L 4.5.4- _ ACCIDENT RECIRCULATION SYSTEMS LEAKAGE Anolicability

- Applies to those portions of the Decay Heat, Building Spray, and Make-Up Systems, which are required to contain post accident sump recirculation fluid.

i Obiective -

[ To maintain a low leakage rate from the accident recirculation systems to prevent significant off-site l exposures.

i l Soecification _,

L 4.5.4.1 The total maximum allowable leakage from the applicable portions of the Decay L . Heat, Building Spray and Make-Up System components as measured during l - refueling tests m Specification 4.5.4.2 shall not exceed 15.0 gallons per hour.*

4.5.4.2 During each refueling interval the following tests of the applicable portions of the Decay Heat Removal, Building Spray and Make-Up Systems shall be conducted to determine leakage:

a. The applicable portion of the Decay Heat Removal System that is outside i

containment shall be leak tested with the Decay Heat pump operating or by hydrostatic testing at no less than 350 psig, except as specified m "b" b.- Piping from the Reactor Building Sump to the Building Spray pump and Decay Heat Removal System pump suction isolation valves shall be pressurc l tested at no less than 55 psig.

l l c. The applicable portion of the Building Spray system that is outside

- containment shall be leak tested with the Buildmg Spray pumps operating and BS-V-1 A/B closed or by hydrostatic testing at no less than 350 psig, except as i specified in "b".

L d. The applicable portion of the Make-Up system on the suction side of the l Make-Up pumps shall be leak tested with a Decay Heat pump operating and DH-V-7A/B open or hydrostatic testing at no less than 200 psig.

e. The applicable portion of the Make-Up system from the Make-Up pumps to

! the containment boundary shall be leak tested with a Make-Up pump )

operating or by hydrostatic test at no less than 3050 psig. j

f. Visual inspection shall be made for leakage from components of these systems. leakage shall be measured by collection and weighing or by another equivalent method

- NOTE: This leal. rate limit is only applicable for the Cycle 13 operating cycle.

l i

Bases Ihe leakage rate limit of 15 gph (measured in standard cold gallons) for the accident recirculation

- portions of the Decay Heat Removal, Building Spray, and Make-Up Systems is based on ensuring that potential leakage after a loss-of-coolant accident will not result in off-site dose consequences in excess of those calculated to co aply with the 10 CFR 100 limits (Reference I and 2).
