1% A k/k shall not be made by control rod motion or boron dilution unless containment integrity is being maintained.
3.6.4 The reactor shall not be critical when the reactor building internal pressure exceeds 2.0 psig or 1.0 psi vacuum.
3.6.5 Prior to criticality following refueling shutdown, a check shall be made to confirm that all manual containment isolation valves which should be closed are closed and are conspicuously marked.
3.6.6 While the reactor is critical, if a reactor building isolation valve (other than a purge valve) is determined to be inoperable in a position other than the required position, the other reactor building isolation valve in the line shall be verified to be OPERABLE.
If the inoperable valve is not restored within 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br />, the OPERABLE valve will be closed or the reactor shall be brought to HOT SHUTDOWN within the next 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> and to the COLD SHUTDOWN condition within an additional 30 hours3.472222e-4 days <br />0.00833 hours <br />4.960317e-5 weeks <br />1.1415e-5 months <br />.
3.6.7 The hydrogen recombiner shall be operable during REACTOR CRITICAL, HOT STANDBY and POWER OPERATION. With the hydrogen recombiner inoperable, 1
restore the recombiner to operable status or bring the reactor to H0T SHUTDOWN within seven (7) days.
3.6.8 While containment integrity is required (see T.S. 3.6.1), if a 48" reactor building purge valve is found to be inoperable perform either 3.6.8.1 or 3.6.8.2 below.
