('u. T ,'.*; q (I) The engineered sefety features valves associated with each of the above systems shall be operable or locked in the ES position.

3.3.2 In addition to 3.3.1 above, the following dCCS equipment shall be operable when the reactor coolant system is above 350F and irradi-ated fuel is in the core:

(A) Two out of three high pressure injection (makeup) pumps shall be maintained operabic, powered from independent essential busses, to provide redundant and independent flow paths.

(B) Engineered safety features valves associated with 3.3.2.a above shall be operable or locked in the ES position.

i 3.3.3 In addition to 3.3.1 and 3.3.2 above, the following ECCS equipment shall be operable when the recctor coolant system is above 800 psig:

(A) The tye core flooding tanks shall ea- Ontain an indicated minimum of 13 + 0.4 feet (1040 + 30 ft S) of borated water at 600 f; 25 psig.

(B) Core flooding tank boron concentration shall not be less than 2270 ppm boron. 1 (C) The electrically operated discharge valves from the core flood tanks shall be open and breakers locked open and tagged.

(D) One of the two pressure instrument channels and one of the two level instrument channels per core flood tank shall be vperable.

3.3.4 The reactor shall not be made critical unless the following equipment in addition to 3.3.1, 3.3.2, and 3.3.3 above is operable.

(A) Two reactor building spray pumps and their associated spray nozzle headers and four reactor building emergency cooling ,i fans and associated cooling units. ,

1 l

(B) The sodium hydroxide tank shall contain an irdicated 34 _h*,l ft. of 18 +2:6wt.%solutionsodiumhydroxide (19,500 lb. j; 2500 lb.) .

(C) All manual valves in the main discharge lines of the sodica thiosulfate and sodium hydroxide tanks shall be locked open.

(D) Engineered safety feature valves and interlocks associated with 3.3.1, 3.3.2, and 3.3.3 shall be operable or locked in the ES position.

3.3.5 Maintenance shall be allowed during power operation on any component (s) in the high pressure injection, low pressure injection, service water,

. reactor building spray and reactor building cooling 37 8004220p}g

3.3 EMERGENCY CORE COOLING, REACTOR BUILDI."G COOLING AND REACTOR BUILDING SPRAY SYSTEMS Applicability Applies to the emergency core cooling, reactor building cooling and reactor building spray systems.

Objectivity To define the conditions necessary to assure immediate availability of the emergency core cooling, reactor building cooling ar.d reactor building spray systems.

Specification 3.3.1 The following equipment shall be operable whenever containment integrity is established as required by Specification 3.6.1:

(A) One reactor building spray pump and its associated spray nos:le header.

(B) One reactor building cooling fan and its associated cooling unit.

(C) Two out of three service water pumps shall be operable, powered from independent essential buses, to provide re- .

dundant and independent flow paths.

(D) Two engineered safety feature actuated low pressure injection pumps shall be operable. ;

(E) Both low press 5 :e injection coolers and their cooling water supplies shall be operable.

(F) Two BNST level instrument channels shall be operable.

(G) The corated water storage tank shall contain a level of 37.5,+{*{ft. (362,000 + 13,000 gallons) of water having a concentration of 2470+ 200 ppm boron at a temperature not less than 40F. The manual-' valve on the discharge line from the borated water storage tank shall be locked open.

(H) The four reactor building emergency sump isolation valves to the LPI system shall be either manually or remote-manually operable.
