PROJECT 1.0 PROJECT SCOPE This project implements certain recommended plant improvements resultant from the NRC Special Safety Team Audit Report of postulated Event V, Interfacing System LOCA (ISLOCA) events. The scope of this project includes the following:
1.1 The addition of Reactor Coolant System (RCS) pressure interlocks (P403, P404) to the Core Deluge isolation Valves (SI-MOV-871 A and SI-MOV-8718) to prevent their inadvertent opening whenever the RCS pressure is above a specified pressure of the Low Pressure Safety injection (LPSI) System and to provide annunciation if either Core Deluge isolation Valve is open and RCS pressure exceeds the specified setpoint.
1.2 The addition of the Refueling Water Storage Tank (RWST) level analog computer points to allow immediate determination of high and low tank level.

This plant design change shall be performed in accordance with 10 CFR 50.59. This modification may involve an unroviewed safety question.
The following integrated Safety Assessment Program (ISAP) Topics are associated with this change:
ISAP Topic 1.02 - High/ Low Pressure System Interface 8 Event V Analysis.
The Integrated Implementation Schedule (llS) currently shows this project to be completed in i
the Cycle 18 refueling outage (1994).
5.0 CONCEPTUAL DESIGN 5.1 Bases of Current Design 5.1 i Core Deluge Valves SI-MOV-871 A and SI-MOV-8718 The core deluge valves open to admit water from the low pressure safety injection pumps to the reactor vessel via the core deluge piping on receipt of a safety injection signal. The core deluge valves are identical 6" gate valves, each of which may be operated by an electric motor or by a manual operator.
The core deluge valves are physically located inside Containment. The motor operators for the core deluge valves are powered from MCC-5. Control power for the motor control circuits is supplied directly from the associated circuit breaker.
The core deluge valves are controlled by identical, three position gulOSE-1 AUTO-OPEN) control switches on Section C of the Main Control Board.
These control switches cause the valves to stroke open or closed on domand, and spring return to the AUTO position. (NOTE: These valves may be throttled from the MCB.)
Each contro! switch is provided with two indicating lights; red indicates the valve is open, and green indicates the valve is closed.

NUCLEAR ENGINEERING & OPERATIONS PROJECT DESCRIPTION PROJECT TITLE CONNECTICUT YANKEE EVENT V MODIFICATIONS PROJECT An additional blue indicating light is provided on Section B of the Main Control Board for each core deluge valve. If this light is out, control power is not available to the control circuit (breaker open). If the light is dim, pow 'r is available, but the associated valve is closed. If the light is brightly il.ninated, the valve is in it's open position during safety injection actuation.
The core deluge va!vas will automatically open on a safety injection signel.
The core deluge valves will fail as is on a loss of electrical power. These valves are provided with manual operators to allow manual repositioning in the event electrical power is lost. During accident conditions, however, it is probable that environmental and radiological conditions inside containment will prevent access.
The core deluge valves are normally closed with their circuit breakers shut (power available). This allows the valves to be automatically opened on receipt of a safety injection signal.
5.1.2 RWST Level Loops L-1806-A and L-1806-B instrument loop L-1806A is powered from Spec 200 cabinet NB and isolated output alarm contacts are provided for annunciation. Instrument loop L-1806B is powered from SPEC 200 cabinet NS and isolated output alarm contacts are provided for annunciation. High and low level alarm contacts are parallel f
wired within each cabinet. Annunciator C-1-1-9 is a split window type. The upper portion (C-1-1-9U) annunciates when a high and/or low level condition is sensed by RWST instrument loop L-1806A. The lower portion (C-1-1-9L) an-nunciates when a high and/or low level condition is sensed by RWST instru-ment loop L-18068.
Instrument loop L-1806A is indicated on Main Control Board indicator L1-1806-A, which displays level from 0 to 250 X 10' gallons. Instrument loop L-1806B is indicated on Main Control Board indicator LI-1806-B, which displays level from 0 to 250 X 10' gallons.
