ExitInterview(30702,30703)
The inspection scope and findings were summarized on January 30, 1987, with
those persons indicated in paragraph 1 above. The inspectors described the
areas inspected and discussed the inspection findings. The licensee did not
identify as proprietary any of the materials provided to or reviewe,d by the
inspectors during the inspection.

3.
Licensee Action on Previous Inspection Findings (92701, 92702)
(Closed) Unresolved Item 84-14-02, Adequacy of sra45er walkdown inspection.
LER 84-018, Steam _ generator system snubber and %dpa rt failures, identified
multiple snubber failures attributed to syrtEr. crr s ients.
The unresolved
item was a result of the snubber failures tir atif a in the above LER. The
inspector questioned the adequacy of the walkdown inspection following the
snubber failures.
The licensee has developed a Design Guide Procedure
ME-07, Evaldation of Technical Specification Snubbers, that provides a
,
detailed description of how an engineering evaluation shall be performed to
satisfy Technical Spcification (TS) Section 4.7.7.g.
The inspector
selected two NCN's 2082 and 2094, related to snubber failures, for review.
The NCN's were written prior to issuance of ME-07 but were dispositioned
utilizing the methods in the procedure while the procedure was in draft.
The inspector verified that the evt.luation was performed to satisfy the TS
requirements.
LER 84-018 was closed in inspection report 85-02. This item
is closed.

(Closed)
Bulletin 85-01, Steam binding of Auxiliary Feedwater (AFW) pump.
The inspector reviewed the licensee's response to items in the bulletin and
verified that the procedures required to monitor fluid conditions within the
AFW system were accomplished by the revision of the station logs on June 9,
1985.
This revision requires recording each emergency pump discharge
temperature once per eight hour shift.
Item 2 of the bulletin was satisfied
on January 2, 1986, when the Emergency Feedwater System Operating Procedure
(SOP-211) was revised to address recognition and corrective action for steam
binding of Emergency Feedwater pumps.
The inspector verified that a lesson
plan was incorporated into the training program to address the Auxiliary
Feedwater pumps disabled by back leakage. This item is closed.
(Closed)
Bulletin 85-02, Undervoltage trip attachments of Westinghouse
DB-50 type reactor trip breakers.
This bulletin is not applicable to the
V. C. Summer Station, since DS-416 type reactor trip breakers are installed,
instead of 08-50 type breakers, as addressed in this bulletin. This item is
closed.
(Closed)
Inspector Followup Item 83-15-07, Qualified reviewer problem with
technical specifications. This item addressed an inspector concern with the
qualification requirements of procedure reviewers as specified in technical
specifications.
The applicable section of ANSI Standard 18.1 (1971),
referenced in technical specifications, did not include qualifications for
procedure reviewers in the area of operations, managers and supervisors.
Amendment 57 to technical specifications, item 6.5.3.1 and item 6.5.3.1(e),
issued on December 22, 1986, corrects this discrepancy.
This item is
closed.
(Closed)
Violation 86-15-01, Failure to perform a 50.59 review prior to
implementing changes to plant operations.
The licensee provided a written
response to this violation in a letter to Region II, dated October 23, 1986.
The inspector reviewed the licensee's response and the corrective actions
implemented to prevent recurrence of this item.
The revisions to Station
Administrative Procedure (SAP-204), appear to provide adequate guidance to
plant personnel. This item is closed.
4.
Monthly Surveillance Observation (61726)
The inspectors observed surveillance activities of safety related systems
and components to ascertain that these activities were conducted in
accordance with license requirements.
The inspectors observed portions of
selected surveillance tests including all aspects of one major surveillance
test involving safety related systems.
The inspectors also verified that
the required administrative approvals
were obtained prior to initiating
the test, that the testing was accomplished by qualified personnel, that
required test instrumentation was properly calibrated, that data met TS
requirements, that test discrepancies were rectified, and that the systems
were properly returned to service.
The following specific surveillance
activities were observed:

5.
Monthly Maintenance Observation (62703)
The inspectors observed maintenance activities of safety related systems and
components to ascertain that these activities were conducted in accordance
with approved procedures, TS and appropriate industry codes and standards,
i
The inspectors also determined that the procedures used were adequate to
control the activity, and that these activities were accomplished by
qualified personnel.
The inspectors independently verified that equipment
was properly tested before being returned to service.
Additionally, the
inspectors reviewed several outstanding job orders to determine that the
licensee was giving priority to safety related maintenance and a backlog
which might affect its performance was not developing on a given system.

Operational Safety Verification (71707)
The inspectors toured the control room, reviewed plant logs, records and
held discussions with plant staff personnel to verify that the plant was
being operated safely and in conformance with applicable requirements.
Specific items inspected in the control room included:
adequacy of staffing
and attentiveness of control room personnel; TS and procedural adherence;
.
.
5
operability of equipment and indicated control room status; control room
logs, tagout books, operating orders, jumper / bypass controls; computer
printouts and annunciators.
Tours of other plant areas were conducted to
verify equipment operability; control of ignition sources and combustible
materials; the condition of fire detection and extinguishing equipment; the
control of maintenance and surveillance activities in progress; the
implementation of radiation protective controls and the physical security
plan. Tours were conducted during normal and random off hour periods.
No violations or deviations were identified.
7.
ESF System Walkdown (71710)
The inspectors verified the operability of an engineered safety features
(ESF) system by performing a walkdown of the accessible portions of the
Offsite Power System.
The inspectors confirmed that the licensee's system
lineup procedures matched plant drawings and the as-built configuration.
The inspectors looked for cquipment conditions and items that might, degrade
performance (hangers and supports were operable, housekeeping, etc.) and
inspected the interiors of electrical and instrumentation cabinets for
debris, loose material,' jumpers, evidence of rodents, etc.
The inspectors
verified that valves, including instrumentation isolation valves, were in
proper position, power was available, and valves were locked as appropriate.
The inspectors compared both local and remote position indications.
No violations or deviations were identified.
8.
Onsite Followup of Events and Subsequent Written Reports (92700, 93713,
93702)
The inspectors reviewed the following Licensee Event Reports (LER's) to
ascertain whether the licensee's review, corrective action and report of the
identified event or deficiency was in conformance with regulatory require-
ments, technical specifications, license conditions, and licensee procedures
and controls. Based upon this review the following items are closed.
LER 86-10
Charging / safety injection pump misalignment
LER 86-14
Turbine trip / reactor trip as a result of control
valve testing
No violations or deviations were identified.
9.
Cold Weather Preparations (71714)
The inspectors conducted a review of licensee cold weather preparations to
ascertain that the licensee maintained effective implementation of the
program of protective measures for extreme cold weather.
During the
inspection, the inspectors verified that the licensee had inspected systems
su:ceptible to freezing to verify the presence of heat tracing, space
. . -
6
heaters, and/or insulation; the proper setting of thermostats; and that the
heat tracing and space heating circuits were energized. The inspectors also
determined that, for systems which had been subjected to aaintenance and/or
modification during the past year, that any required protective measures
were reestablished, and during periods of prolonged shut down, that areas
that are no longer kept warm by normal plant operations are adequately
protected.
No violations or deviations were identified.
10. Semi-annual Effluent and Waste Disposal Report (84723, 84724)

reporting requirements, technical content, data collection, acceptance
criteria, and handling of deficiencies noted.
Completed report reviewed was as follows:
V.
C.
