. Licensee Action on Previous Inspection Findings This area was not inspecteu in this repor . Unresolved Items Unresolved items are matters which more information is required to determine whether they are acceptable or may result in violation New unresolved items identified during this inspection are discussed in paragraph / Review of Plant Operations This inspection period commenced with the plant in Itode I, Power Operations, At approximately 7:46 p.m., on flarch 27, the plant experienced a runback from 94% to 73% full power due to a loss of "C" reactor coolant pump (RCP)

(see section 7.b of this report for details). The plant continued power

. .

.

operation until 5:56 p.m. on llarch 30, at which time a reactor trip occurred due to a spurious reactor coolant pumping power monitor (RCPPit) trip (see section 7.a of this report for details). On April 1, the USilRC granted the licensee permission to bypass the RCPPfl's and proceed with !! ode I, Power Operations, at a reduced power level of 75% full power. The plant entered Mode I at 6:31 a.m. on April 2, and continued in that mode until April On this date, the USNRC approved plant operation up to 90% full power with the RCPPit's bypassed at which time the licensee increased to 90% and con-tinued to operate at this power level for the remainder of this inspection perio The authorization that the licensee received on April 1 to allow plant operation up to 75% full power was forwarded to the NRC as a " Request for Interim Emergency Authorization" and involved a change to the facility Technical Specifications (TS). Review of the onsite review committee (Plant Review Committee [PRC]) meeting minutes for PRC meetings conducted the week of March 29 to April 2 do not provide evidence that the proposed change was reviewed by the PRC as required by TS 6.5.1.6.c. Discussions with licensee personnel indicate that the issue was reviewed by the PRC members but that the issue was not documented. These discussions also ir.dicate that while the licensee appears to have an effective system to assure that proposed TS changes are reviewed by the PRC, they do not have a system to assure that emergency TS or license changes, which may occur at any time of the day or night, are forwarded to the PRC. A similar problem exists with the licensee's offsite review committee, the Nuclear General Review Committee (NGRC). The NGRC is required by TS 6.5.2.8.d to also review proposed TS and license changes but the licensee's system does not provide for review of the emergency change The licensee committed to review their methods of providing emergency TS and licensee change proposals to both the PRC and NGRC and develop a system for accomplishing same. In addition the licensee committed to determine if a TS change will be requested to clairfy the proposed change requirement Unresolved Item (302/82-09-01): Development a method to assure that emer-gency TS and licensee changes are forwarded to the PRC and NGRC for review, Shift Logs and Facility Records The inspector reviewed the records listed below and discussed various entries with operations personnel to verify compliance with TS and the licensee's administrative procedure Shift Supervisor's Log;

-

Reactor Operator's Log;

-

Equipment Out-of-Service Log;

-

Shift Relief Checklist;

- Contrc' Center Status Board;

-

Auxiliary Building Operator's Log;

Short Term Instruction In addition to these record reviews, the inspector independently verified selected clearance order tagout During a review of the Shift Supervisor's Log on April 20 and 21, the inspector noted that four Engineered Safeguards (ES) train "B" pumps (RWP-3B, BSP-18, DHP-1B, and DCP-1B) were taken out of service for preventative maintenance at 6:30 a.m. on April 20, and returned to service between 4:05 a.m. to 6:41 a.m. on April 21. A review of the clearance order for this maintenance indicated that the last tag was removed from these pump at 3:10 p.m. on April 20. The inspector queried the licensee as to why the pumps were not started for the purpose of declaring the pumps operable as soon as possible subsequent to the maintenance even though Technical Specifications allow a maximum time of 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> for the equipment to be out of service. The licensee stated it is their normal operating philosophy to return equipment to service as soon as possible subsequent to maintenance, but due to a communication error between shifts, the pump remained technically out-of-service awaiting the performance of additional pump inspection The inspectors will continue to monitor this issue during subsequent ins pection b. Facility Tours and Observations Throughout the inspection period, facility tours were conducted to observe operations and maintenance activities in progress. Some operations and maintenance activity observations were conducted during backshift The facility tours and observations encompassed the following areas:

-

Security Perimeter Fence;

!!o discrepancies were identified in this are (7) Surveillance Testing - Surveillance testing was observed to verify that:

-

approved procedures were being used; 4 - qualified personnel were conducting the tests;

-

testing was adequate to verify equipment operability;

-

calibrated equipment, as required, were utilized; and

-

Technical Specification requirements were followe The following tests were observed:

-

SP-130, Engineered Safeguards Monthly Functional Test

(section 6.2 for post maintenance testing);

'

-

SP-113, Power Range fluclear Instrumentation Calibration (Channel B);

- SP-312, Heat Balance Calculation; ,

-

-

SP-216, Sample Line Leak Rate Test (procedure review only);

-

PT-302, flain Steam Rupture flatrix Time Delay Relay Test (completed test results); and

-

SP-154, Functional Testing and Calibration of the Triaxial Time-History Accelographs and Triaxial Seismic Switc As a result of these reviews, the following violation was identi-fied: ,

During observation of SP-154, the inspector noted that this procedure was only a general procedure which directed the. actual .

functional testing and calibration to be performed by the vendor

'

by use of the vendor's procedure. SP-154 only provided for !

verification and documentation of this action. A review of the

,

vendor procedure and discussion with the plant review committed t (PRC) chairman indicated that the vendor's procedure had not been ;

reviewed by the PRC and approved by the fluclear Plant 11anager .

prior to implementatio .

Technical Specification (TS) 6.8.2 requires each procedure ;

required by TS 6.8.1 and Regulatory Guide 1.33 to be reviewed by '

the PRC and approved by the fluclear Plant fianager prior to imple-menta tion. Regulatory Guide 1.33 requires procedure for each surveillance test and calibration listed in the TS. TS 4.3.3. requires functional testing and channel calibration of the tri-axial time-history accelographs and the triaxial seismic switc Contrary to the above, the vendor procedure used to perform the l calibration of the time-history accelographs and triaxial seismic switch was not reviewed by the PRC and approved by the fluclear Plant flanager prior to implementation. This is a violatio . .

Violation (302/82-09-02): Failure of PRC to review and Nuclear Plant flanager to approve vendor calibration procedure prior to implementatio (8) llaintenance Activities - The inspector observed maintenance activities to verify that:

-

Correct equipment clearance were in effect;

-

Work Requests (WR's), Radiation Work Permits (RWP's), and Fire Prevention Work Permits, as required, were issued and being followed;

-

Quality control personnel were available for inspection activities as required; and

-

Technical Specification requirements were being followe The following maintenance activities were observed:

-

Replacement of failed relay in ES actuation channel 2A;

-

Inspection and Lubrication of decay heat closed cycle cooling water pump (DC)-1B in accordance with P!1-117 and PM-133;

-

Repair and calibration of waste disposal (WD) pressure indicators WDS-17-PI, WD-18-PI and WD-19-PI; and

-

MP-149, Check Valve Cap Removal and Reinstallation and associated work package review on repair of core flood valve (CFV)- As a result of these observations, the following item was identi-fied:

During a review of the work package associated with CFV-1 repair, the inspector identified several questionable areas that need to be addresse (a) A Crane Valve information book that was not under document control was used to support a procedure change to MP-149 to allow a torque limit of 650 f t-lbs on the hinge pin nu Discussions with licensee personnel indicate that a Crane Valve representative would neither verify the applicability of the information book to CFV-1 or advise exceeding and upper torque limit of 545 f t-lb (b) As a result of the increased torque on the hing pin nut, the .

cotter keyway became misaligned preventing insertion of the cotter key. A flodification Approval Record (itAR) was pre-pared to drill a new hole but could not be accomplished, A decision was then made to " stake" the hinge pin as a substi-tute method of securing the hinge pin nut. this was accom-plished by a procedure change to MP-149 in lieu of preparing a 11AR as required by CP-114, Procedure for Preparation of Permanent and Temporary Modification . .

.

The inspector discussed these issues with the licensee and was infonned that the licensee's Quality Programs Department was preparing a Quality Program Surveillance Report (QPSR) on this activity and included similar finding The inspector reviewed QPSR 82-VAH-05 and concurs that these findings were essentially the same as the inspector's. A followup on QPSR 82-VAH-05 will be conducted to verify proper response and corrective actions on the noted deficiencie Inspector Followup Item (302/82-09-03): Review licensee's response and corrective actions on QPSR 82-VAH-05 finding . Review of Licensee Event Report and Non-Conforming Operations Reports (NCOR's) The inspector reviewed Licensee Event Reports (LER's) to verify that:

- The report accurately describe the events;

- The safety significance is as reported;

- The report satisfies requirements with respect to information provided and timing of submittal;

- Corrective action is appropriate; and,

-

Action has been take LER's 82-12, 82-13, 82-15, 82-16, 82-17, 82-20, 82-21, 82-22, 82-23, 82-24, 82-25, 82-26, and 82-27 were reviewed. The review identified the following items:

(1) LER 82-16 reported the failure to perform an adequate 10 CFR Part 50.59 review of a system modification prior to completing the modification. This issue is discussed in detail in paragraph of this report and was identified by the inspector as a violatio (2) LER 82-27 reported the loss of the "C" Reactor Coolant Pump (RCP)

and subsequent plant runback to approximately 72% of full powe This issue is discussed in detail in paragraph 7b of this repor The inspector reviewed NCOR's to verify the following:

-

Compliance with Technical Specification;

- Corrective actions as identified in the reports of during sub-sequent reviews have been accomplished or are being pursued for completion;

-

Generic items are identified and reported as required by 10 CFR Part 21; and

-

Items are reported as required by the Technical Specification .

' At 5:56 p.m. on ihrch 30, a plant trip fran approximately 75% full power occurred due to a trip in the reactor coolant pump power monitor (RCPPil) system. the RCPPM trip was caused hy a peturbation on the 6900 volt reactor coolant pump power supply bus which was, in turn, caused by a perturbation on the 230 kilovolt (kV) grid. The 230 kV grid perturbation occurred when a downline power plant was connected to the grid.

.

. The resident inspectors arrived in the control room after the plant

, trip and observed the plant shutdown. The inspectors ascertained the i status of the reactor and safety systems by observation of control room indicators and di'.ussions with licensee personnel concerning plant parameters, emergency system status and reactor coolant chemistry. A

! normal plant shutdown to flode 3 (Hot Shutdown) occurred and all systems responded as expecte This was the fourth inadvertant plant trip that has occured due to the RCPP!1's. As discussed in NRC Inspection Report 50-302/82-02, Paragraph 9b, the licensee modified the RCPPfl system hy adding time delays in the belief that these relays would reduce the susceptability of RCPPit's i grid perturbations. The design modification has apparently been ineffective as evidenced hy this plant trip and the licensee subse-quently requested'and received Technical Specification (TS) relief to

,

operate the plant at reduced power levels with the RCPPil's bypassed (or

'

inoperable) . Unresolved Item (302/82-02-11) was generated due to the inspector's finding that the time delay relay modification (t1AR 82-1-16) appeared to exceed TS system time delay limits. During a followup inspection on this Unresolved Item in paragraph 3 of NRC Inspection Report 50-302/82-05, it was noted hy the inspector that the time delay specified in i1AR 82-1-16 was in excess of the TS limit and

-

that the licensee will be taking additional actions to resolve the problems with the RCPPM's. These actions remain to be completed.

!

l-

.. .

.

The RCPPt1 modification (f1AR 82-1-16) was completed on flarch 3,1982, while the plant was in mode 3 (Hot Standby). The 11AR package contains a "itodification Safety Evaluation" that was prepared on 11 arch 2 and approved on flarch 3. This safety evaluation is conducted to meet the requirements of 10 CFR Part 50.59 to verify that the modification did not involve a change in the TS or an unreviewed safety question. The safety evaluation concluded that a TS change was not required nor that an unreviewed safety question existed. The inspector's review of this modification revealed that the new system time response exceeded the TS limits and that prior NRC approval had not been obtained prior to performing the modification. The RCPPft's are required for flode 1 (Power Operation) and 11 ode 2 (Startup). The plant remained in Mode 3 until the NRC permitted operation at a reduced power level while the time response issue was reviewed ', (paragraph 5).

Failure to obtain prior NRC approval for a plant modification that changes the TS is contrary to the requirements of 10 CFR Part 50.59 and is a violatio Violation (302/82-09-04): Failure to obtain prior NRC approval for a plant modification that changes TS requirement On liarch 27 at 746 p.m. , the plant experienced a reactor coolant pump (RCP) runback from 94% to 73% full power. The cause of this event was a shorted surge capacitor on the "B" phase of "C" RCP, causing the RCP to trip. Plant response to the runback was norma Reactor Protective System setpoints were reduced as required by TS to allow continued operation with 3 of 4 RCP in operation. The surge capacitor was replaced on April 2 and 4 RCP operation was reestablished. The inspec-tor reviewed this event and the licensee's actions and has no further questions at this tim . Emergency Drill

'

On flarch 30 an emergency drill was conducted by the licensee to verify the effectiveness of the new Radiological Emergency Response Plan and the Emergency Plan Implementing Procedure In addition to the licensee the participants in the drill included the State of Florida, Citrus and Levy Counties and the NRC. The drill was observed by a number of personnel that included the NR Details of this drill, including the results of the critiques held on llarch 31, are discussed in NRC Inspection Report 50-302-

/82-0 The inspectors have no questions in this area at this time.

9. Pipe hangers seismic restraints - Several pipe hangers and seismic l restraints (snubbers) on safety-related systems were observed to insure that fluid levels were adequate and no leakage was evident, j that restraint settings were appropriate, and that anchoring

points were not binding.

l j No discrepancies were 90ted in this area.
