Enclosure SUMMARY OF FINDINGS
IR 05000280/2010004, 05000281/2010004, 05000280/2010501, and 05000281/2010501; 07/01/2010 - 09/30/2010; Surry Power Station, Units 1 and 2, Routine Integrated Inspection Report
The report covered a 3 month period of inspection by resident inspectors and an announced emergency preparedness inspection by regional specialists. The significance of most findings is indicated by their color (Green, White, Yellow, Red) using Inspection Manual Chapter (IMC) 0609, "Significance Determination Process" (SDP). The cross-cutting aspect was determined
using IMC 0310, "Components Within The Cross-Cutting Areas." Findings for which the SDP does not apply may be Green or be assigned a severity level after NRC management review. The NRC's program for overseeing the safe operation of commercial nuclear power reactors is described in NUREG-1649, "Reactor Oversight Process" Revision 4, dated December 2006.
NRC Identified and Self-Revealing Findings
None
Licensee Identified Violations
A violation of very low safety significance that was identified by the licensee has been reviewed
by the inspectors. Corrective actions taken or planned by the licensee have been entered into the licensee's corrective action program. This violation and corrective action tracking numbers are listed in Section 4OA7 of this report.
Enclosure REPORT DETAILS
Summary of Plant Status
Unit 1 operated at or near full rated thermal power (RTP) throughout the inspection period.
Unit 2 entered the period at full power. A forced outage was conducted from July 11 - 13 to repair a non-isolable leak in the circulating water pipe supplying the 2A condenser water box. The reactor was brought critical following the repair on July 13, however due to a voltage spike on the main generator during trouble shooting of its voltage regulator, the reactor was shut
down on July 14 to inspect the Unit 2 main and station service transformers. The reactor was taken critical at 1:21 am on July 16 and the unit was later re-connected to the electrical grid. Full power was obtained the morning of July 17 and maintained until August 28 when power was reduced to 84% due to degrading condenser vacuum. The condition was promptly corrected and full power was restored for the remainder of the inspection period.

15 Enclosure performance issues for follow-up, the inspectors performed a daily screening of items entered into the licensee's CAP. This review was accomplished by reviewing daily CR report summaries and periodically attending daily CR Review Team meetings.
.2 Annual Samples - EDG #1 Failed to Start During Testing (CR 374103)
a. Inspection Scope
Based on risk significance of the Emergency A/C Power Systems and evidence of an
adverse trend associated with fail-to-start and fail-to-load events for all three emergency diesel generators and the station blackout diesel generator, CR 374103 and its associated corrective actions were selected for follow-up. The inspectors reviewed the CR and CAs against the applicable performance attributes contained in NRC inspection procedure 71152, "Problem Identification and Resolution."
b. Findings and Observations
The inspectors identified an extensive history of similar documented events, where the EDGs failed-to-start during testing, that dated back 12 years. Documented troubleshooting and cause analyses performed for each event were often sparse and lacking rigor which made assessing effectiveness of the licensee's prior corrective
actions difficult, if not impossible, to determine. The inspector, however, noted following a fail-to-start event in 2001 (S-2001-3453) on the No. 2 EDG, the licensee identified that critical relays in the EDG's starting circuits had never been replaced in 30 years of service. A corrective action was created to institute a replacement PM, on a 12-year frequency, of all critical relays in each EDG. For reasons that remain unclear, the PM
was not created and entered into the PM tracking system until 2 years later in 2003. Procurement and engineering issues resulted in further delays and in 2008 a PM deferral (S-DEF-2008-0071) re-scheduled the relay replacements to coincide with pre-planned EDG maintenance packages from 2008 through 2014. In March 2010, the No. 1 EDG failed to start during surveillance testing (CR 374103). The root cause team was
not able to establish a definitive cause for the start failure and could not rule out intermittent failure or faulty actuation of one or more relays in the start circuit; of those relays, several were original equipment, which had not yet been replaced in accordance with the established PM that was recommended in 2000. The suspect components in EDG #1 that could not be ruled out by the root cause team were replaced as well as the
remaining legacy relays present in both start circuits. Though some remain, the licensee has replaced the majority of legacy relays in the other two EDGs.
4OA3 Event Follow-up
.1 (Closed) LER 05000280/2010-003-00, Loss of Vital Bus Due to Human Error results in Automatic Reactor Trip.
On June 8, 2010 the Unit 1 120 VAC Vital Bus 1-III was lost when the uninterruptible power supply (UPS) VB 1-A2 static switch swapped from the inverter to the Regulating Line Conditioner (RLC) (the alternate AC power source), which was tagged out for on-going maintenance. The static switch from the inverter swapped because a worker
16 Enclosure dropped an energized lead during the maintenance. In response to the loss of the vital bus an automatic reactor trip occurred on Unit 1 from 100% power which was followed by a subsequent automatic safety injection. Additionally, a small fire, which was promptly extinguished, broke out in the nuclear instrumentation cabinet within the main
control room when an electrical RC filter failed. The inspectors reviewed the LER for accuracy, adequacy of corrective actions, and violation of NRC requirements. Details of the event and associated inspection findings are provided in the NRC Special Inspection Team (SIT) inspection report, IR 05000280/2010006. This LER is closed.
4OA5 Other Activities
.1 Quarterly Resident Inspector Observations of Security Personnel and Activities
a. Inspection Scope
During the inspection period, the inspectors conducted observations of security force
personnel and activities to ensure that the activities were consistent with the licensee security procedures and regulatory requirements relating to nuclear plant security. These observations took place during both normal and off-normal plant working hours.
These quarterly resident inspector observations of security force personnel and activities
did not constitute any additional inspection samples. Rather, they were considered an integral part of the inspectors' normal plant status review and inspection activities.
b. Findings
No findings were identified.
.2 (Closed) URI 05000280, 281/2009007-02, "Availability of Portable Ventilation Fans for Use by the Fire Brigade."
a. Inspection Scope
As described in Unresolved Item (URI) 05000280, 281/2009007-02, the inspectors identified issues related to the availability of portable ventilation fans for use by the fire brigade. The inspectors performed an extensive review of the licensee's fire protection
program procedures, records of completed drills, and corrective actions relating to the issues identified by the inspectors.
b. Findings and Observations
NFPA 27-1975, Section 72, "Equipment Storage," states that storage space for the brigade equipment should be provided so that it can be promptly obtained for use and be
properly maintained. The licensee committed to NFPA 27-1975 in their fire protection plan (FPP).
17 Enclosure Portable ventilation fans are needed at Surry because no special smoke exhausting systems are installed at the plant. This condition was recognized in the SER dated September 19, 1979, as evidenced by Section 4.4.1, Smoke Removal, which states that no special smoke exhausting systems are provided at the plant. It further states that
when normal ventilation systems cannot be used (for smoke removal), the fire brigade will use the portable ventilation units with flexible ducting available at the plant for smoke removal. The ability to remove smoke and provide ventilation in manual fire fighting situations is important because it can aid the fire brigade in locating the fire source quickly and it can reduce the likelihood of the formation of hot gas layers which can
damage exposed safe shutdown cabling in overhead raceways. After the licensee was made aware of the concern, the residents observed the licensee response to additional fire drills and one actual fire on July 9, 2009. The inspectors concluded, based on these observations, that the fire brigade is capable of obtaining the required smoke removal equipment within an acceptable time period.
The inspectors concluded that the failure to provide (smoke removal) brigade equipment
in a location where it can be promptly obtained for use in accordance with NFPA 27-1975 was a performance deficiency (PD). The PD was not more than of minor significance because it did not affect the fire brigade's ability to extinguish the fire within the required time. The licensee added this concern to their corrective action program as CR 343486. In response to the identified concern, the licensee purchased three
additional smoke removal units which will further improve timely access to the smoke removal equipment throughout the plant and more than doubles their smoke removal capacity. The licensee has also added the use of portable ventilation equipment to their fire brigade training. This URI is closed.
.3 Closed: Unresolved Item (URI) 05000280, 281/2010002-01, Emergency Plan Minimum Staffing The resident inspectors had previously opened URI 05000280, 281/2010002-01 in NRC Integrated Inspection Report 05000280, 281/2010002 based on maintenance of the
required minimum on-site staffing requirements in accordance with the licensee's Emergency Plan. The enforcement aspects of this finding are discussed is Section 4OA7. This URI is closed.
4OA6 Meetings, Including Exit
Exit Meeting Summary
On October 14, 2010 the inspection results were presented to Mr. Sloane and other
members of his staff, who acknowledged the findings. The inspectors asked the licensee whether any of the material examined during the inspection should be considered proprietary. No proprietary information was identified.
On September 10, 2010, the lead inspector presented the inspection results to Mr. G. Sloane and other members of his staff. The inspector confirmed that proprietary information was not provided during the inspection.
18 Enclosure On September 29, 2010, the lead inspector re-exited with Mr. G. Sloane and other members of the Surry staff via teleconference. The closure of Unresolved Item (URI) 05000280, 281/2010002-01, Emergency Plan Minimum Staffing was discussed
4OA7 Licensee-Identified Violation
The following finding of very low significance was identified by the licensee and is a violation of NRC requirements which meets the criteria of Section 2.3.2 of the NRC Enforcement Policy, NUREG-1600, for characterization as a Green Non-Cited Violation
(NCV). * 10 CFR 50.54(q) states in part that a licensee authorized to possess and operate a nuclear power reactor shall follow and maintain in effect emergency plans which meet the standards in 10 CFR 50.47(b) and the requirements in appendix E of this part. Contrary to this, between early December 2006 and January 2010, the licensee identified that the staffing was reduced for mechanical maintenance and electrical maintenance personnel on shift to below the minimum shift staffing requirements of the Emergency Plan without a 50.54(q) review. The violation was
determined to be of very low safety significance because, the licensee demonstrated non-designated coincidental coverage for the shift staffing positions in question, no degradation of the planning standard existed and the criteria for a white finding was not met. The licensee corrected the deficiency when it was discovered and entered it into the corrective action program as
condition report CR364194.
