REACTIVITY CONTROL SYSTEMS 3/4.1.2 BORATION SYSTEMS FLOW PATHS - SHUTDOWN LIMITING CONDITION FOR OPERATION 3.1.2.1 As a minimum, one of the following boron injection flow paths shall be OpERABLE and capable of being powered from an OPERABLE emergency power source.

a . A flow path from the'oric acid makeup tank via either a boric acid pump or a gravity feed connection and any charging pump to the Reactor Coolant System if only the boric acid makeup tank in Specification 3.1.2.7a is OPERABLE, or

b. The flow path from the refueling water tank via either a charging pump or a high pressure safety injection pump*

to the Reactor Coolant System if only the refueling water tank in Specification 3.1.2.7b is OPERABLE.

APPLICABILITY: MODES 5 and 6.

ACTION:

With none of the above flow paths OPERABLE, suspend all operations involving CORE ALTERATIONS or positive reactivity changes until at least one injection path is restored to OPERABLE status.

SURVEILLANCE RE UIREMENTS 4.1.2.1 At least one of the above required flow paths shall be demonstrated OPERABLE:

a ~ At least once per 31 days by ver ifying that each valve (manual, power operated or automatic) in the flow path that is not-.

locked, sealed, or otherwise secured in position, is in its

~

correct position.

<<The flow path from the RWT to the RCS via a single HPSI pump shall only be established if: (a) the RCS pressure boundar does not exist, or (b) no char in um s are o erable. h~g-pumps bl A-th 14 e era&~PS+-header-she+}-be-veH+md-cased-and-have-t4 'w~moved.

REACTIVITY CONTROL SYSTEMS CHARGING PUMPS - SHUTOOWN LIMITING CONOITION FOR OPERATION 3.1.2.3 At least one charging pump or high pressure safety injection pump* in the boron injection flow path required OPERABLE pursuant to Specification 3.1.2el shall be OPERABLE and capable of being powered from an OPERABLE emergency bus.

APPLICABILITY: MODES 5 and 6.

ACTION:

With no charging pump or high pressure safety injection pump* OPERABLE, suspend all operations involving CORE ALTERATIONS or positive reactivity changes until at least one of the required pumps is restored to OPERABLE status.

SURVEILLANCE RE UIREMENTS 4.1.2.3 At least one of the above required pumps shall be demonstrated OPERABLE by verifying the charging pump develops a flow rate of greater than or equal to 40 gpm or the high pressure safety injection pump develops a total head of greater than or equal to 2571 ft. when tested pursuant to Specification 4.0.5.

• The flow path from the RWT to the RCS via a single HPSI pump shall be established only if: (a) the RCS ressure boundary does not exist, or (b) no char in um s are o erable. arg+ng-pum e n eatup-and-coo%down-vates-shal-1 be-l-iaN+d-i~ccor4anc~h Rg. 8".Hb Af-PCS-h 0 -
