CHANGE THE RECIPC FLOW FROM "1500 apm" TO "1822 gpm" AND CHAhlGE THE DIFFERENTIAL PRESSURE FROM "170 pe TO "195 paw ".
THESE CHANGES ARE REBUIRED TO CORRECT AN ERROR QN THE PART QF CPSL IN THE DETERMIhlATIQN OF THE MINIl'lUM FLOW AND EQUIVALENT PRESSURE USED IN THE MOST LIMITING SAFETY ANALYSIS. THE SAFETY ANALYSIS IS NOT AFFECTED NQR HAS ANY ASPECT OF ACTUAL PLANT DESIGN OR PERFORMANCE CHANGED. THIS EPROR AFFECTS ONLY THE SELECTION OF ACCEPTANCE CRITERIA FOR THIS SURVEILLANCE TEST.
THE PROPOSED FLOW IS THE MINIMUM FLOW VALUE USED IN THE CONTAINMENT HEAT REMOVAL CALCULATION WITH THE ASSUMED'EAK CONTAINMENT PRESSURE QF 42 prig.
THE DIFFERENTIAL.PRESSURE-IS THE VALUE NEEDED TQ ENSURE DELIVERY QF THE MI'NIMUN'FLOW. THIS REQUIRED PRESSUPE DOES NQT AFFECT,.:THE MINIMUM NPSH REQUIRED FOR THE SATISFACTORY PERFORMANCE QF THE PUMP-FSAR PAGEB 6 ~ 2. 1-6 AND '6. 2: 1-36 WILL 8E REVISED TQ REFLECT THE VALUE -OF1832 gpm.
THE SPRAY FLOW RATE OF 1500 gpm ON FSAR PAGE 6.5.2-5 IS CORRECT AND IS A CONSERVATIVE ABSUhlPTION FOR THE IODINE REMOVAL ANALYSIS.
CONTAINMENT SYSTEMS 3/4.6.2 DEPRESSURIZATION AND COOLING SYSTEMS CONTAINMENT SPRAY SYSTEM LIMITING CONDITION FOR OPERATION
- 3. 6. 2. 1 Two independent Containment Spray Systems shall be OPERABLE with each Spray System capable of taking suction from the RWST and transferring suction to the containment sump.

3.
Verifying that, coincident with an indication of containment spray pump running, each automatic valve from the sump and RWST actuates to its appropriate position following an RWST Lo-Lo test signal.
d.
At least once per 5 years by performing an air or smoke flow test through each spray header and verifying each spray nozzle is unobstructed.
