3. Licensee Event Report (LER) Followup (Units 1 and 2)

Through direct observation, discussions with licensee personnel, and review of records, the following event reports were reviewed to determine that reportability requirements were fulfilled, immediate corrective action was accomplished, and corrective action to prevent recurrence has been accomplished in accordance with Technical Specification Unit 1 85-003-00 Reactor trip due to high reactor coolant system pressure Unit 2 84-013-00 Reactor trip due to dropped control element assembly (CEA)

84-019-00 Reactor trip due to inverter switching by operator 84-024-00 Reactor trip due to dropped CEA 84-026-00 Reactor trip due to dropped CEA 85-004-00 Reactor trip due to loss of main generator excitation For each of the LERs listed above, the licensee has taken preventive and corrective action. This action includes repair or replacement of system components, revision of procedures for greater clarity, or increased individualized training, as appropriat The actions taken by the licensee should decrease the number of reactor trips in the areas listed abov No violations or deviations were identifie . Followup on IE Information Notice 83-75 (Units 1 and 2)

IE Information Notice 83-75, " Improper Control Rod Manipulation," was issued on November 3, 1983. The NRC inspector reviewed the licensee's actions to this issue in more detail in response to a request from the NRC Office of Inspection and Enforcemen The NRC inspector verified the following:

. Licensee procedures define the steps necessary for recovery from a mispositioned control ro . Procedures are implemented for verifying rod position when one form of normal indication is los . Training has been provided for operators in the above area No violations or deviations were identifie _ _ _ .

5. Operational Safety Verification (Units 1 and 2)

The NRC inspectors observed control room operations, reviewed applicable logs, and conducted discussions with control room operator The inspectors verified the operability of selected emergency systems, reviewed tagout records, verified proper return to service of affected components, and ensured that maintenance requests had been initiated for equipment in need of maintenance. The inspectors, by observation and direct interview, verified that the physical security plan was being implemented in accordance with the station security pla The inspectors verified implementation of radiation protection controls during plant activitie The NRC inspectors toured accessible areas of the units to observe plant equipment conditions, including potential fire hazards, fluid leaks, and excessive vibratio The inspectors also observed plant housekeeping and cleanliness conditions during the tour. No housekeeping problems were noted during the tours by the inspector The NRC inspector walked down the accessible portions of the Unit 1 penetration room ventilation syste The walkdown was performed using Procedure 1104.43 and Drawing M-264. During the walkdown, no discrepancies were noted by the NRC inspector between the procedure, drawing, and plant as-built condition The NRC inspectors also walked down portions of the Unit 2 containment spray syste This walkdown was a continuation of the walkdown initiated during the previous month's inspectio During the walkdown, the NRC inspectors noted that a valve was not positioned as required by the Category E valve lineup sheet in Procedure 2102.01, " Plant Pre-heatup and Pre-critical Checklist." Category E valves are valves that are normally locked open or shut and are in a required position to ensure safety systems will fulfill their intended functio If a valve is in a position other than the position stated in the Category E lineup, the valve is required to be listed on an exception sheet (Form 1015.01C) which is maintained in the control roo The valve found mispositioned by the NRC inspectors was 28S-32. This is the suction valve for the sodium hydroxide tank recirculation pum Even though the valve was mispositioned, it did not cause any safety-related component or system to be inoperable. The NRC inspectors checked Form 1015.01C to verify that 285-32 had been entered. There was no entry for this valve. The Unit 2 operator immediately entered 285-32 on the valve exception lis Subsequent review revealed that the Unit 2 operators had failed to transfer the valve number from the valve lineup list to the exception list. This is an apparent violatio (368/8517-01)

On June 18, 1985, the Unit 2 core operating limit supervisory system (COLSS) was declared inoperable due to licensee identified problems. The COLSS provides direct on-line reactor core status monitoring information to the plant operator. The information provided includes the departure from nucleate boiling ratio (DNBR) limit, licensed core average power limit, peak linear heat rate limit, azimuthal flux tilt limits, and axial shape index upper and lower limit While reviewing COLSS output data, a licensee representative noted that the DNBR limit was listed as 145 percent power. Due to this relatively large value, a review was performed to determine the cause of the erro The licensee found that an error had been made in the format used for the computer input data. Even though the input was checked by two different individuals, the error was not detected. The licensee also found that the output data had been reviewed but the output error went undetecte The licensee performed separate calculations to determine the correct DNBR limit valu The results indicated that the value should have been approximately 105 percent power. At no time during the period since the data was input did reactor power exceed 105 percent. The licensee corrected the input error, reverified the code, and declared the COLSS operable. The licensee plans to submit a 30-day written report to the NR These reviews and observations were conducted to verify that facility operations were in conformance with the requirements established under Technical Specifications, 10 CFR, and administrative procedure . Monthly Surveillance Observation (Units 1 and 2)

The NRC inspector observed the Technical Specification required surveillance testing on the Unit 2 emergency diesel generator (Procedure 2104.36) and verified that testing was performed in accordance with adequate procedures, test instrumentation was calibrated, limiting conditions for operation were met, removal and restoration of the affected components were accomplished, test results conformed with Tecnnical Specifications and procedure requirements, test results were reviewed by personnel other than the individual directing the test, and any deficiencies identified during the testing were properly reviewed and resolved by appropriate management personne No violations or deviations were identifie . Monthly Maintenance Observation (Units 1 and 2)

Station maintenance activities of safety-related systems and components listed below were observed to verify that they were conducted in

-.

.

accordance with approved procedures, Regulatory Guides, and industry codes or standards; and in conformance with Technical Specification The following items were considered during this review: the limiting conditions for operation were met while components or systems were removed from service; approvals were obtained prior to initiating the work; activities were accomplished using approved procedures and were inspected as applicable; functional testing and/or calibrations were performed prior to returning components or systems to service; quality control records were maintained; activities were accomplished by qualified personnel; parts and materials used were properly certified; and radiological and fire prevention controls were implemente Job orders (J0) were reviewed to determine status of outstanding jobs and to ensure that priority is assigned to safety-related equipment maintenance which may affect system performanc The following maintenance activities were observed:

. Replacement of a fan in the Unit 2 inverter 2Y13 (JO 87443)

. Repair of the feel oil vault fire detectors power supply (JO 88819)

. Adjustment of level switches for Unit 2 emergency diesel generator fuel oil day tank (JO 83174)

No violations or deviations were identifie . Startup Testing After Refueling (Unit 2)

The NRC inspector reviewed the data from the following completed core physics tests associated with the startup after the fourth refueling of Unit 2, and verified that the results met the acceptance criteria and that all deficiencies were resolve Procedure Title 2103.16 Heat Balance Calculation 2302.01 Incore Detector Channel Check 2302.06' RTD Response Time Testing 2302.09 Moderator Temperature Coefficient at Power 2302.16 RCS Calorimetric Flowrate Calibration 2302.21 Sequence fcr Low Power Physics Testing Following Refueling 2302.23 Low Power Physics Base Power Level Determination 2302.24 CEA Symmetry Check 2302.38 Linear Power Subchannel Calibration No violations or deviations were identifie *

9 Procedures Review (Units 1 and 2)

.This inspection was conducted to verify that the licensee's overall plant procedures are in accordance with regulatory requirements, temporary procedures and procedure changes are made in accordance with Technical Specification requirements, and the technical adequacy of the reviewed procedures is consistent with desired actions and modes of operatio The NRC inspector reviewed the following procedures:

Number Title Unit 1 1000.04 Procedural Program Requirements 1000.05 Procedure Format and Content 1000.06 Procedure Review, Approval, and Revision Control 1102.04 Power Operation 1102.06 Reactor Trip Recovery 1104.02 Makeup and Purification System Operating Proceduce 1104.04 Decay Heat Removal Operating Procedure 1106.16 Condensate Feedwater and Steam System Operations 1203.28 Loss of Decay Heat Removal System Unit 2 2102.04 Power Operation 2102.06 Reactor Trip Recovery 2104.02 Chemical and Volume Control System Operation 2104.04 Shutdown Cooling System 2106.16 Condensate Feedwater and Steam System Operations 2202.32 Loss of Shutdown Cooling 2202.24 Steam Supply System Rupture In this review, the NRC inspector verified that review and approval of procedures is performed in accordance with issued administrative procedures and Technical Specifications, the method of incorporating temporary procedure changes into procedures for emergencies and other significant events does not preclude proper and timely operator action during abnormal plant conditions, and overall procedure content is consistent with Technical Specifications and adequate to control safety-related operations within applicable regulatory requirements. The NRC inspector also verified that the procedures reviewed, including checklists and related forms, in selected plant areas are current with respect to revisions and temporary change The NRC inspector also verified that procedure changes had been made to reflect Technical Specification or license revisions, except in one case recently identified by the licensee. This case involved the timely issue

of a procedure implementing the monthly surveillance tests of the recently installed containment high-range radiation monitors invoked by Amendment 94 to the Unit 1 Technical Specifications. This amendment was issued January 31, 1985, but due to an administrative error, the procedure was not issued until June 12, 198 Upon identification of the error, the radiation monitors were declared inoperable by the license The licensee issued Procedure 1304.143, "High Range' Containment Radiation Monitor Test," and the surveillance was performe The surveillance

~

results indicated that no problems existed with the monitors; therefore, the monitors were declared operabl The licensee could not establish a definite root cause for the oversigh The licensee plans to submit a 30-day written report to the NR No violations or deviations were note . Regulatory Effectiveness Review (Units 1 and 2)

The NRC inspector participated as a team member in the Regulatory

'

Effectiveness Review performed by the NRC Office of Nuclear Material Safety and Safeguards (NMSS). This review was conducted to evaluate the effectiveness of the ANO safeguards program and to determine if the security systems meet regulatory requirements. A detailed discussion of the results of the review will be provided in a report issued by NMS . Exit Interview
