Jnspection Summary Inspection from February 2. 1993. throuah March 1. 1993 (Report Nos. 50-454/93003(DRP):50-455/93003(DRP)).
Areas Inspected: Routine, unannounced safety inspection by the resident inspectors of operation:1 safety verification, current material condition,
'
housekeeping and plant cleanliness, radiological controls, security, maintenance activities, surveillance activities, outage, and refueling activities.
Results: Of the nine areas inspected, no violations, unresolved items or followup items were identified.
The following is a summary of the licensee's performance during this inspection period:
i Plant Doerations The licensee's performance in plant operations was good for this inspection period. The shift briefing continues to provide a good rundown of work
.
planned for shift. This ~is especially helpful during the refueling outage.
The " dark board" continues to be the standard of plant operations. The outage
has progressed smoothly and on schedule. Shutdown risk assessment was effectively integrated into the outage. The results of these assessments, as they affected day to day opera'. ions, were effectively communicated to plant'
personnel.

Plant Operations Unit 1 operated continuously for 372 days before being shutdown for. the fifth refueling outage on February 5,1993.
,
Unit 2 operated at power levels up to 100% in the load following mode ~
j during this inspection period.
a.
Operational Safety Verification (71707)
The inspectors verified that the facility was being operated in
conformance with the licenses and regulatory requirements, and that the management control system was effectively carrying out.
its responsibilities for safe operation.
(
On a sampling basis the inspectors verified proper control. room staffing and coordination of plant activities; verified operator
.,
adherence with procedures and technical specifications; monitored control room indications for abnormalities; verified that
-
'
electrical power was available; and observed the frequency.nf-plant and control room visits by station management.

Unit 1 Outaae
-
-I l
The outage planning and scheduling,. maintenance and refueling performance was considered to be good. The outage has progressed smoothly and on schedule. The shutdown risk assessment was-
,
integrated effectively into planning'and scheduling-the outage.
The results of the assessment as it affects day to day operations was efficiently communicated to the plant personnel.
No
_
occurrence was noted where a scheduled job was started and had to
.
be stopped because of inappropriate scheduling and plant conditions.
,
c.
Current Material Condition (71707)
,
The inspectors performed general plant as well as selected system and component walkdowns to assess the general and specific material condition of _the-plant, to verify-that nuclear work requests (NWRs) had been initiated for identified equipment problems, and to evaluate housekeeping. Walkdowns included an assessment of the buildings, components, and systems for proper.
identification and tagging, accessibility, fire and security door integrity, scaffolding, radiological controls, and any unusual conditions. Unusual conditions included but were not limited to water, oil, or other liquids on the floor or equipment; indications of leakage through ceiling, walls or floors; loose insulation; corrosion; excessive noise; unusual temperatures; and
_
abnormal ventilation and lighting.
d.
Housekeepina and Plant Cleanliness The inspectors monitored the status of housekeeping and plant cleanliness for fire protection and protection of safety-related equipment from intrusion of foreign matter.
,
Housekeeping remains excellent.
Painting continues in various areas of the plant. Painting increases the illumination level and improves the work area.
Plant Cleanliness continues to be good.
with the craft personnel maintaining clean work areas.
No fire hazards were noted.
e.
Radiolooical Controls (71707)
The inspectors verified that personnel were following health physics procedures for dosimetry, protective clothing, frisking,
,
posting, etc. and randomly examined radiation protection instrumentation for use, operability, and calibration.
f.
Security Each week during routine activities or tours, the inspectors monitored the licensee's security program to ensure that observed actions were being ' implemented according to the approved security

plan. 'The inspectors noted that persons within'the protected area
1 displayed proper photo-identification badges and those individuals
,
requiring escorts were-properly escorted. The inspectors also verified that checked vital areas.were locked and alarmed.
Additionally, the inspectors also observed that personnel.and c
packages entering the protected area were searched by appropriate equipment or by hand.
No violations or deviations'were identified.

Maintenance / Surveillance (62703 & 61726)
a.
Maintenance Activities (62703)
Routinely, station maintenance activities were observed and/or reviewed to ascertain that they were conducted in accordance with approved procedures, regulatory guides.and industry codes or standards, and in conformance with technical specifications.
The following items were also considered during this review:
approvals were obtained prior to initiating the work; functional testing and/or calibrations were performed prior to returning components or systems to service; quality control records' were -
maintained; and activities were accomplished by qualified personnel, portions of the following maintenance activities were observed and -
reviewed:
- NWR's B97350 &
Unit 1 RHR Cubicle Cooler Ball Valve

Refuelina Activities (60710)
During the refueling outage, the inspectors observed the licensee's fuel
-
handling operations and discussed refueling operations with_ plant operators and fuel handling personnel. The licensee used approved
procedures for fuel accountability and movements._ Communications
between the control room and fuel handlers were established and effective. The inspectors witnessed fuel handling operations during several shifts from the control room, in the fuel building, and in containment.
During the Unit 1 outage, all of the fuel was unloaded from the reactor,_
moved to the spent fuel pool, ultrasonically tested for indications of fuel leaks, stored in the spent fuel pool, and then reloaded into'the l
reactor as required for the next fuel cycle. One fuel pin was found to
i be leaking and the fuel assembly was " reconstituted" for reload.
No violations or deviatinns were identified.
5.
