BaalE I

The Chemical and Volume Control System provides control of the Reactor i

Coolant System boron inventory. This is normally accomplished by using boric l

[

- acid transfer pumps which discharge to the suction of each unit's charging i

pumps. The Chemical and Volume Control System contains four boric acid transfer pumps. Two of these pumps are normally assigned to each unit but, 4

a valving and piping arrangements allow pumps to be shared such that three out

]

of four pumps can service either unit. An attemate (not normally used) method I

- of boration is to use the charging pumps taking suction directly from the.

}

refueling water storage tank. There are two sources of borated water available l

- to the suction of the charging pumps through two different paths; one from the refueling water storage tank and one from the discharge of the boric acid i

transfer pumps.

l A.

The boric acid transfer pumps can deliver the boric acid tank contents l

(7.0% solution of boric acid) to the charging pumps.

i B.

The charging pumps can take suction from the volume control tank, the j

boric acid transfer. pumps and the refueling water storage tank.

i Reference is made to Technical Specification 3.3.

I l

The quantity of boric acid in storage from either the boric acid tanks or the l

refueling water storage tank is sufficient to borate the reactor coolant in order to l

reach COLD SHUTDOWN at any time during core life.

i j

Approximately 6000 gallons of the 7.0% solution of boric acid are required to

[

meet COLD SHUTDOWN conditions. Thus, a minimum of 6000 gallons in the l

boric acid tank is specified. An upper concentration limit of 8.5% boric acid in the tank is specified to maintain solution solubility at the specified low temperature limit of 112 degrees F.

l The Boric Acid Tank (s) are supplied with level alarms which would annunciate if j

a leak in the system occurred.

Amendment Nos. 199 and 199 O

l TS 3.2-5 For one-unit operation, it is required to maintain available one charging pump l

with a source of borated water on the opposite unit, the associated piping and valving, and the associated instrumentation and controls in order to maintain the capability to cross-connect the two unit's charging pump discharge headers.

In the event the operating unit's charging pumps become inoperable, this permits the opposite unit's charging pump to be used to bring the disabled unit to COLD SHUTDOWN conditions. ' Initially, the need for the charging pump l cross-connect was identified during fire protection reviews.

The requirement that certain valves remain closed during REFUELING I

SHUTDOWN and COLD SHUTDOWN conditions, except for planned boron dilution or makeup activities, provides assurance that an inadvertent boron dilution will not occur. This specification is not applicable at INTERMEDIATE i

SHUTDOWN, HOT SHUTDOWN, REACTOR CRITICAL, or POWER l

Basia The normal procedure for starting the reactor is, first, to heat the reactor coolant l

to near operating temperature by running the reactor coolant pumps. The reactor is then made critical by withdrawing control rods and/or diluting boron in the coolant. With this mode of startup the Safety injection System is required to l

be OPERABLE as specified. During LOW POWER PHYSICS TESTS there is a l

negligible amount of energy stored in the system. Therefore, an accident l

comparable in severity to the Design Basis Accident ic not possible, and the full l

capacity of the Safety injection System would not be necessary.

The OPERABLE status of the subsystems is to be demonstrated by periodic l tests, detailed in TS Section 4.11. A large fraction of these tests are performed while the reactor is operating in the power range. If a subsystem is found to be I inoperable, it will be possible in most cases to effect repairs and restore the subsystem to full operability within a relatively short time. A subsystem being l inoperable does not negate the ability of the system to perform its function, but it reduces the redundancy provided in the reactor design and thereby limits the ability to tolerate additional subsystem failures. In some cases, additional (

components (i.e., charging pumps) are installed to allow a component to be inoperable without affecting system redundancy.

Amendment Nos.199 and 199

TS 3.3-4 If the inoperable subsystem is not repaired within the specified allowable time period, the reactor will initially be placed in HOT SHUTDOWN to provide for reduction of the decay heat from the fuel, and consequent reduction of cooling requirements after a postulated loss-of-coolant accident. If the malfunction (s) is not corrected the reactor will be placed in COLD SHUTDOWN following normal shutdown and cooldown proced es.

Assuming the reactor has been operating at full RATED POWER for at least 100 days, the magnitude of the decay heat production decreases as follows after a unit trip from full RATED POWER.

Time After Shutdown Decav Heat. (% of RATED POWER) 1 min.

Placing and maintaining the reactor in HOT l

SHUTDOWN significantly reduces the potential consequences of a loss-of-l coolant accident, allows access to some of the Safety injection System components in order to effect repairs, and minimizes the plant's exposure to thermal cycling.

unforeseen problems (i.e., possibly the need of major maintenance). In such a i

case, the reactor is placed in COLD SHUTDOWN.

l The accumulators are able to accept leakage from the Reactor Coolant System without any effect on their operability. Allowable inleakage is based on the volume of water that can be added to the initial amount without exceeding the volume given in Specification 3.3.A.2.

TS 3.3-5 The accumulators'(one for each loop) discharge into the cold leg of the reactor coolant piping when Reactor Coolant.

1 However, to assure that the accumulator valves satisfy the single failure criteria, l

they will be locked, sealed or otherwise secured open by de-energizing the valve motor operators when the reactor coolant pressure exceeds 1000 psig.

I The operating pressure of the Reactor Coolant System is 2235* psig and accumulator injection is initiated when this pressure drops to 600 psia. De-l energizing the motor operator when the pressure exceeds 1000 psig allows sufficient time during normal startup operation to perform the actions required to de-energize the valve. This procedure will assure that there is an OPERABLE flow path from each accumulator to the Reactor Coolant System during POWER OPERATION and that safety injection can be accomplished.

The removal of power from the valves listed above will assure that the systems of which they are a part satisfy the single failure criterion.

i For Unit 2 Cycle 12, Reactor Coolant System nominal operating pressure may be reduced to 2135 psig.

TS 3.4-4 l

In addition to supplying water to the Containment Spray System, the refueling water storage tank is also a source of water for safety injection following an accident. This water is borated to a concentration which assures reactor shutdown by approximately 5 percent Ak/k when all control rods assemblies are inserted and when the reactor is cooled down for refueling.

The Component Cooling System is an intermediate cooling system which serves both reactor units. It transfers heat from heat exchangers containing lI reactor coolant, other radioa::tive liquids, and other fluids to the Service Water l

System. The Component Cooling System is designed to (1) provide cooling i

water for the removal of residual and sensible heat from the Reactor Coolant f

System during shutdown, cooldown, and startup, (2) cool the containment l

recirculation air coolers and the reactor coolant pump motor coolers, (3) cool the letdown flow in the Chemical and Volume Control System during POWER OPERATION, and during residual heat removal for continued purification, (4) l cool the reactor coolant pump seal water return flow, (5) provide cooling water l

for the neutron shleid tank and (6) provide cooling to dissipate heat from other j

reactor unit components.

j i

i l

The Component Cooling Water Subsystem has four component cooling water l-pumps and four component cooling water heat exchangers. Each of the l

component cooling water heat exchangers is designed to remove during

)

i l

normal operation the entire heat load from one unit plus one half of the heat load common to both units. Thus, one component cooling water pump and one l

component cooling water heat exchanger are required for each unit which is at POWER OPERATION. Two pumps and two heat exchangers are normally l

operated during the removal of residual and sensible heat from one unit during I

[

cooldown. Failure of a single component may extend the time required for cooldown but does not affect the safe operation of the station.

A test signal is applied to initiate automatic operation action and verification is made that the components receive the safety injection signal in the proper sequence. The test may be performed with the pumps blocked from starting. The test demonstrates the operation of the valves, pump circuit breakers, and automatic circuitry.

During reactor operation, the instrumentation which is depended on to initiate safety injection is checked periodically, and the initiatinrj circuits are tested in accordance with Specification 4.1. In addition, the active components (pumps and valves) are to be periodically tested to check the operation of the starting circuits and to verify that the pumps are in satisfactory running order.
