Exit Interview The inspection scope and findings were summarized on September 21, 1979, with those persons indicated in Paragraph I above. With respect to the item of noncompliance (302/79-39-01) discussed in paragraph 5 the Plant Manager acknowledged the item and committed to complete certain short term corrective actions by September 28, 1979.
These actions are:
Change the power ascension procedure by inserting hold points for heat a.
balance calculations during power ascension.
b.
Change the procedure for NI calibration to require verification of redundant signals for computer inputs.
c.
Instruct all operations personnel to follow the more/most restrictive action statement that is applicable for given conditions.
Additionally the licensee will make comparisons between the " hand" calculated heat balance and the offline and online computer calculated heat balances in an attempt to discover the cause of apparent discrepancies on September 17, 1979. This comparison is to be done and the NRC informed of the results by November 1, 1979.
With respect to the item discussed in Paragraph 6b the licensee committed to review all Maintenance (MP) and Preventative Maintenance (PM) procedures to identify those which need to be upgraded technically or to the format of 1390 123

-2-Administrative Instruction (AI) 400 by November 15, 1979 and to upgrade those applicable procedures by January 1, 1980. The licensee also committed to insure that planning coordinators are sufficiently familiar with applic-able procedures to be able to identify the disciplines required to do the work, by November 15, 1979.

Licensee Action on Previous Inspection Findings Not inspected.
4.
Unresolved Items Unresolved items were not identified during this inspection.
5.
Station Operations The inspectors monitored station operations in the control room at various times during the inspection.
During this period ae licensee notified inspectors of conditions contrary to technical specifications.
On September 17, 1979, during power ascension, operators noted that mega-watts electric output (MWe) did not agree with Nuclear Instrumentation (NI)
readings, MWe was higher than it should be for the NI-indicated power level. Several heat balance calculations were run using both online and offline computers in both automatic and semi-automatic (or " hand") modes, as a result it was determined that a feedwater (secondary) flow transmitter was out of calibration.
Power was reduced to 90% as indicated by MWe instrumentation and a heat balance was run on the offline computer in the " hand" mode in an attempt to verify the power level. The " hand" calculation indicated 90%; at this time NI power indication was 86%. During this entire period, operations were restricted to less than 92% THERMAL POWER by Technical Specification (T/S)
3.1.2.8 due to Xenon reactivity conditions in the core.
Later that day, when the work on the feedwater flow transmitter was completed a heat balance was run using the online computer.
This new heat balance showed that NI indication was out of calibration in the nonconservative direction and that power level was greater than 92%, approximately 96%.
The above referenced conditions are contrary to T/S 3.3.1.1, 3.0.3, and 3.1.3.8.
Since the existing conditions were in excess of those addressed in T/S 3.3.1.1, T/S 3.0.3 applies. T/S 3.0.3 requires "... the facility shall be placed in at least HOT STANDBY within one hour... unless correc-tive measures are completed that permit operation under permissible ACTION statements...." T/S 3.3.1.1 discusses NI operability requirements. T/S 3.1.3.8 requires TIERMAL POWER to be reduced below 92% within 15 minutes when Xenon is not within limits and power is above 92%.

-3-Based partially upon the fact that the power level had apparently been greater than 92% for approximately 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> already during feedwater flow transmitter maintenance the licensee decided to act in accordance with T/S 3.3.1.1 and disregard T/S 3.1.3.8; therefore, first the NI's were calibrated (1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> requirement) then power was reduced approximately 64 minutes after discovery (15 minute requirement).
This action of neglecting to act in accordance with the more restrictive action statement is considered an item of noncompliance with T/S 3.1.3.8 (302/79-39-01).

Maintenance a.
Review conducted The inspectors conducted a review of maintenance procedures as follows:
MP 105, Filter Removal and Replacement (Liquid)
MP 122, Disassembly and Reassembly of Flanged Connections MP 121, Pump Repacking MP 134, Disassembly and Reassembly of Can-Type Waste Disposal Pumps PM 112, Inspection / Cleaning and Shooting of Heat Exchanger Water Boxes and Tuoe Sheets DRWG #FD-302-671, Chemical Addition The inspectors reviewed 83 safety-related work requests (WR) dated from April 1978 thru June 1979 and located in station records.
The inspectors also monitored the performance of portions of the following work conducted on September 18 and 20, 1979.
WR 1003, Replace gasket in CAP-1B WR 1017, Shoot and clean Decay Heat Closed Cycle Heat Exchanger "B" A post maintenance valve lineup per SP-349 " Emergency Feedwater System Operability Demonstration" The inspector also reviewed the training and qualification records of five maintenance mechanics, technicians and and foremen.
The above documentation was reviewed to verify:
-
Administrative approval was obtained prior to initiating work Where required, maintenance was performed using an approved
-
procedure 1390 125

.
-
Where required, functional testing was performed prior to return to service
-
Quality Assurance review was performed
-
Maintenance was performed by qualified personnel
-
Where required, ; eportable occurrence report was submitted in connection with the maintenance.
The inspector used one or more of the following acceptance criteria for inspecting the above items:
-
ANSI N18.7 (1976)
-
ANSI N45.2.9 (1971)
-
Technical Specifications

P0QAM b.
Procedures hot Formated Correctly The inspector found the Enclosure 3 (data sheet) of MP 105, Filter Removal and Replacement (Liquid), lacks adequate provisions to record certain requirements such as torque wrench numbers and sign-offs for step 6.2 (prerequisites). As a result, the maintenance work done on 3/12/79 under the Work Request No. 7221 failed to record the torque wrench number while the work performed one day later under the Work Request 7243 recorded the torque wrench number. The inspector noted that this was due to an error made while preparing the last revision to this procedure.
The inspector also found on 9/20/79 that while witnessing the gasket replacement activities on the boron transfer pump (CAP-1B) that the Electrical Work Request (No. 10430) failed to require the appropriate procedure (MP 134) for the electrical reassembly and test work.
The procedure was referenced for the mechanical crew under the mechanical work request (No. 1003), but that step 8.6 of MP 134 was not done because this is applicable only for the electricians. This discrepancy was created because a mechanical planner initiated the electrical work request without realizing that the procedure MP 134 also contains the elec-trical steps. The inspector notified the planner of this problem prior to the electrical work and requested that the procedure be used.
This work was accomplished using the required procedures.
