Licensee _ Action on preyi_o_usly__ Identified items,

a.

Unresolved _ _ Item

I

(Closed) 456/88003-01:

Inadequate nrveillance test shift brief.

^

The licensee's resporise to this item was to issue a special

4

J

oaerating order entitled "Surveillance Briefing Responsibilities."

T1e order rectrphasizes the respcnsibility of the control room

supervisor to review upcoming surveillances regardless of frequency

and to conduct or direct others to conduct appropriate briefings

coninensurate with the complexity of the evolution and the expected

.

L

results.

The inspector has rnonitored general surveillance briefings

subsequent to the eighteen-month Bus 142 undervoltage test, during

which the inspector raised the concern of inadequate shift briefs.

The results of the reviews show that the shift briefs appear to be

adequate, with all participating persons being knowledgeable of

expected surveillance test activities and their impact on plant

operations. This item is considered closed,

b.

V,iolation

(Closed) 456/87042-01: Manipulation of reactor controls by an

unauthorized individual on September 20, 1987. The inspector has

monitored the implerrentation of the licensee's corrective actions

for this event. On October 1,1987, the Nuclear Operations Division

issued a letter which defines the personnel allowed to maritpulate

reactor controls.

This letter was reviewed with licensed shif t

personnel.

In addition, the Station Training Department issued a

letter on October 18, 1987 (periodically updated), specifying by

name the individuals in license training who currently qualify for

the exerption described in 10 CFR 55. A copy of this letter is

available in the control room.

The inspectors' periodic monitoring of the above corrective action

has identified no further violations in this area.

This item is

considered closed.

No violations or deviations were identified.

(Closed) 456/87048-L2:

Loss of Offsite Power Due to Inadvertent Deluge

.

System Actuation Resulting from a Mispositioned Yalve.

During the

performance of a deluge system surveillance, a loss of offsite power

occu rred. The root cause of this event was a mispositioned auxiliary

drcin valve.

The licensee has concluded that the mispositioning occurred

as early as August 20, 1987, during performance of a surveillance between

August 20, 1987 and September 11, 1987.

Corrective actions taken included

revising two fire protection procedures to verify valve positions prior

to starting surveillances and to verify deluge system valve positions

monthly. Also, corrective actions included a requirerc.ent for personnel

to obtain shift engineer or station control room engineer permission

i

prior to entry into the deluge system area. The inspector has verified

implementation of the corrective actions.

This item is considered closed.

(Closed) 456/87057-LL:

Turbine Trip and Subsequent Reactor Trip During

Monthly Turbine Valve Cycle Surveillance.

This event was previously

j

discussed in Inspecticn Report 456/87044; 457/87045.

The cause of this

event is still not known. Several successful valve cycle surveillances

4

had been perfomed subsequent to this event. This item is considered

,

closed.

If another event occurs, another review will be perforned.

(Closed) 456/87063-L1:

Two Inoperable Non-Accessible VA Filter Plenums

J

Due to Misalignment. The subject of this supplement to LER 87063 was

previously reviewed in NRC Inspection Report 456/88011; 457/88013, for

which a Notice of Violation was issued.

This item is considered closed

Train A Control Room Radiation Monitoring

i

I

Tno~perable Due to Noisy Pressure Switches. On January 8,1988, at

9:50 a.m.; on January 11, 1988, at 12:30 a.m.; and on January 12, 1988,

at 10:24 a.m.; spikes occurred on control room intake radiation monitors

OPR32J and OPR31J. The spikes resulted in the OA train of control room

l

ventilation (VC) switching to the makeup rnode.

The spikes were determined

to be spurious, and the monitors were returned to service. The events

resulted from the operating characteristics of the trcnitors' pressure

j

switches. During modulation of the monitor's flow control valves, the

-

switches emit electrical ncise spikes which ultimately are interpreted

as radiation-propagated current pulses by the monitor's preamplifier

J

circuitry.

Action to prevent recurrence includos adding noise attenuating

filters to the pressure switch circuitry to eliminate the false trips,

The inspector's review of the event verified that the licensee's actions

a

J

are adequate.

This item is considered closed.

actuation. The licensee's corrective action was to return the system to

.

normal and to increase the pulse tima interval from five to ten minutes

as noted in the vendor manual. The inspector has no further concerns.

This item is considered closed.

(Closed) 456/88003-LL:

Loss of Pulses to Fuel Handling Incident Monitor

ORT-AR056 for Unknown Reasons. At 7:10 p.m. on January 13, 1988,

radiation monitor ORT-AR056 went into the interlock mode due to a loss

of pulses. The train B fuel handling charcoal booster fan started,

and the charcoal filter was placed in service.

The failure of monitor

ORT-AR056 was verified to be spurious, the fuel handling charcoal booster

fan was shut down, and the system was returned to normal.

The root cause

of the event is unknown. The inmediate corrective action was to determine

that the source of the actuation was spurious in nature and not due to

actual radioactivity. There have been no further spurious loss-of-pulse

events concerning ORT-AR056. The licensee's actions for this event are

adequate. This item is considered closed.

(Closed) 457/8800_3-LL:

Inadvertent loss of Power to Instrument Bus 212

Resulting in a Reactor Trip Oue to Personnel Error.

At 10:52 a.m. on

January 31, 1988, with Unit 2 in Mode 5, a reactor trip signal was

received as a result of removing power from instrurrent bus 212.

The bus

is the control power source for source and intermediate range channels.

The event was caused by contractor personnel working in the area. The

contractors were preparing the inverter cabinet for the bus for painting

and inadvertently tripped a breaker on the inverter.

Power to bus 212 was

restored from its constant voltage transformer, and the painters were

told to discontinue work on the inverter cabinet. The inspector has no

further concerns with this item; this item is considered closed.

(Closed) 457/88004-LL: Undervoltage Start of 2A Diesel Generator (DG)

Due to Operator Error. At 10:27 a.m. on January 29, 1988, the Unit 2 2A

DG auto started. The auto start resulted from an undervoltage signal

which was generated by the inadvertent removal of the bus 241 potential

transfomer (PT) fuses by an equipment operator (EO), instead of the

intended bus 241 system auxiliary transformer (SAT) feed PT fuses. A

contributing cause to this event was a comunication problem between the

center desk nuclear station operator (NS0) and the E0. The information

sheet used, which will be revised, did not reflect the actual equiptrent

field norrenclature.

The event has been reviewed with the E0 involved,

who has received additional training, including a walk-through with a

training indructor and a licensed foreman to verify his technical

knowledge.

There have been no subsequent DG auto starts of this type.

The licensee is evaluating this event with emphasis on how to prevent

further personnel errors of this type.

This item is considered closed.

1A Diesel Generator (DG) Start on a Safety

Injection Signal Instead of an Undervoltage Signal During Testing Due to

Operator Miscornmunication. During the perfomance of IBwVS 8.1.1.2.f-13

(a DG sequencing surveillance), on February 4,1988, due to a

miscorrunicatien between two NS0s, the diesel auto started on a safety

.

was successfully completed at 2:12 a.m. on February 4,1988.

The fiS0s

involved were counselled on the event. The inspector has no further

concerns relative to this event.

This item is considered closed.

(Closed) 457/88006-LL:

Inadvertent Start of the Unit 2 Auxiliary

Feedwater (AFW) Pump Due to Personnel Error.

The start of the 2A AFW

pump was caused by the misuse of the volt-ohmeter used to conect data

for surveillance 2 Bw05 3.2.1-941, "Unit 2 ESFAS Instrumentation Slave

Relay) Surveillance (Train A Auxiliary Feedwater Actuation, Lolo SG Level

-K633 ," which was being performed at the time of the pump starts.

The

,

surveillance is nos intended to start the 2A AFW pump. The operator

misuse of the volt-ohmeter was considered a violation and is discussed

,

(Closed) 456/88008-LL:

Reactor Coolant System Leakage Due to Broken

Relief Valve Disc Pin.

On March 25, 1988 and March 27, 1988, with the

unit in Mode 4, the Unit I fiS0s identified that unidentified leakage

was in excess of the one gallon per minute (GPM) Technical Specification

limit. Licensee investigations identified that the leakage on March 25,

1988 was due to valve IRH8729A; although locked in the closed position

the valve's disc was off its closed seat. The March 27, 1988 leak was

due to leaking residual heat removal (RHR) suction relief valves,

fluclear Work Requests were written, and the valves were repaired or

recalibrated. The Itcensee corrective actions were appropriate for

'

the two events. The inspector has no further concerns.

This item is

'

considered closed.

(Closed) 457/88011-LL:

Reactor Shutdown Required as a Result of Valve

25188098 Declared Inoperable Due to fion-Environmentally Qualified Motor.

At 6:00 p.m. on June 7, 1988, Westinghouse Electric Company notified

Braidwood Station that no environmental qualification (EQ) documents

could be found for the motor operator installed on containment isolation

3

valve 25!88098. The valve was declared incperable, and the Limiting

Condition for Operation (LCO) of Technical Specification 3.6.3

,

i

(containtrent isolation valve operability) was entered. A plant shutdown

l

was initiated, and the unqualified motor was removed and replaced with

one that was EQ qualified. An Unusual Event was declared.

The

declaration time of the Unusual Event was not considered by the f1RC to be

in corpliance with the licensee's General Station Emergency Plan (GSEP),

i

A flotice of Violation was issued for a violation of the GSEP program,

j

Part of the licensee's corrective action for this event has been to

review all remaining open Westinghouse Field Deviation Reports for

,

l

similar problems.

The inspector has determined the licensee's actions

to be adequate and has no further concerns.

This item is considered

current readings on the relay. Opening of the shorting switch caused

,

.

a voltage spike and actuated the instantaneous overcurrent protective

relay, which ultimately resulted in a turbine trip / reactor trip. An AFW

a

pump also auto started on Lolo steam generator (SG) level caused by the

i

resultant shrink in the SG 1evel.

The root cause of this event was

!

attributed to a defective current test switch on the B phase of the CO-7

overcurrent relay.

The defective switch was replaced and tested.

The

inspector has no further concerns.

This item is considered closed.

(Closed) 457/88013-LL: Low Steam Generator Level Results in Reactor

'

Trip Due to Inadequate Procedure Guidance.

On June 21, 1988, at

'

1:07 a.m., a reactor trip occurred due to a Lo-Lo steam generator level

caused by insufficient feedwater (FW) flow.

The low FW flow was due

to an out-of-service (005) that isolated FW flow to the SG. On June 20,

1988, at 11:45 p.m., the Station Control Room Engineer (SCRE) had

,

j

authorized clearance of the 005, but a high priority was not given to

its clearance and to establishing a normal FW lineup.

Consequently,

'

j

when the reactor startup on June 21, 1988 was at the point of adding

)

heat, the insufficient flow caused the reactor trip.

Personnel

performing the reactor startup were not aware of the FW system lineup.

'

l

The licensee's corrective actions to prevent recurrence are to:

(1) revise procedures to verify proper FW system lineup prior to

a

increasing power from the point of adding heat; (2) review the event

i

with the personnel involved and errphasize the need for awareness of

i

system configuration; and (3) issue a memo to the operating staff

]

describing the evert and actions to prevent recurrence.

The inspector

l

has no further concerns.

This item is considered closed.

(Closed) 457/88014-LL:

Reactor Trip Due to Low Water Level Caused by

i

Erretic Operation of Main Water (sic) Regulating Valve.

On June 22, 1988,

j

at 12:29 a.m., a reactor trip occurred due to a Lo-Lo steam generator

1

level.

The trip was due to a feedwater transient initiated during a

normal switchover f*om the feedwater regulating) bypass valves (FWRBPVs)

'

l

to the main feedwater regulating valves (MFWRVs for SG level control.

During the transfer from the FWRBPV to the MFWRV for the 28 SG, an MFWRV

1

malfunction caused the 2B SG level to reach its Hi-Hi setpoint, which

actuated a turbine trip, feedwater isolation, and feed pump trip.

]

Approximately 18 seconds later, the 20 SG 1evel reached tt.e Lo-lo level

-

setpoint, which resulted in a reactor trip.

The root cause of the event

.

was the erratic operation of the 2B MFWRV.

Plant conditions were

]

restored to a normal status by 12:22 a.m.

The 2B MFWRV was repaired and

l

returned to service.

The inspector's review of this event identified

j

that the licensee's actions were prompt and adequate in nature.

(Closed) 457/88016-LL: Unit 2 Reactor Trip on Lo-Lo 2B Steam Generator

Level. On June 24, T988, at 12:21 p.m. , a reactor trip occurred due

j

to a Lo-Lo level in the 2B SG. The cause of the trip was a failed

'

open heater drain tank (HDT) makeup valve, which caused the condensate

booster (CB) pump discharge pressure to decrease.

The CB pump discharge

!

pressure decrease resulted in a loss of feedwater flow and subsequent

[

decreasing SG levels.

The trip occurred about one minute after the loss

i

of FW flow.

The imediate corrective actions were to recover SG levels

and to establish stable conditions.

The HDT makeup valve has been

!

repaired. The licensee performed an FW system walkdown to ensure that no

,

more abnormalities existed in the system.

The inspector has no further

concerns. This LER is considered closed.

In addition to the foregoing, the inspector reviewed the licensee's

Deviation Reports (DVRs) generated during the inspection period. This

l

was done in an effort to monitor the conditions related to plant or

!

personnel performance, potential trends, etc.

DVRs were also reviewed

I

to ensure that they were generated appropriately and dispositioned in

Through observations by the inspectors and information provided by

l

licensee personnel, lake status reports were submitted weekly.

,

)

Throughout the inspection period, operation of the station was not

l

'

1

affected by lake conditions.

The Kankakee River (the normal makeup

'

source) went below the minimum flow for makeup of 442 cubic feet per

second on several occasions.

Intennittently, the rakeup purps could be

!

run. When pumping from the river was insufficient to keep up with

l

,

evaporation and normal losses, the licensee chose to take makeup water

[

,

J

from nearby licensee-cwned strip mine lakes.

This was done after

Ccmonwealth Edison signed an agreement with local officials to provide

makeup water if local wells are affected and drilled 22 rnonitoring wells.

!

At the cnd of the inspection period, local rainfall had created

f

sufficient river flow for two makeup purps to be run from the Kankakee

!

River, and the licensee continued to supplement cooling lake makeup with

l

water from the strip mine lakes.

The licensee plans to pump cnly

two-thirds of the water from the strip mine lakes and has a plan for

!

restoration of the strip mine lakes to preserve wildlife habitat.
