Emergency Diesel Generator (EDG) 1-1 remains tagged but is operable. 1./
Maintenance on an air-start motor has been delayed pending receipt of part (3)
Continuous indications were noted for hi/lo annunciators on the quench tank and the SIRW tan The quench tank level indication is believed faulty due to suspected boiling in the instrument reference le The SIRW tank level was below the low level alarm but above the low level limit established in the technical specification The inspectors noted that with the continuous alarm indication, SIRW tank level information and control (to assure the presence of sufficient borated water) depends on frequent operator observation of level instrument No further automatic indications occurs until the level fails far below that specified in the technical specifications and assumed in accident analysi These items were discussed at the exit intervie Control Room Manning and Shift Turnover Event Reports and Deviation Reports Deviation reports78-236 and 237 concerning the operability of the auxiliary feedwater pumps on July 5, 1978, were reviewe The licensee's actions following failure of the motor-driven auxiliary feedwater pump (P8A) were examine The inspectors questioned the timeliness of followup testing of the fire pump and of the steam-driven auxiliary feedwater pump (PSB) required by technical specification This matter was discussed at the management exi The reportability of Deviation report 78-252, concerning receipt of several incore detector alarms while at 88%
power on July 18, 1978, was reviewe This matter was discussed at the exit interview, along with general reporting requirements as they relate to operations with certain components in a degraded conditio No items of noncompliance or deviations were identifie _/
IE Inspection Report No. 050-255/78-2 * Plant Tour The inspectors conducted a comprehensive facility tour to observe for general housekeeping, proper equipment tagging, component vibration or fluid leaks, and establishment of radiation controls and fire barrier Turbine building Electrical penetration room A spare installed electrical penetration housing was noted which appeared loosely supported by wooden shims rather than welded steel leg Service-water building Minor corrosion was noted on battery cables for one diesel-driven fire pum Turbine lube-oil room A water drain hose was found exiting the room through an ajar fire doo This was corrected during the inspectio Chemistry Department areas Assorted chemicals and what appeared to be general debris (including some cardboard and paper) were being stored adjacent to each othe Auxiliary building Two open and poorly-identified containers were noted which appeared to contain oi The inspectors and licensee personnel discussed the need for positive controls on lubricants or fuel intended for use in safety-related component Fuel handling area A general cleanup and improved accessibility within the area were note The potential for improved personnel contamination protection measures was discussed with the member of the radiation protection staff on duty, who had not noted torn anti-contamination clothing on one worke Items noted during the plant tour were discussed at the management exit intervie No items of noncompliance or deviations were identified.

- Plant Design Changes/Modifications Selected plant modifications performed in 1977 were reviewed by the inspector The review covered proper licensee review and approval, adherence to 10 CFR 50.59, use of procedures including hold points and acceptance tests, and updating of procedures and as-built drawings as appropriat Changes to the boric acid heat tracing monitoring system to consolidate indications (Facility Change 320), and installation of current monitoring to the EDG oil transfer pumps (Facility Change 321), were examine Additional items will be examined during a future inspectio No items of noncompliance or deviations were note.
Outstanding Inspection Items The inspectors reviewed the following inspection items to determine the appropriate actions were completed by the license Flowpath from Fire Protection System to the Auxiliary Feedwater Pumps Section Header.1_/
The inspectors observed the opening of the valves individually on November 16, 1978, which provide suction for the auxiliary f eedwater pumps from the fire protection syste The lines from the fire protection system to the suction supply valves and the condensate system to the suction supply valves were flushed to verify the flowpath The manual supply valves to the auxiliary feedwater pump suction header are being included within the surveillance test program by the license No further questions are required of this matter at this time and this item is considered close The inspectors reviewed the licensee program for boric acid heat tracing maintenance and operations.]/ The review included:
(1)
Operation of the primary and secondary heat tracing circuit,/
IE Inspection Report 50-255/78-1 l/ IE Inspection Report 50-255/78-2 **
(2)
Use of the local power indicator lights on the primary and secondary heat tracing circuit (3)
Surveillance of the heat tracing circuits by routine current readings to assure circuit operabilit (4)
Maintenance of the heat tracing circuit (5)
Critical (TR-200) and noncritical (TR-201) heat tracing circuit recorder The review revealed that the licensee routinely operates with both the primary and secondary heat tracing circuits energized; the local power indicator lights are not routinely utilized to assure circuit operability; the surveillance of the heat tracing circuits by routine current readings has not been performed; and the heat tracing circuits could be maintained operable with dedicated maintenance activitie This matter will remain ope (These items were discussed at the management exit.)
No items of noncompliance or deviations were identifie.
Management Exit Interview The inspectors conducted a management exit interview (attended as noted in Paragraph 1) at the conclusion of the inspection on November 17, 197 The inspectors summarized inspection scope and finding The licensee made the comments or statements noted below in response to items identified by the inspector The licensee stated expeditious repairs were made to the inoperable boric acid pump (this was completed November 17)
and acknowledged the need to maintain both pumps operabl (Paragraph 2.f(l)) Operations with continuing level alarms on the quench tank and the SIRW tank were discusse The licensee noted the reference leg for quench tank level had been relocated once before, and that technical specifications are silent with respect to this paramete Concerning the SIRW tank level alarm, the licensee indicated level had intentionally been reduced somewhat to provide capacity for water transfer from a spent fuel tilt pi Shrink due to an ambient temperature drop then caused the annunciated conditio The licensee will review his administrative alarm set point as it affects operational flexibilit (Paragraph 2.f(3))
- Items noted during the plant tour were discussed, the licensee stating each would be reviewed for appropriate actio (Paragraph 3) The inspectors discussed specific concerns related to the maintenance and surveillance of the boric acid heat tracing system including the operations of the primary and secondary heat tracing circuits, the local power indicator lights, the current readings for the individual heat tracing circuits, the maintenance of the heat tracing circuits, and the use of the temperature recorders (TR-200 and TR-201).
The licensee stated that the general operating practices concerning the heat tracing syst~m would be reviewed, the current readings would be taken, and a routine established to assure continued circuit operabilit The inspectors stated that this matter would be further reviewed and evaluated during the next scheduled inspectio (Paragraph 5.b)
The licensee acknowledged the inspectors statements concerning the timeliness of followup testing after the auxiliary feed-water pumps failure on July 5, 1978, to assure the require-ments of the TS LCO' s are me (Paragraph 2. h)
The licensee acknowledged the inspectors statements concerning the general reporting requirements for systems or components operating in a degraded conditio The discussion specifically addressed incore alarms, snubbers, and fire barrier (Paragraph 2. h)
