- 1. Difference Description- CPSES does not utilize a bynass line T hot and T cold measurements for the nurnose of RCS average temneratures.
- 2. Justification The bypass manifold arrangement has been replaced with a N-16 monitor and an in-line T cold measurement. The N-16 power monitor measures N-16 present in RCS due to r.eutron activation of oxygen con-tained in water. This is used with T cold to determine T avg .

.'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.
- 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 ij4 checked in the steps for feedvater isolation of the emergency procedures.

- ~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 1
provides a method for maintaining SG water level on a long-term basis, but vill not normally be used. -This difference is an improvement over the generic.

- 1. ' Difference Description Containment Spray pumps get a start signal on a SI as well as Phase "B" and Manual signals

that can reset this function after SI is reset. This difference is an
