3/4.6.3 CONTAINMENT ISOLATION VALVES (Continued) i I

Section C of Table 3.6-1 contains a listing of manual valves that are normally l

closed and assumed to be closed under design basis accident conditions, but

+

which may be opened intermittently for service, maintenance or test during l

1 normal operation provided adequate administrative controls are implemented to j

i ensure operator action is taken to close such valves in the event of an i

accident, t

All valves in Section A, B or C are considered OPERABLE for containment isola-i i

i l

tion purpose if tney are indeed locked, sealed or otherwise secured in the i

closed position and leakage through the affected flow path is shown to be within limits when tested pursuant to 10 CFR 50 Appendix J.

(

4 Section D of Table 3.6-1 contains a listing of valves which operate automati-i cally on an ESFAS signal to prevent or mitigate the consequences of the design j

basis accident. Surveillance requirement 4.6.1.1.a is not applicable to such i

valves. The OPERABILITY of such valves is determined by ESFAS response time testing of Specification 3/4.3.2.

Valves in Section D that are locked, sealed j

or otherwise secured in their ESFAS actuated position will permit performance of their safety function and are, therefore, considered OPERABLE pursuant to 3

j this specification.

i j

3/4.6.4 COMBUSTIBLE GAS CONTROL i

The OPERABILITY of the equipment and systems required for the detection 1

I and control of hydrogen gas ensures that this equipment will be available to q

maintain the hydrogen concentration within containment below its flammable l

i limit during post-LOCA conditions.

Either recombiner unit is capable of j

controlling the expected hydrogen generation associated with 1) zirconium-1 water reactions, 2) radiolytic decomposition of water and 3) corrosion of l

metals within containment. These hydrogen control systems are consistent with j

the recommendations of Regulatory Guide 1.7, " Control of Combustible Gas Concentrations in Containment Following a LOCA", March 1971.

The containment dome air circulators are provided to ensure adequate 3

mixica of the containment atmosphere following a LOCA. The mixing,ag_ tion of tMr containment dome air circulators combined with the containment spray system and the containment emergency fan coolers will prevent localized accumulations of hydrogen from exceeding the flammable limit.

CONTAINMENT SYSTEMS BASES 3/4.6.3 CONTAINMENT ISOLATION VALVES (Continued)

Section C of Table 3.6-1 contains a listing of manual valves that are nornally closed and assumed to be closed under design basis accident conditions, but which may be opened intermittently for service, maintenance or test during normal operation provided adequate administrative controls are implemented to ensure operator action is taken to close such valves in the event of an accident.

All valves in Section A, B, w C,,'or.E are considered OPERABLE for containment l

isolation purpose if they are indeed locked, sealed or otherwise secured in the closed position and leakage through the affected flow path is shown to be within limits when tested pursuant to 10 CFR 50 Appendix J.

Sections D1 and D2 of Table 3.6-1 each contains a listing of valves which operate automaticalli toiopen on an ESFAS signal to prevent or mitigate the consequences of the design bas ~is" accident. Surveillance requirement 4.6.1.1.a is not applicable to such valves. The OPERABILITY of such valves is determined by ESFAS response time testing of Specification 3/4.3.2. Vahc in Section D that are locked, scaled cr otherwise secured in their ESFf,5 actuated pccition.ill permit performance of their safety function and are, therefore, considered OPERf3LE pursuant to thi Specification.

Section E'of: Table-3.6-11contains':allisting of Valves?whichioperate automatically to close on1an ESFASisignal, : valves with dual! ESFAS functionst(0 pen /Close),' and check valves.. ; Surveillance. Requirement 14.6.1.1:.aiis notfapplicable to'such valves. The 0PERABILITY of!such valves is determined by:ESFAS;responset. time testingiof: Specification"3/4.3.2L The appropriate Action statement (s) of those Limiting Conditions: for Operati' n pertaining to:the; valve (s)for:: system in which o

it.is installed :'shall be applicable.

3/4.6.4 COMBUSTIBLE GAS CONTROL The OPERABILITY of the equipment and systems required for the detection and control of hydrogen gas ensures that this equipment will be available to maintain the hydrogen concentration within containment below its flammable limit during post-LOCA conditions.

Either recombiner unit is capable of controlling the expected hydrogen generation associated with 1) zirconium-water reactions, 2) radiolytic decomposition of water and 3) corrosion of metals within containment.

i These hydrogen control systems are consistent with the recommendations of Regulatory Guide 1.7, " Control of Combustible Gas Concentrations in Containment Following a LOCA", March 1971.

The containment dome air circulators are provided to ensure adequate mixing of the containment atmosphere following a LOCA. The mixing action of the containment dome air circulators combined with the containment spray system and the containment emergency fan coolers will prevent localized accumulations of hydrogen from exceeding the flammable limit.

BASES 3/4.6.3 CONTAINMENT ISOLATION VALVES (Continued) l All valves in Section A, B;

C,LorlE are considered OPERABLE for containment isolation purpose if they are indeed~ locked, sealed or otherwise secured in the closed position and leakage through the affected flow path is shown to be within limits when tested pursuant te 10 CFR 50 Appendix J.

l Sections D1 and-D2 of Table 3.6-1 each contains a listing of valves which operate l

automatically to open on an ESFAS signal to prevent or mitigate the consequences of I

the design basis ~ accident. Surveillance requirement 4.6.1.1.a is not applicable to i

such valves. The OPERABILITY of such valves is determined by ESFAS response time testing of Specification 3/4.3.2.

"alve; in Sectier D that are locked, scaled or otherwi;c secured in their ESFf.S actuated positica..ill permit performance of their safety function and are, therefore, censidered OPERf2LE purcuant to this specificaticn.

Section.E;of Table 3.6-1*contains allisting offvalves whi~ch operate automatically'to close. on an ESFAS signal, valves with dual ESFAS functionsL(Open/Close), and check valves.. Surveillance Requirement.4.6.1.1.a is-n'ottapplicable to such valves. The i

OPERABILITY-of such valves is determined by: ESFAS1 response-time. testing of Specification 3/4.3.2. The appropriate: Action'. statement (s):lof:those Limiting Conditions for Operation pertaining to theivalve(s): or. system in which it is-installed shall -be applic'able.

i 3/4.6.4 COMBUSTIBLE GAS CONTROL j

The OPERABILITY of the equipment and systems required for the detection and control of hydrogen gas ensures that this equipment will be available to maintain the l

hydrogen concentration within containment below its flammable limit during post-LOCA conditions.

Either recombiner unit is capable of controlling the expected hydrogen generation associated with 1) zirconium-water reactions, 2) radiolytic decomposition of water and 3) corrosion of metals within containment. These hydrogen control systems are consistent with the recommendations of Regulatory Guide 1.7, " Control of Combustible Gas Concentrations in Containment Following a LOCA", March 1971.

The containment dome air circulators are provided to ensure adequate mixing of the containment atmosphere following a LOCA. The mixing action of the containment dome air circulators combined with the containment spray system and the containment emergency fan coolers will prevent localized accumulations of hydrogen from exceeding the flammable limit.
