3.3 EMERGENCY CORE COOLING SYSTEM (Continued)

If Specification a. and b. cannot be met, an orderly shutdown shall c.

te initiated and the reactor shall be in hot shutdown condition within 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />, and cold shutdown within the next 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />.

BJULi.A The normal procedure for starting the reactor is, first, to heat the primary coolant to nesr operating temperature by running the primary coolant pumps. The reactor is then made critical rods and diluting boron in the primary coolant.'g withdrawing control With this mode of start up, the energy stored in the primary coolant during the approach to criticality is substantially equal to that during power operation and, therefore, all engineered safety features and auxiliary cooling systems are required to be fully operable. During low temperature physics tests, there is a negligible amount of stored energy in the primary coolant; therefore, an accident comparable in severity to the design basis accident is not possible and the engineered safeguards' systems are not required.

The SIRW tank contains a minimum of 250,000 gallons of water containing 1720 ppm boron.

This is sufficient boron concentration to provide a 5%

shutdown margin with all control rods withdrawn and a new core at a temperature of 60'F.

Heating steam is provided to maintain the tank above 40*F to prevent freezing. The 1% boron (1720 ppm) solution will not precipitate out above 3PF.

The source of steam durin steam line in the turbine cycle. g normal plant opec' ion is extraction The limits for the safety injection tank pressure and volume assure the required amount of water injection during an accident and are based on values used for the accident analyges.

The minimum 174 inch level corresponds to-a volume of 1040 ft and the maximum 200-inch level 3

corresponds to a volume of 1176 ft.

Prior to the time the reactor is brought critical, the valving of the safety injection system must be checked for correct alignment and appropriate valves locked. Since the system is used for shutdown cooling.

the valving.ill be changed and must be properly t.ligned prior to start-up of the reactor.

The operable status of the various.systcms and components is to be demonstrated by periodic tests. A large fraction of these tests will be pr* formed while the reactor is operating in the power range.

If a moonent is found to be inoperable, it will.be possible in most cases to

- d ect repairs and restore the system to full operability within a relatively short time.

For a single component to be 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 3-31 Change No. 1 Amendment No JJ7,136 i

I

3.3 EMERGENCY CORE COOLING SYSTEM hili (continued) demonstrate that the maximum fuel clad tismperatures that could occur over the break size spectrum are well below the melting temperature of zirconiur (3300'F).

Malfunction of the Low Pr6ssure Safety injection Flow control valve could defeat the Low Pressure Injection feature of the ECCS; therefore, it is disabled in the 'open' mode (by 19 t.ing the air supply) during plant operation. This action assures that it will not block flow during Safety Injection.

The inadvertent closing of any one of the Safety injection bottle isolation valves in conjunction with a LOCA has not been analyzed.

To provide assurance that this will not occur, these valves are electrically locked open by a key switch in the >.ontrol room.

In addition, prior to

}

critical the valves are checked open, and then the 480 volt breakers are 5

opened. Thus, a failure of a breaker and a switch are required for any of the valves to close, insuring both HPSI pumps are inoperable when the PCS temperature is

<260'F or the shutdown cooling isolation valves are open eliminates PCS mass additions due to inadvertent HPSI pump starts.

Both HPSI pumps starting in conjunction with a charging / letdown imb lance may cause 4

10CFR50 Appendix G limits to be exceeded when the PCS temperature is

<260'F.

When the PCS temperature is 2 430'F, the-pressurizer safety

-valves ensure that the PCS pressure will not exceed 10CFR50 Appendix G.

The requiopert to have both HPSI trains operable above 325'F provides added assurat.ce that the effects of a LOCA occuring under LTOP conditions would be mitigated.

If a LOCA occurs when the primary system temperature is less than or equal to 325'F, the pressure would drop to the level where low pressure safety injection can prevent core damage.

Therefore, when the PCS temperature is 2260'F and $325'F operation of the HPSI system would not cause the 10CFR50 Appendix G limits to be exceeded nor is HPSI system operation necessary for core cooling.

HPSI pump testing with the HPSI pump manual discharge valve closed is permitted since the closed valve eliminates the possibility of-pump testing being the cause of a mass addition to the PCS.

3.17 LNSTRUMENIATION AND CONTROL SY&TiMS (Cont'd) if the bypass is not effected, the out of service channel (Power Removed) assumes a tripped condition (except high rate of change power, variable high power and high pressurizer pressure), W which results in a one out-of three channel logic, if, in the 2 of 4 logic system of either the reactor protective system or the engineered safeguards system, one channel is bypassed and a second channel manually placed in a tripped condition, the resul%g l gic is 1 of 2.

At rated power, the minimum operable variable high power level channels is 3 in order to provide adequate flux tilt detection.

If only 2 channels are operable, the reactor power level is reduced to-70% rated power which protects the reactor from possibly exceeding design peaking factors due to undetected flux tilts.

The engineered safeguards system provides a 2 out of 4 logic on the signal used to actuate the equipment connected to each of the 2 emergency diesel generator units.

Two source-range channels are available any time reactivity changes l

are deliberately being introduced into the reactor and the neutron power is.not visible on the wide range nuclear instrumentation or above 10"% of rated power.

This ensures that redundant source range instrumentation is available to operators to monitor effects of reactivity changes when neutron power levels are only visiole on the source-range channels.

In the event only one source-range channel is l available and the neutron power level is sufficiently high that it is being monitored by both channels of wide-range instrumentation, a j

startup can be performed in accordance with footnote (d) of Table 3.17.4.

The Recirculation Actuation System (RAS) initiates on a 1 out of 2 taken twice logic scheme.

Any one channel declared inoperable shall be placed in a bypass condition to ensure protection from an inadvertent RAS Actuation.

Since the bypassing of a channel introduces the possibility for a failure to receive an automatic RAS actuation signal, the time period in the bypassed condition is limited.

The Zero Power Mode Bypass can be used to,) bypass the low flow, steam generator low pressure, and TM/LP trips (

for all four Reactor Protective system channels to perform control rod testina or to perform low power physics testing below normal operating temperatures. The requirement to maintain cold shutdown boron concentration when in the bypass condition provides additional assurance that an accidental criticality will not occur.

To allow low power physics testing at_ reduced temperature and pressure, the requirement for cold shutdown boron concentration is not required and the allowed power is increased to 10"%.
