- W. L. Stewart, Station Manager
- R. F. Saunders, Superintendent Maintenance
- J. L. Wilson, Superintendent Operations J. J. Peebles, Superintendent Technical Services

- D. J. Burke
- Attended exit interview Exit Interview The inspection scope and findings were summarized on October 19, 1979 with those persons indicated in paragraph 1 abov The licensee reconfirmed that a valve line up check was to be completed on safety class systems prior to startup of Unit 1 and acknowledged without comment that the inspector considered valve check lists to be inadequat.
Licensee Action on Previous Inspection Findings Not inspecte.
Unresolved Items Unresolved items were not identified during this inspectio.
Verification of Valve Positions and Positioning Requirements The inspector, accompanied by a qualified, experienced plant operator, verified valve positions and requirements for the several systems listed belo Current facility valve checkoff (positioning) sheets provided by the licensee to the Resident Inspector and current system drawings from the control room area and Superintendent of Technical Services' office were used for referenc Valves tagged to a position contrary to the positions shown on the valve checkoff sheet were not considered to be out of positio Marked up copies of the valve checkoff sheets utilized were left with the licensee and with the Resident Inspector who will complete any unfinished verification '
-2-Systems included in this verification were:
and Cooling Water and Cooling Water and Cooling Water
- 3 Diesel Air, Lube Oil, Post Accident Blowers Auxiliary Feedwater Residual Heat Removal Emergency Diesel Fuel readily accessible.)
(Containment Portion)
Oil System (Except Valves EEOl-09 which were not Outside Recirculation Spray System (containment portion)
Safety Injection System (containment portion)
Traveling Water Screens and Wash Pumps Containment Spray (except six valves:
1-CS-62, 63, 65, 66, 67, and 68).
Refueling Water Chemical Addition Tank During this valve position verification, several conditions that need licensee attention were observe Examples of missing valve labels were numerous, i.e., the valve has been assigned a number, is listed on a checkoff sheet, but the label tag was missin Specific examples were noted on the valve checkoff sheets provided to the license It was noted that the licensee had commenced a program to resolve this problem prior to this inspectio The old labels were a round brass
- disc with stamped letters and were affixed to low-temperature valves with a plastic tie or to high-temperature valves with wire.. They were hard to read and the plastic tie had a short lifetim The new labels are a stainless "dog tag" with embossed lettering and a stainless wire ti They appear to be far superior to the previous label tag Examples of inadequate valve checkoff sheets were note This includes failure to assign valve numbers, but does not include missing label plate These items are considered to be examples of noncompliance with Technical Specifications (280/79-60-01).
(1) Diesel Air Lube Oil and Cooling Water Systems:
(a)
Root cutouts to pressure gages on air flasks were not numbered nor listed on the checkoff shee (b)
Root cutouts to gages on diesel engine (except 1 gage) were not numbered nor listed on the checkoff shee (c)
Isolation and vent/drain valve to the pressure switches which control the air compressors were not numbered nor listed on the checkoff shee This line comes off the air manifol ' *

Safety Injection System:
Regulator PCV-SI-101, N2 Regulator te Pressurizer Relief Tank has been removed for a "long time"., yet is listed on the valve

checkoff shee (3) Emergency Diesel Fuel Oil System:
Several solenoid valves are listed to be checked "closed".
The licensee could not demonstrate any way to make such a check on a sealed solenoid valv (4) Auxiliary Feedwater:
(a)
Valves 1-FW-244, 245, and 246; suction drain valves to l-FW-P-2, 1-FW-P-3A, 1-FW-P-3B respectively; do not appear to exis The closest approximation is a capped drain that is part of the pump body in the suction are (b)
1-FW-P-4A and 4B have discharge gage snubber valves that have no numbe One can only guess if these are the valves mentioned on page 9 of OP31.2 checkoff sheet (no number is given on the checkoff sheet).
(c) Auxiliary Feed Pump A has a recirculation line with eductor (suction line terminates a few inches from floor) that is neither shown on the drawing nor all valves listed on the valve checkoff shee Other pumps do not have such a lin (5) Residual Heal Removal System valves 1-RH 36, 37 and 41 are listed as "normally open".
These are gland leakoff valves from pumps lA and lB and the leakoff suction header isolation valve respectively*.
These valves were shu Subsequent investigation determined that the pump gland system had been replaced by mechanical seals, the valves should be shut, and that the valve checkoff sheets had never been changed to reflect the modified system configuratio Several examples of valves out of position or broken equipment were noted by the inspecto A preoperation valve lineup check was being performed by the license The licensee was initiating action to correct these problems, as well as others found by the licensee staf (1) Auxiliary Feedwater (a)
Valve 1-FW-119, a tell-tale drain, was shut (but not tagged)
contrary to the valve checkoff sheet. It was shut because the root valve leaks throug (b)
Valve l-FW-166, a gage root cutout valve for B Auxiliary Feed Pump discharge pressure gage, was shut (but not tagged)
contrary to the valve checkoff shee When the valve was opened, the gage flooded with wate ""

Valve 1-FW-150, Firemain Supply to Auxiliary Feed Pump Lube Oil Cooler was closed contrary to the valve checkoff shee (2)
Outside Recirculation Spray System (inside containment) drain valves 1-RS-1005 and 1-RS-1007 were closed contrary to the valve checkoff shee (3)
Safety Injection System Accumulator discharge motor-operated valves MOV-1865 A and B had missing local position indicator parts. All of the local position indicator for MOV-1865-A was missing, the plastic tubular cover, which has the "open" and "shut" marks, for MOV 1865B was missin These valves do have remote indication.
