Licensee Action on Previous Inspection Findings (Closed) Deficiency (79-23-02) - Failure to attend required Operator Retraining Program Lectures - Paragraph 6.c of RII Report 50-302/79-23. Two licensed operators had failed to attend required retraining lectures af ter having scored less than eighty percent in an area of their annual requalification examinations.
She inspector verified that affected personnel had been retrained and reexamined in deficient areas with satisfactory results.
(Closed) Deficiency (79-23-04) Inadequate 10 CFR 19 Training - Paragraph 5.b of RII Report 50-302/79-23.
General employee training lesson plan l
lacked the requisite 10 CFR 19.12 instruction. The inspector verified that Administrative Instruction AI-800, Revision 7, has been revised to require
this training be conducted. This has been implemented.
(Closed) Deficiency (79-24-03)
Inadequate Plant Equipment Clearance
-
Titles - Paragraph 5.F of RII Report 50-302/79-24. Several active clearance
,
titles were inadequate as entered in the clearance log. The inspector j
verified that personnel were entering more descriptive title information in
{
the clearance log.

(Closed) Deficiency (79-29-02) - Improper Control Rod Drop Time Heasure-ments - Paragraph 5 of II Report 29.
Drop time interval was measured to the'beginning, rather than the midpoint, of the 25% limit switch voltage pulse.
The inspector verified that step 6.9 of Surveillance Procedure SP-102 has been revised to require proper measurement.
4.
Unresolved Items.
Unresolved items are matters about which more information is required to determine whether they are accentable or may involve noncompliance or deviations.
New unresolved i'
identified during this inspection are
,
discussed in paragraphs 6 ano..
5.
Plant Operations Plant Operations were reviewed by the inspector to ascertain conformance with regulatory requirements and technical specifications.
a.
Daily Activities The inspector maintained daily awareness of plant status and significant activities through discussions with members of the plant staff and operating personnel. Selected portions of the various daily log books and control room data sheets were examined on a daily basis during the report period.
The inspector made several plant tours in selected areas of the turbine and auxiliary buildings. The control room was
,
visited on a more frequent basis than other portions of the plant.
Observations included instrument readings and recordings, housekeeping and status of operating systems and components. Informal discussions were held with operators and other personnel on work activities and status of equipment. Questions developed by the inspector were satis-factorily answered.
Interviews with a number of plant operations personnel were held on the day and night shifts. Supervisors and control operators actions were observed. Their actions and activities were responsive to the activities in progress.
Operators were responsive to annunciator alarms and appeared to be cognizant of plant status, b.
Plant Jumper Log The inspector reviewed the Plant Jumper Log Book to verify that jumpers placed on equipment were controlled and that a safety evaluation had
,
been performed on each jumper.
There is still a relatively large
_,
number of active jumpers being maintained in the log, and the licensee is continuing to purge this log of unnecessary jumpers. No discrepancies were noted at this time.

-3-Plant Equipment Clearance and Switching Orders c.
The inspector reviewed the Plant Equipment Clearance and Switching Order logs to verify that equipment or components, required for the plant mode of operation at the present time (Mode 1), were available for operation as required by Technical Specifications and that the clearance logs were properly filled out and completed as per CP-115,
"In-Plant Equipment Clearance and Switching Orders". Section 6.1.9 of CP-115 requires independent verification of proper system valve positions during restoration following maintenance. The inspector verified that clearance order number 10-48 was released on October 22, 1979, without having had the independent verification performed. This clearance was associated with the Nuclear Closed Cycle Cooling System. The licensee immediately performed the independent verification when notified by the inspector. All valves were found to be properly positioned. This is an Infraction (79-46-01).
t d.
Plant Tours As part of the plant operations review, the inspector toured accessible portions of the plant. During the tour, observations were made regarding the general plant housekeeping and cleanliness and radiation control practices. In general, these areas were found to be satisfactory.
6.
Floor Drain Radioactive Airborne Release Problem The inspector reviewed the circumstances of a recent in plant airborne release in the auxiliary building which originated from the primary system sample sink drain.
Internal airborne releases from the drain system have been a recurring problem at this facility. This most recent event occurred when technicians were attempting to transfer water from an auxiliary building collection sump to the floor drain system via a portable pump. The floor drain system was inadvertantly pressurized sufficiently to blow the loop seal on the primary sample sink drain and allow radioactive gases to escape to the sink exhaust hood. The release consisted of noble gases and did not exceed any - release limits.
The gases were scavenged by the auxiliary building exhaust ventilation system, filtered, and released from the plant through the vent stack. The auxiliary building was evacuated during this event and no personnel were overexposed.
The licensee has had Gilbert Engineering survey the entire Radioactive Waste Disposal System, including the floor drain system, to upgrade this capability. However, their final recommendations have not been received by
,
the licensee to date. The licensee stated that final resolution of this problem will be based on the Gilbert report. This is designated as Unresolved Item 79-46-0,-

Review of IE Bulletins The inspector reviewed applicable IE Bulletins with licensee personnel to ascertain; that they have been received by the licensee and reviewed for applicability by cognizant supervisory personnel; that information discussed in the licensee's reply was accurate; and that corrective action taken was effected as described in the reply. The following IE Bulletins were reviewed:
Bulletin 79 15, Deep Draft Pump Deficiencies The inspector reviewed the surveillance and maintenance history of the four deep-draft pumps identified in the licensee's response to this bulletin.
Although no problems of the nature described in the bulletin were identified from the naintenance history, the inspector did identify a recurring inter-mittent vibration problem with the two Nuclear Services Cooling Seawater Pumps RW22A and 2B.
The licensee stated that this problem was due to foreign debris (wood) being trapped in the pump suctions. Divers were dispatched in June to inspect the intake structure and pump suction bell housings and the wood was recovered.
It was not known how the wood got t
into the bell housings.
Pump vibration readings returned to acceptable levels following removal of the wood; however, high vibrations readings were again observed in August.
The inspector brought this problem to the attention of the licensee and they committed to having divers make another inspection during November.
The inspector toured the intake structure area and identified the following two discrepancies with the travelling screen system:
It is possible to run the travelling screens without having the screen a.
.
wash system in operation.
,
b.
Approximately half of the screen wash nozzles were plugged rendering them inoperable.
Both of these discrepancies could contribute to carryover of foreign debris.
The licensee committed to correcting these problems.
This bulletin will remain open pending final resolution and the problem is further designated as Unresolved Item 79-46-03.
8.
Review of IE Circulars The inspector reviewed applicable IE Circulars with licensee personnel to as-certain that they have been received on site and reviewed by cognizant super-
,
visory personnel. Licensee's actions on the following IE Circulars were reviewed:
Circular Numbe.r 77-CI-15, Fuel Oil Degradation The inspector verified the liccensee's action to be adequate and has no further questions at this tir..:. This circular is closed.
Circular Number 78-CI-15, Tilting Disc Check Valves This circular remains open pending c mpletion of the licensee's inspection of the physical orientation or one valves as installed.
