(11) Surveillance Testing - Surveillance testing was observed and procedures reviewed to verify that:
-approved procedures were being used;
-qualified personnel were conducting the tests;
-testing was adequate to verify equipment operability;
-procedures were adequate to accomplish required results;
-calibrated equipment, as required, were utilized; and,
-Technical Specification requirements were being followed.
The following tests were observed and procedural reviews conducted:
-SP-310, Daily Surveillance of the Loose Parts ltonitoring System;
-SP-190, Control Complex Smoke Detector Testing (164' elevation only);
-SP-351, Nuclear Services Flow Path Operability (data review only);
-SP-110, Reactor Protective System tionthly Functional Test (Channel
"C");
-Q0P-21, Testing of Safety-Related Relays;
-SP-347, Emergency Core Cooling and Boration System Flowpath;
-SP-130, Engineered Safeguards lionthly Functional Test (section 6.2);
-SP-169, Plant Safety-Related Instrument Calibration (Procedure review);and,
-Relay Systems Quality Operating 11anual (procedure review).
These reviews and observations identified the following items; a.
The Relay Systems Quality Operating flanual piocedures contain blank, " Relay Data and Setting Sheets" upon which the relay setting calculation.results are recorded.
These relay setting calculations are performed by the Realy Staff Engineer in accordance with procedure QOP 1.0, Organization and Responsi-bilities.
i The inspector reviewed these procedures and discussed their implementation with licensee personnel. The inspector noted that
!
the completed " Relay Data and Setting Sheets" are not reviewed by
,
the Plant Review Committee (PRC) as are the entire Relay Systems i
Quality Manual procedures, but do, however, receive Nuclear Engineering Department approval prior to being issued to the
,
l field. Since these completed data sheets are used by relay technicians to provide the actual data to which the relays are calibrated, it appears that these sheets with the setting data should be an integral part of the procedure.
The licensee will review the implementation of these data sheets to determine if the completed sheets will be included as part of the PRC approved QOPs. This review will be completed and a method for controlling the data sheets implemented by January 1,198 r
.
.
.
.
Inspector Followup Item -(302/81-19-02):
Review the licensee's actions with respect to revising the relay department procedures to include completed Relay Data and Setting Sheets.
The ins 7ector also queried licensee representatives to determine if the procedures utilized manufacturer's technical manuals to accomplish the calibrations since the manuals were referred to as references in the procedures. The licensee reviewed the procedures and noted that one procedure Q0P 30, Loss of Excitation Relay Type CEH, referred to a drawing in a technical manual. The licensee will revise Q0P 30 to incorporcte this diagram as a part of the procedure by January 1, 1982.
Inspector Followup Item (302/18-19-03):
Verify relay test procedure Q0P 30 is revised to include technical manual drawing.
b.
Surveillance procedure SP-169, Plant Safety-Related Instrument Calibration, is used to calibrate the balance of plant instrumentation.
Data sheets for this procedure are not contained with the procedure.
The setpoints on these sheets are controlled by a ccmputed generated
"Setpoint Document" which is not a controlled document nor is it approved by the Plant Review Committee (PRC), however the document is reviewed by Nuclear Engineering and changes to the document are made in accordance with the licensee's modification system.
i This finding was identified by the licensee and procedure SP-169 will be revised by October 15, 1981 to include the data sheets.
In addition, the licensee will review other procedures to insure that other safety-related equipment procedures do not refer to the Setpoint Document.
Unresolved Item (302/81-19-04):
Revise SP-169 and review other procedures to insure that the Setpoint Document is not used to orovide setpoints.
c.
While reviewing SP-110, Reactor Protective System Functional Testing, the Reactor Building (RB) Pressure Channel electrical schematic, the inspector determined that the method used to functional test the high RB pressure trip channels did not include the injection of a simulated pressure signal into the RB pressure switches. The method used would only verify operability of the circuitry downstream of the RB pressure switches. A review of Technical Specification (TS) 4.3.1.1.1, Table 4.3-1 and TS definition for funcontional testing indicated the present method for functionally testing the high RB pressure trip channel was in accordance with the testing requirements for an analog channel. The inspector's review of the RB pressure channel indicated that the channel should be classified as a bistable channel due to the fact that the channel only sees two states (pressure switch contact closed indicates RB pressure less than 4 psig, contact open indicates pressure greater then 4 psig). The TS requirements for bistable channel functioral testing would require the injection of a simulated
.
.
.
.
^
pressure signal into the RB pressure switch to verify operability of the pressure switch and the rest of the channel. The inspector discussed this issue with the licensee and the inspector's comments were acknowledged. The licensee called a meeting of the Plant Review Committee (PRC) to review the issue. As a result of this meeting, the licensee detennined that the high RB pressure trip channel was an analog channel. The inspectors referred this issue to NRC Region II for resolution. On August 27, 1981, the licensee was informed by NRC that the high RB pressure trip channel was considered to be a bistable channel and should be tested in.ccordance with TS requirements.
The licensee then initiated a procedure change to SP-110 to include functional testing of the RB pressure switches.
Functional testing was completed at 1758 hours0.0203 days <br />0.488 hours <br />0.00291 weeks <br />6.68919e-4 months <br /> on August 27, 1981.
Failure to perform adequate monthly functional testing of the high RB pressure trip channel as required by TS 4.3.1.1.1 Table 4.3-1 is considered to be a violation.
Violation (302/81-19-05):
Failure to perform adequate monthly functional testing of the high RB pressure trip channel as required by TS 4.3.1.1.1, Tabl e 4.3-1.
(12) Haintenance Activities - The inspector observed maintenance activities to verify that:
-Correct equipment clearances were in effect;
-Work Requests (W/R'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 followed.
The following maintenance activities were observed:
-Decay heat closed cycle cooling pump (DCP-1A) coupling lubrication in accordance with PM-133, Equipment Lubrication Procedure;
-DCP-1A pump to coupling alignment in accordance with MP-114, Disassembly and Reassembly of DCP-1A and DCP-1B;
