INSTRUMENTATION AND CONTROL SYSTEMS BRANCH SITE VISIT AGENDA FOR WNP-2 1.

Prel iminar Discussi ons a.

Discussion of plant layout (from drawings) and general plant tour.

b.

Brief identification of outstanding issues.

c.

Brief overview of the station distribution system from one line diagrams (4160, 480, 5 120 Vac, and 125 Vdc).

1 d.

Discussion of physical separation requirements applicable to WNP-2.

2.

Control Room a.

Review general layout of the control room..

b.

Review annunciation provided when the ECCS low pressure permissive (high pressure/low pressure interlock) is satisfied.

c.

Review the layout of the RPS and ESF instrument cabinet internals (identification of safety and associated circui ts, separation between redundant circuits, and isolation provided for interdivisional wiring).

d.

Review the'nternal wiring of the main control boards (physical separation between redundant safety circuits and between protection systems and control and annunciation circuitry).

e.

Review annunciation provided upon transfer to the remote shutdown panel.

f.

Review the safety relief valve (SRV) position indication resulting from TMI Action Plan Item II.D.3.

g.

h

~

Review the control rod position indication.

Review the recirculation flow instrumentation shared by the redundant RBM channels (specifically, the armored/shielded cable which penetrates the fire barrier between RBM channels).

k.

Review RBN data bus runs.

Review the RBM bypass switch (separation between channels).

Review -the containment pressure, water level, and hydrogen concentration instrumentation; TMI Action Plan Item II.F.l (4), (5),

and (6).

Review annunciation for scram discharge volume (SDV) high level trip bypass and the method used to effect this bypass (keylock j

switches).

m.

Review Standby Liquid Control System initiation and associated alarms (high and low solution temperature and tank level).

n.

Review all ranges of reactor vessel water level instrumentation provided (indicators and recorders).

o.

Review the bypassed and inoperable status indication provided for the

RPS, fSF systems, and other systems required for safety.

3.

Shutdown from Outside the Control Room a.

Review how reactor trip may be accomplished from outside the control room.

b.

c ~

Review location of transfer switches.

l<alk through the expected remote shutdown scenario (from control room to the remote shutdown panel) and observe the instrumentation and controls used to effect shutdown of the reactor.

d.

Review remote shutdown panel internals.

e.

Review the remote shutdown panel location, accessibility, and habit-ability. (ventilation provided).

f.

Review location(s ) from which shutdown is effected gi ven a loss of division I power at the remote shutdown panel.

~

V r

4.

Reactor Buildin, Auxiliar Buildin, and Tur bine Buildin a.

Review the safety relief valve (HARV) accoustic monitoring instrumentation installed as a result of TNI Action Plan Item II.D.3.

b.

Review the RPS M-G Sets and their associated electrical protection assemblies (EPAs).

c.

Review the scram discharge instrument volume and associated instrumentation.

d.

Review 120 Vac and 125 Vdc emergency buses (chargers, batteries, inverters, etc.)

e.

Review ESF pump rooms (HPCS,

RCIC, RHR, LPCS) and 'local start capability.

f.

Review the following pla+ equipment:

ADS valves and solenoids HSIVs.

Diesel generators (including storage tanks, transfer

pumps, and local control).

SLCS pumps, explosive squib valves, and boric acid tank.

Shutdown Service Water pumps and instrumentation.

5.

Circuit Traces a.

Trace redundant channels of protection system circuitry used to trip the reactor on turbine stop or governor valve position (from the limit switches or pressure switches to the RPS cabinets).

b.

Trace the instrument piping and associated circuits used for the high pressure/low pressure interlock function for redundant low pressure ECCS systems.

This should include interlocks for both the suction valves from the wecirculation lines and the injection valves.

~ c.

Trace the circuitry (from sensors to protection system cabinets) used to transfer HPCS and RCIC pump suction to the suppression pool on CST low level.

6.

Local Instrument Racks/Pi in a.

Review separation between redundant reactor vessel level instrumentation (from vessel taps, to transmitters).

b.

Review turbine first stage pressure instrument taps and transmitters.

7.

Ca abilit for Testin a.

Walk through the planned testing procedures (channel functional

tests, logic tests, etc.) for RPS and or ESF system instrument and logic channels.
