1. Difference Description The Containment Air Recirculation and cooling System Fans utilize Ventilation Chilled Water as their cooling medium I i while the generic reference plant uses CCW. I 2. Justification This system is not required to operate following a DBA so the post accident CCW cooling is not required. It is required for loss of offsite power so it is sequenced on as well as the Ventilation Chilled Water System, i ~ 3.

O 1. Difference Description CPSES design does not incorporate a Motor Driven Feedvater Pump 2. Justification CPSES utilizes two 50% capacity feedvater pump. The dual admission feedvater pump turbine drivers operate with steam from two sources. One pump is required up to 50% power and from 50% to full power both are required. The Condensate Pumps can be used to pump water at lover pressures. 3.

4 1 l. Difference Description Due to the preheater arrangement in CPSES SGs the feedvater isolation signal closes more valves than the same signal of the generic plant reference. i r i 2. Justification A feedvater isolation signal closes the F.W. Preheater Valves and F.W. Splitflow Bypass Valve in addition to the normal valves. This ensures feedvater isolation to the SGs. These additional valves are i checked in the steps for feedvater isolation of the emergency procedures. 3.

O 1. Difference Description The generic plant reference refers to the Motor Driven AFW pumps being lined up to 2 SGs. CPSES's Motor Driven AFW pumps are normally lined up to 2 SGs but have the capability to be lined up to h SGs. 2. Justification A norr. ally closed interconnection between the motor driven pump discharge lines permits either pump to feed all four SGs. This provides a method for maintaining SG vater level on a long-term basis, but will not normally be used. This difference is an improvement over-the generic. 3.

I O 1. Difference Description The Reactor Vessel Level Indication System at CPSES will not be operational until the first refueling outage f I 4 2. Justification The steps that dealt with RVLIS in the emergency procedure were revised as specified in the background documentation of the ERG's .i to meet plant design at this time.

O 1. Difference Description Containment Spray pumps get a start signal on j a SI as well as Phase "B" and Manual signals i 2. Justification The CSS discharge valves open on a "P" signal which comes from a Phase "B" or Manual actuations. Having the pump start en an SI anticipates the need of the pump if conditions become more severe. This difference is an improvement over the reference plant. ~ b d DATE '/-0-8 3.

O 1. Difference Description The generic reference plant uses a two Contain-ment Spray Pump arrangement, while CPSES has four contaiment spray numus. 2. Justification The redundancy requirements of the CSS are satisfied by dumplicating 2-100% capacity trains, with each train having 2-50% capacity pumps. This difference does not allow one pump failure to remove the capacity of one train completely. 3.

O 1. Difference Description CPSES's design includes an auto switchover of the RWST to the containment sump as RHR pump suction. 2. Justification On an RWST low-lov level signal, coincident with an "S" signal, the containment sump valves to RHR pump will open. This arrangement is also set up with reset switches.(independent of SI reset), that can reset this function after SI is reset. This difference is an. improvement over the reference plant. 3.

O 1. Difference Description The Pressurizer PORV's at CPSES utilizes Nitrogen gas as their pneumatic driver. 2. Justification The PRZR PORV's are pneumatic actuated vavles which respond to a signal from a pressure sensing system or to manual control as per the M-drawing, CPSES uses nitrogen as the pneumatic driver for the PORVs. This is considered a minor difference which does not affect the plant.. bh 54 DATE 7-d-8 3.

i-1. Difference Description The CPSES plant specific procedure foldout O page items was revised to incorporate the criteria for determinine whether Adverse Containment Parameters should be used. The FRC red path summary was removed in order to accomodate the above mentinned i change. 2. Justification The generic procedures as written. never mention when Adverse Containment parameters should be used. By placing them on the i foldout page, the operator will have a quick reference to be able to make that determination. The red path summary was removed since the ooerator as well as the STA vill continually be monitorine the critical safety function status trees on the computer or manually if not available. 3.

Justification This system is not required to operate following a DBA so the post accident CCW cooling is not required. It is required for loss of offsite power so it is sequenced on as well as the Ventilation Chilled Water System, 3.

-~ I 1. Difference Description CPSES design does not incorporate a Motor a i i Driven Feedwater Pump i i i !i i 2. Justification CPSES utilizes two 50% capacity feedwater pump. The dual admission feedvater pump turbine drivers operate with steam from 4 two sources. One pump is required up to 50% power and from 50% to full power both are required. The Condensate Pumps can be used to pump water at lower pressures. Ib b DATE '/-6-F(f 3.

1. Difference Description Due to the preheater arrangement in CPSES SGs the feedvater isolation signal closes more valves than the sene signal of the generic plant reference. 2. Justification A feedvater isolation signal closes the F.W. Preheater Valves and F.W. Splitflow Bypass Valve in addition to the normal valves. This ensures feedvater isolation to the SGs. These additional valves are checked in the steps for feedvater isolation of the emergency procedures. 3.

1. Difference Description The generic plant reference refers to the Motor Driven AFW pumps being lined up to 2 SGs. CPSES's Motor Driven AFW pumps are normally lined up to 2 SGs but have the capability to be lined up to h SGs. 2. Justification A normally closed interconnection between the motor driven pump discharge lines permits either pump to feed all four SGs. This provides a method for maintaining SG water level on a long-term basis, but will not normally be used. This difference is an improvement over the generic. k //~IwN DATE 7-lo -O 3.

1. Difference Description Containment Spray pumps cet a start sienal on a SI as well as Phase "B" and Manual signals 2. Justification The CSS discharge valves open on a "P" signal which comes from a Phace "B" or Manual actuations. Having the pump start on an SI anticipates the need of the pump if conditions become more severe. This difference is an improvement over the reference plant. 3.

r 1. Difference Description CPSES's design includes an auto switchover of the RWST to the containment sump as RHR pump suction. 2. Justification On an RWST low-lov level signal, coincident with an "S" signal, the containment sump valves to RHR pump will open. This arrangement is also set up with reset switches (independent of SI reset), that can reset this function after SI is recet. This difference is an improvement over the reference plant. 3.
