Plant Status-At the start of the inspection period, the plant was operating at 100X power with an unusually high equipment drain (EDR) flow rate.
On October 26, power was reduced to approximately 10X to allow a drywell entry for locating the source of the high EDR flow.
Two.drain valves on the reactor water cleanup (RWCU) line from the "A" recirculation loop were found to. be about'/8 to 1/4 turn open.
When these were closed, EDR flow dropped to its normal rate of about
GPM.
Reactor power was returned to 100X by October 28.
The reactor was again shut down on the night of October 31 due to a condenser tube leak.
The leak was repaired and the reactor was restarted on the evening.of November 3.
During the 1000 psi
'alkdown of the drywell on the morning of November 4, a reactor coolant pressure boundary weld was found to be leaking (see paragraph 4).
The plant was shut down again -and the weld was repaired, as well as three others that were possible future candidates for vibration induced fatigue.
failure.
The reactor was restarted on November 7 and 100X power was achieved on November 9.
On the morning of November 19, the plant scrammed from 100X power due failure of the feed flow summer in the'eedwater Level Control System (see paragraph'5).
An Unusual Event was declared when reactor vessel level subsequently decreased to the Level
setpoint.
The.plant was taken to cold shutdown on the morning of November 20.
The plant was restarted on November 22, and 100X power was

Previousl Identified NRC Ins ection Items 92701 92702 The inspectors reviewed records, interviewed personnel, and inspected plant conditions relative to licensee actions on previously identified inspection findings, as follows:.
a.
. Closed Violation 397 91-12-05
Failure-'to Fo low mer enc Diesel Generator EDG 0 eratin Procedure The licensee had incorporated guidance into the EDG operating procedure for action to take in the event of an excessively low level in the generator bearing oil. It specified that emergency action be taken (when the EDG was operating in a non-emergency condition) to secure the unit in the event of low oil level.
The
.action that had been intended by the Technical staff person who initiated the procedure change was an immediate tripping of the EDG.
However, a low level condition was experienced by the operators and the EDG was not tripped.
This was cited as a violation of the operating procedure, which was required by Technical Specifications.
The'icensee revised Plant Procedures Hanual (PPH) 2.7.2, the EDG operating procedure, and PPH 7.4.8. 1. 1.2. 1, the EDG monthly survei.llance procedure, to provide specific;guidance to trip the EDG when it is running in a non-emergency condition and a low bearing oil level condition has developed.
This was also discussed in the Operations Department Night Order book, which was required reading for all of the Operations staff.
This item is closed.
b.
Closed Violation 397 91-18-01:
Second Verification Not Provided on Certain Clearance Orders as Re uired C.
The inspector had identified seven different clearance orders on safety-related components that did not have required independent verifications accomplished.
The clearance order procedure was required by Technical Specifications.
r The licensee revised clearance order procedures PPH 1.3.8A and PPH 1.3.8C.
This revision included an addition to the Shift Hanager's responsibilities to specify whether independent verification is required on any given clearance order, both when the clearance order is being hung and when it is being cleared.
This item is closed.
Closed Unresolved Item 397 91-35-05
Performin Traversin Incore Probe TIP Normalization after Local Power Ran e Honitor LPRH Calibration Instead o
Prior to LPRH Calibration The inspector had identified a potential problem with performance of the TIP normalization.
It appeared that the normalization of the TIPs was being accomplished after the actual calibration of the
-3-LPRHs, despite a Technical"Specification (TS) requirement to perform the normalization p'rior to this calibration.
Further review and discussions with reactor engineers revealed that the Powerplex system,'nstalled in.1986, performs the normalization internal to the, system prior to.'the calibration, after receiving all TIP data from all LPRM locations.'herefore the inspector determined that the.licensee wa's in compliance with the Technical Specifications.'owever, the inspector noted that the procedure that governs this process, PPM 9.3.3;
"LPRM Calibration",
had been'n error from 1986 until 1989.
Specifically, PPM 9.3.3 had directed that the five TIPs be run through the reference locations first, and that TIP normali-zation constants then be derived before *running the TIPs through all the plumbed locations.
This was in error, since Powerplex takes all the TIP data from all the plumbed locations as a batch, and does its own internal normalization prior to LPRM, calibration, as described above.
Since Powerplex functions in this way, and apparently has since it was first installed in 1986, it was apparent to the inspec-tor that the reactor engineers had not been following PPM 9.3.3 until it was revised in 1989 to reflect how Powerplex really functions.
Since PPH 9.3.3 is required by TS and Regulatory Guide 1.33, failure to follow this procedure is an apparent violation of TS requirements.
However, since the criteria for a non-cited violation from the NRC Enforcement Policy were satisfied, this violation will not be cited (91-39-01, Closed).
This item is closed.
Leakin Socket Weld in Reactor Coolant Pressure Boundar On October 31, the licensee shut down the reactor due to high reactor water conductivity resulting from an apparent condenser tube leak.
The leak was repaired and the reactor was restarted on November 3.
During the 1000 psia walkdown of the drywell on the morning of November 4, plant operators discovered a leaking socket weld in the reactor coolant pressure boundary.
The weld was located on a 3/4-inch drain line connected to the 12-inch Train "A" shutdown cooling return piping to the recirculation loop.
The licensee shut down the unit pursuant to Tech-nical Specifications requirements.
Several similar socket weld failures have been experienced in the past at WNP-2.
They have typically been the result of one or both drain valves being located downstream of an elbow in the drain piping, creating a
large moment arm.
This, coupled with high localized vibration, leads to fatigue cracking from the outside in.
However, the licensee discovered upon further examination that the initiator of the November 4 failure was a construction defect in the weld (lack of fusion), causing it to crack from the inside out.
Such defects are difficult, if not impossible, to detect in this type of weld.
The ASME Code requires only dye penetrant testing (PT)
and visual exams for this type of weld, which are effective only for detecting cracks in the outer surface of the weld.
Ultrasonic testing or radiography, while effective for the interior of the weld, would be inconclusive in this application due to the geometry=of the wel ~
t Rj
The licensee had previously classified all drain line socket welds in direct communication with the reactor coolant pressure boundary according to their susceptibility to a small break LOCA.
Locations with a large moment arm and high vibration were considered highly susceptible.
Locations with only one of 'these attributes were considered to be of medium susceptibility, and locations with neither of these attributes were considered to be of low susceptibility.
Host of these welds had.PT performed on them about a year ago when a similar problem had arisen.
PT was again performed during. the ]991 refueling outage.
The particular weld that had failed on November 4 had shown no indications on both occasions.
Host of the h'ighly susceptible connections were upgraded to a stronger weld configuration during the 1991 refueling outage.
This one, however, had=been deferred to the 1992 refueling outage because of poor accessibility for repair.
Four locations left from the 1991 refueling outage were classified as highly susceptible to a small break LOCA.'he licensee elected to provide temporary remedies fdr these locations during the early November outage, and provide'
permanent solution during the 1992 refueling
,outage.
In three of the four cases these temporary solutions involved removal of the va1ves from the drain line {i.e., replacing the drain line-with a welded.nipple), thus eliminating the large moment arm.
In one location, another weld pass was completed on the socket weld.
The me'dium susceptibility locations will also be worked during the 1992 refueling outage.
The licensee restarted the unit on the morning of November 7.
While no violations or deviations were identified, the licensee was encouraged at the exit meeting to take steps to permanently rectify the recurring problem with socket weld failures.
Feedwater Transient with Resultant Reactor Scram and En ineered Safet Feature ESF Actuations At about 7:45 a.m.
on November 19, 1991, WNP-2 experienced a rapid reactor pressure vessel (RPV) level increase over a period of several
.
seconds.
. The increase ended when RPV level reached the Level 8 setpoint of +54.5".
This caused a trip of both feedwater pumps, and a turbine trip with a resultant reactor scram.
RPV level subsequently decreased over about a 45-second period until it reached the Level 2 setpoint of about -50".
A number of ESF actuations occurred at Level 2.
The Division III emergency diesel generator (EDG) started, the high pressure
.
pump started, and non-essential loads were shed from the emergency buses.
A number of nuclear steam supply shutoff system-
{NS") isolations also occurred, including a main steam isolation valve (MSIV) closure and an isolation of reactor closed cooling (RCC) water to the drywell.
All of these actuations were according to design.
Reactor core isolation cooling (RCIC) was started manually by the operators when RPV level was decreasing through about -20".
The HSIV isolation complicated the event,'ecessitating RPV pressure and level control using RCIC and safety relief valves (SRVs).
An Unusual Event was declared when RPV level decreased to the Level 2 setpoint.
The Emergency Operating Procedures (EOPs)
were entered when RPV level decreased through
f, 1'i i
I t~
I
!
+13",
as required.
The operators responded well to the event, following their EOPs closely.
Loss of RCC to the drywell caused drywell temper-ature to increase to about 139 degrees, constituting another EOP entry condition, and resulting in a-drywell pressure increase.
Another ESF actuation of HPCS occurred at a drywell pressure of about 1.34 psid.
HPCS was quickly secured.
RPV pressure and level were eventually stabilized and pressure was equalized around the HSIVs, allowing them to be opened.
This allowed a condensate booster pump and bypass valves to be used for RPV pressure and level control.
The Unusual Event and the EOPs were exited when plant conditions were stabilized in Hode 3 and RPV pressure and level were being controlled by a booster pump and the bypass valves.
The decision was made to go to cold shutdown (Hode,4) later that day.
The feedwater transient was caused by the failure of a feedwater summer in the feedwater level control system (FLCS).
The FLCS compares feedwater flow, steam flow, and actual RPV level, and adjusts feedwater flow accordingly by controlling feed pump speed.
The feedwater summer adds the feedwater flow in both feedwater lines and inputs this value to the level controller.
A one-amp fuse in the. summer card blew, causing the summer output to go a value of less than z'ero.
This was Interpreted by the level controller as zero feedwater flow, and caused the feed flow/steam flow mismatch to go to maximum.
The level controller rapidly ramped up the speed of both feedwater pumps, increasing feedwater flow to.
the maximum, and all the events depicted above ensued.
A similar event occurred in Harch 1987.
The same fuse had blown at that time, although it was then a 1/4-amp fuse.
The licensee decided follow-ing the 1987 event to upgrade the fuse size to one amp, since the 1/4-amp size was unduly conservative and increased the risk of a significant plant transient.
The blown fuse in November 1991 was considered to have been valid, resulting from a failing capacitor in the summer card.
The capacitor was replaced, and the card behaved normally.
However, the licensee elected to replace the whole summer card in the FLCS.
The 1987 event was also complicated by the shedding of electrical loads which occurs at Level 2 (>-50").
This included shedding of turbige service water '(TSW)
and RCC, and much of the normal plant lighting.
The TSW system is the principal cooling water supply for many plant components, and must be restored promptly to avoid equipment damage.
Loss of RCC results in heatup of the primary containment, requiring prompt operator 'action to avoid another isolation and ECCS actuation at less than 2 psig in the containment, after which RCC cannot be restored.
This distraction of the operators and the need to move about the plant and perform various evolutions without normal lighting additionally complicates followup to an event.
The LER which addressed the Harch 1987 event included a licensee commitment to assess the advisability of modifying the load shedding scheme to avoid unnecessary complications at Level 2 (a condition which is not unusual following some loss-of-feed events).
During discussions following this event, plant management stated that TSW had been modified during the 1990 refueling outage to shed only if a loss of offsite power occurs, and that a design change addressing the RCC issue was budgeted for the 1994 refueling outage (subject to emergent work which might compete for budget resources).

]I l
The inspectors attended the debriefing of involved control room operators.
and the restart Plant Operations Committee (POC) meeting.
The inspectors concluded that the licensee had thoroughly investigated the various aspects of the transient.
The inspectors found the performance of the control room operators in response to the transient to be exemplary, and so informed the Plant Manager.
The plant was restarted on November 22.
No violations or deviations were identified.

General Plant E ui ment Conditions.
Plant equipment was observed for indications of system, leakage, improper lubrica-.
tion,'or other 'conditions that could prevent the system from fulfillingits functional requirements.
Annunciators were observed to ascertain their status and operability.
The inspector toured the reactor building with the Plant Manager on November 7 and pointed out to him components or equipment with substandard material condition.
This included the following:
A heating steam relief valve with a sizable body-,to-bonnet leak at the 471'evel.
The leakage was directed into a collection funnel and drained away through a hose that extended to the 441'evel, through the main.corridor of the plant and into a floor drain in the turbine building.
- Notable leakage from a discharge check valve in Train "B" of the reactor closed cooling (RCC) water system.
The shaft seal was leaking heavily and the leakage was directed via a hose to a floor drain.
The inspector noted that this indicated that the RCC system may be further
'egrading.
It was already lined up using'ertain of its pumps and heat exchangers to maximize cooling capacity, since it could not maintain low enough temperatures using all pump/heat exchanger combinations.
-Oil leakage from the "B" standby liquid control (SLC)
pump motor.
In addition, water leakage was observed from the
"A" SLC pump stuffing box.
It appeared that there
'as a leak of standby service water somewhere on, or under, the CAC skid.
Earlier in the week, the puddles had been large enough to form. a pool around the CAC skid.
A mop and bucket had been placed nearby with a sign indi-cating the existence of a personnel safety hazard.
Although none of the material deficiencies depicted above appeared to impact the operability of any safety related equipment, the inspector expressed his concern about the appearance and material condition of WNP-2 in general as evidenced by these specific examples.
By the end of the inspection period, the licensee had taken steps to correct most of these deficiencies, and had identified for correction the rest of them.

Plant conditions and material/equipment storage were observed to determine the general state of clean-liness and housekeeping.
Housekeeping
.in the radiologically controlled area was evaluated with respect to controlling the spread of surface and airborne contamination.
The inspectors noted on several occasions duping the inspection period that plant housekeeping was poor.
The inspectors found loose paper trash, unattended radwaste, standing water, ladders and loose hand carts resting against piping, and oil leaks throughout the reactor building.
These deficiencies were brought to the attention of licensee management and were cor-rected.
The Plant Hanager stated that housekeeping conditions
'were not up to his expectations and that the sensitivity of equipment operators and floor'oordinators would be increased.

Plant Maintenance 62703 During the inspection period, the inspector observed and reviewed documentation associated with maintenance and problem investigation activities to verify compliance with regulatory requirements and with administrative and maintenance procedures, required QA/QC involvement, proper use of clearance tags, proper equipment alignment and use of jumpers, personnel qualifications, and proper retesting.
The inspector verified that reportability for these activities was correct.
The inspector witnessed portions of the following maintenance activities:
Descri tion ates Performed AR-6030, RPS MG Set BeaÃng Replacement and Testing November
AR-5549, Repair of RHR-FCV-64B December
P During the testing portion of the work on the RPS MG set the inspector noted that, although the work was generally performed in a deliberate step-by-step manner with good participation from the maintenance engineer, minor deficiencies existed.
AR-6030 stated that no fire impairment checklist or permit was necessary for the work.
However, the fire door for the RPS HG set room was propped open to allow for the passage 'of cables for testing equipment.
The fire impairment checklist was'nevertheless obtained, despite the improper procedural guidance.
This was brought to the attention of the maintenance engineer, and the procedure was revised to indicate that a fire impairment checklist was required.
The inspector also noted that AR-6030 directed the user to "periodically monitor bearing vibration and temperature levels" for the MG set.
This was to preclude destruction of the HG set by operating it at excessive vibration and temperature for an extended period of time.
The mechanic stated that he interpreted this statement to mean that the bearing vibration and temperature should be checked at hourly intervals when data required for the procedure were to be taken.
The inspector discussed this observation with, the maintenance engineer, who stated that the intent of this procedural direction was for the mechanic to take the periodic readings approximately every five minutes, and then directed the mechanic to begin taking these periodic readings.
The first reading taken at this time showed excessive vibration of the HG set and indicated
.that it should be immediately secured.
However, before the mechanic could take action, the HG set tripped automaticall ~
'
'
Although the reactor protection system (RPS)
HG set is not safety related, the deficiencies noted above indicat'e the need to ensure that the expectations of management and engineering are properly commu'nicated to,maintenance personnel performing the work.
During the repair of RHR-FCV-64B, the inspector noted that the mainte-nance work request (HWR) directed the repair of the wrong lead within the
. torque-switch compartment (lead BVID-9119 versus the correct wire, BRHR-9036).
The error was found at the worksite, a procedure change was initiated, and the work was performed
=in accordance with the HWR.
Although the work was performed correctly, this incident emphasized the need for att'ention to detail in the development of work procedures.
No violations or deviations were identified.
eview of Verification and Validation Pro ram 42700
'
The inspector reviewed the licensee's Verification and Validation (V&V)
program to ascertain the contribution of the V8V program to the quality of'lant Operations procedures.
The V8V program at WNP-2 consists of a twofold process.
The verification process has thorough checklists to research the applicable requirements and as-built drawings.
The valida-tion process can consist of walkthrough in the plant, operation in the simulator, or a tabletop discussion.
The inspector determined that decisions appeared to have been appropriate the type of validation to perform for specific procedures.
'I The inspector noted that a large percentage of the V&V effort was dedicated to surveillance procedures (Volume 7)
and annunciator/abnormal operating procedures.
There are a large number of these procedures and
.each was to be V8V'd and would be subject to a-subsequent biennial V&V.
Other procedures contained in different volumes of the PPHs were V8V'd when time permitted.
The inspector expressed concern that Volume
(system operating)
procedures required to be invoked when using the EOPs were not prioritized as being among the first procedures to be V&V'd.
'he inspector had noted previously, as discussed in NRC Inspection Report
No. 91-28, that PPHs 2.3.3A/B had not been V8V'd despite being invoked by
, the EOPs.
The inspector also noted several errors in those two PPHs which were documented in NRC Inspection Report No. 91-28.
The inspec-tor's subsequent review of the V&V program revealed that five other procedures (contained in Volumes 2 and 12 of the PPHs) called out by the EOPs apparently had not rec'eived a V&V.
These procedures are listed as follows:
