(Section 1R05) | (Section 1R05) The inspectors identified a non-cited violation (NCV) of Unit license condition 2.F for failure to maintain adequate protection of a post-fire safe-shutdown area. Ammonia gas migrated through a floor drain, and concentrated in an area (MCC*2-E04 cubicle) at Unit 2 required to achieve and maintain hot standby and cold shutdown. The ammonia gas concentration was sufficient to impede entry into the cubicle and resulted in a degradation of FENOCs fire protection safe shutdown capabilities. The licensee took corrective actions to stage emergency breathing equipment near the area, established monitoring and mitigative actions for the ammonia gas in the cubicle, and entered the deficiency into their corrective action program. | ||
[P.1 (d)]. | |||
This finding is more than minor because it affects the licensees post-fire safe-shutdown capability and is associated with the Mitigating Systems Cornerstone and the respective attribute of external factors. Using Phase 1 and 2 of the Fire Protection Significance Determination Process, Inspection Manual Chapter (IMC)0609, Appendix F, the inspectors determined this finding was of very low safety significance because: (1) duration factor was based on less than three days, (2) fire frequency was based on a cable vault with other electrical equipment, and (3) at least one train of safe shutdown system is still available. The cause of this finding is related to the cross-cutting area of problem identification and resolution, in that timely and appropriate actions were not taken to address safety issues and adverse trends | |||

The licensee entered the issue into their corrective action program (CR 07-24074). | ||
iii | |||
The finding was more than minor because, if left uncorrected, the failure to adequately monitor turbine performance after significant maintenance could result in the TDAFW turbine being degraded without the knowledge of the licensee. The licensee has revised applicable post-maintenance test procedures and has implemented adequate turbine performance monitoring for 1FW-T-2. The inspectors determined the finding did not result in an actual loss of safety function of a system or train of equipment; therefore, the finding was considered to be of very low safety significance. | |||

Summary of Plant Status: | |||
Unit 1 began the inspection period at 100 percent power. On August 4, the unit was down-powered to 97 percent for planned main turbine control valve testing, and returned to full power later that day. On August 7, the unit was down-powered to 98 percent to maintain secondary plant parameters within specification during warm, humid, environmental conditions, and returned to full power later that day. Additional high ambient weather conditions occurred during brief summer afternoon periods on both August 8 and August 24, resulting in unit down-powers of similar magnitude. From September 1 to September 22, the unit commenced a planned end-of-cycle Tave / power coastdown (Sections 1R20, 1R23) from 100 percent power to approximately 92 percent power. From September 22 to September 24, the unit began a controlled downpower from 92 percent power to a shutdown condition, for planned refueling outage 1R18 (Section 1R20). | |||
Unit 2 began the inspection period operating at 100% power and essentially remained at full power for the inspection period. However, due to cooling tower performance associated with warm, humid, environmental conditions, the unit was manually down-powered approximately 3-5% several times throughout the inspection period to maintain secondary plant parameters within specification. Also, on July 7, the unit was down-powered to 97 percent for planned main turbine valve testing and returned to full power later that day. | Unit 2 began the inspection period operating at 100% power and essentially remained at full power for the inspection period.

The inspectors determined that elevated ammonia gas levels in a motor control cubicle (MCC) room were sufficient to impede entry into the cubicle and impact manual actions needed to achieve and maintain hot standby and cold shutdown for Unit 2. | ||
=====Description.===== | =====Description.===== | ||
On March 14, 2003, condition report (CR) 03-02972 was written to document recurrent issues concerning a strong ammonia odor in the | On March 14, 2003, condition report (CR) 03-02972 was written to document recurrent issues concerning a strong ammonia odor in the stations common access facility located on the Unit 2 turbine deck. This facility is the common access entrance to both Unit 1 and Unit 2 radiological areas. Gaseous ammonia is a normal breakdown byproduct of aqueous hydrazine, which is used for corrosion control in secondary plant water chemistry during power operation. Ammonia gas is normally discharged through the main condenser steam jet air-ejector (SJAE) off-gas system through a ventilation path that leads to the turbine building roof, where it is exhausted. | ||
The exhaust path is in close proximity to the air intake for the common access facility. A portion of the SJAE exhaust can be directed to the gaseous waste system in the primary auxiliary building (PAB). Initial corrective actions were to redirect all the ammonia gas to the gaseous waste system. These actions proved to have limited effect when the ammonia odor was detected at various locations throughout the PAB. This issue was entered into the corrective action program (CR-03-05790). | The exhaust path is in close proximity to the air intake for the common access facility.

Line 196: | Line 147: | ||
On October 14, 2003, a corrective action was approved to direct a portion of the ammonia gas back to the turbine building roof ventilation pathway through a temporary hose extension. Engineering was assigned to monitor and evaluate the new ventilation location, and determine if stage two of the ECP was feasible. Engineering monitored the performance of the temporary hose from August 6, 2004 until March 15, 2005, and determined stage two should be installed. On May 13, 2005, notification 600208949 was written to replace the temporary hose, since it had deteriorated and was torn apart. With the temporary hose torn, ammonia gas was once again drawn into the air intake of the common access point. The flowpath was once again redirected completely to the gaseous waste system. On September 19, 2005, corrective action 03-02972-08, via work order 200015715, was written to install the permanent piping. This corrective action was extended twice (6/13/2006, 1/23/2007). | On October 14, 2003, a corrective action was approved to direct a portion of the ammonia gas back to the turbine building roof ventilation pathway through a temporary hose extension.

On August 7, 2007, during a fire protection walkdown of Fire Area PA-4 and PA-5 in the PAB, inspectors detected a strong ammonia gas odor in motor control center cubicle MCC*2-E04. | On August 7, 2007, during a fire protection walkdown of Fire Area PA-4 and PA-5 in the PAB, inspectors detected a strong ammonia gas odor in motor control center cubicle MCC*2-E04. The Fire Protection Safe Shutdown Report, Addendum 29, shows that operator actions are required in MCC*2-E04 to achieve and maintain hot standby, as well as cold shutdown for a postulated fire in fire area CV-1. Upon exit from the PAB, the ammonia odor was reported to the radiation protection (RP) technician, who informed plant safety personnel. Site safety personnel obtained ammonia readings of 300 parts per million (ppm) in MCC*2-E04. CR 07-24892 was documented on August 9. | ||
Inspectors reviewed 1/2OM-53C.4A.44A.1, Rev. 17, Toxic Gas Release for toxicity limits of ammonia. It was determined that this procedure did not apply to this situation, but a short-term (less than one hour) Occupational Safety and Health Administration (OSHA) limit of 300 ppm for ammonia was identified. The eight-hour average exposure limit for ammonia is 50 ppm. | |||
Inspectors reviewed 1/2OM-53C.4A.44A.1, Rev. 17, | |||
Several actions were taken by FENOC to mitigate the ammonia concentration and re-establish access to the cubicle. Actions include staging self-contained breathing apparatus (SCBA) outside near cubicle MCC*2-E04; posting of danger signs while ammonia concentrations were high; opening the fire door to MCC*2-E04 cubicle and ventilating with temporary fans; and establishing a fire watch. These actions reduced ammonia levels to below 10 ppm. FENOC continues to monitor the cubicle. The licensee also evaluated potential equipment degradation due to high ammonia concentrations and determined the equipment to be unaffected. Inspectors determined there were no entry conditions for an emergency declaration and the licensees final assessments were appropriate. (Section 4OA3) | |||
The temporary hose at the turbine building vent continues to be used and Unit 2 operators control off-gas flow between the turbine building ventilation path and gaseous waste, as necessary, to prevent significant build-up of ammonia gas in any single location within the plant. Corrective action to install a permanent piping ventilation pathway outside of the turbine building, scheduled under order 200015715, has been re-prioritized and schedule coded to be completed by January 28, 2008. | The temporary hose at the turbine building vent continues to be used and Unit 2 operators control off-gas flow between the turbine building ventilation path and gaseous waste, as necessary, to prevent significant build-up of ammonia gas in any single location within the plant.

=====Analysis.===== | =====Analysis.===== | ||
The inspectors reviewed this finding using the guidance contained in Appendix B, | The inspectors reviewed this finding using the guidance contained in Appendix B, Issue Disposition Screening, of IMC 0612, Power Reactor Inspection Reports. The inspectors determined that the failure to maintain adequate fire protection SSD capabilities outside the control room by not implementing timely corrective actions to prevent the accumulation of toxic levels of ammonia gas in a SSD area was a performance deficiency. The degradation in post-fire SSD capability was a previously unknown weakness in FENOCs condition report evaluations. | ||
The performance deficiency was determined to be greater than minor because it is associated with the cornerstone attribute of external factors, and it affected the mitigating systems cornerstone objective to ensure the availability of systems that respond to initiating events to prevent undesirable consequences. Specifically, failure to correct the buildup of ammonia gas in the MCC*2-E04 cubicle resulted in a toxic hazard, and degraded the fire-protection defense-in-depth strategy involving operator actions relied upon for fire protection safe shutdown capability. The inspectors performed a Fire Protection SDP Phase 1 and Phase 2 screening in accordance with IMC 0609, Appendix F, Fire Protection Significance Determination Process (SDP). The inspectors assigned a degradation rating of moderate based on the feasibility to perform actions in a hazardous environment. However, the staging of SCBA equipment near MCC*2-E04 would allow for performance of the operator actions relied upon for post-fire safe shutdown, and the gas hazard would not have affected safe shutdown strategy or adversely affect action timelines. Additionally, the duration factor was based on less than three days and since a fire in area CV-1 would require this SSD method, the fire frequency was set to that of a cable vault with other electrical equipment. In addition, review of the SSD methods shows at least one train of safe shutdown equipment remaining available. This finding screened as very low safety significance (Green)because, in accordance with Appendix F, step 2.1, Independent SSD Path First Screening Assessment, the calculated delta CDF (core damage frequency) is less than the moderate degradation screening criteria from table 2.1.3 for post-fire SSD. | |||
The cause of this finding is related to the cross-cutting area of problem identification and resolution, in that timely and appropriate actions were not taken to address safety issues and adverse trends [P.1 (d)]. | |||

The inspectors identified an NCV of very low safety significance (Green) of 10 CFR Part 50, Appendix B, Criterion V, | The inspectors identified an NCV of very low safety significance (Green) of 10 CFR Part 50, Appendix B, Criterion V, Instructions, Procedures, and Drawings, for the failure to specify post-maintenance acceptance criteria for key turbine parameters after turbine overhaul, or maintenance that could affect turbine bearing performance, and prescribe adequate performance monitoring of the Unit 1 TDAFW turbine (1FW-T-2). | ||
Specifically, turbine temperatures for 1FW-T-2 were not monitored. | Specifically, turbine temperatures for 1FW-T-2 were not monitored. | ||
=====Description:===== | =====Description:===== | ||
The inspectors noted during a review of the operability | The inspectors noted during a review of the operability determination documented in CR 07-20307 and completed TDAFW surveillance tests, that turbine bearing temperature data was not recorded or available for Unit 1, but was available for Unit 2. EPRI Technical Report (TR) 1007461, Terry Turbine Maintenance Guide, AFW Application, an industry standard for this TDAFW turbine, recommends various monitoring data for evaluating and trending system operational readiness and overall performance. An oil piping temperature from the discharge side of the pump bearings was recorded during Unit 1 surveillances, because unlike Unit 2, Unit 1 does not have installed turbine bearing thermocouples. The inspectors noted that Unit 2 monitors their turbine bearing temperature during surveillances and post maintenance tests (PMT). | ||
Though the oil system is common between the pump and turbine, oil piping temperatures taken at the specified location may not accurately represent turbine performance conditions. The inspectors requested turbine temperature data from previous turbine overhauls or PMTs. Licensee personnel indicated that no turbine temperature data was available and no information was available to correlate the oil piping discharge temperatures to turbine bearing performance, which is not consistent with standard industry and vendor monitoring guidance. Engineering did provide a trend of oil piping temperatures from October 2001 through August 2007. Temperatures ranged from 81 to 114 degrees Fahrenheit; (acceptance criteria is less than 155 degrees). | |||
Following turbine overhaul or maintenance that could affect turbine bearing performance, the possibility of operating a degraded TDAFW turbine could exist without detection. The licensee offered that a significant change in TDAFW pump oil discharge temperature would necessitate further investigation and that oil sampling analysis is performed following maintenance. Oil samples did not indicate any particulate or observable water. | Following turbine overhaul or maintenance that could affect turbine bearing performance, the possibility of operating a degraded TDAFW turbine could exist without detection.

The FENOC Condition Monitoring program states, in part, that monitored parameter criteria are influenced by industry and operating experience. Also, Continuous Equipment Performance Improvement procedure guidance on monitoring parameters states, in part, to look for leading indicators that predict performance. The severity of a condition must be determined by all observed symptoms and consideration given to prior experience with similar equipment, industry standards, regulatory requirements and vendor recommendations. The inspectors concluded that post-maintenance acceptance criteria for key turbine parameters was not obtained after significant maintenance and that performance monitoring of 1FW-T-2 was not adequate to ensure that key turbine parameters were reasonably monitored and evaluated, considering industry standards and vendor recommendations. | The FENOC Condition Monitoring program states, in part, that monitored parameter criteria are influenced by industry and operating experience.

The inspectors determined the finding impacted the equipment performance attribute of the Mitigating Systems Cornerstone and impacted the objective to ensure the reliability of systems that respond to initiating events because , if left uncorrected, the failure to adequately monitor turbine performance following significant maintenance could result in the TDAFW turbine being degraded without the knowledge of the licensee. | The inspectors determined the finding impacted the equipment performance attribute of the Mitigating Systems Cornerstone and impacted the objective to ensure the reliability of systems that respond to initiating events because , if left uncorrected, the failure to adequately monitor turbine performance following significant maintenance could result in the TDAFW turbine being degraded without the knowledge of the licensee. | ||
Using IMC 0609, Appendix A, | Using IMC 0609, Appendix A, Determining the Significance of Reactor Inspection Findings for At-Power Situations, Attachment 1, SDP Phase 1 Screening Worksheet for IE, MS, and B Cornerstones, the inspectors determined that the finding did not result in an actual loss of safety function of a system or train of equipment. Therefore, the finding was considered to be of very low safety significance (Green). Adequate monitoring exists for the Unit 2 TDAFW turbine which demonstrates that this issue is not indicative of current plant performance. No cross-cutting aspect was identified for this finding. | ||

1. Fire in Beaver Valley Station Switchyard - July 28 - Unit 1 & Unit 2: | |||
Inspectors responded to a fire that occurred in the stations switchyard at 4:05PM on July 28. The fire was caused by a failed B phase and subsequent insulator failure on oil-circuit breaker 98 (OCB-98). The station fire brigade and local fire department responded to the fire. The fire did not affect any safety related equipment or off-site power to the station. The fire was completely extinguished at 5:47PM. The inspectors also reviewed the initial licensee notification to verify that it met the requirements specified in NUREG-1022, Event Reporting Guidelines. | |||
Inspectors | 2. Ammonia Odor in electrical cubicle MCC*2-E04 - August 7-9 - Unit 2: | ||
Inspectors evaluated FENOCs response to a strong ammonia odor that was identified in motor control cubicle (MCC) MCC*2-E04 located in the Unit 2 Auxiliary Building 755 elevation. The odor originated from the main condenser air ejector discharge that was routed via the gaseous waste system. There is a common floor drain system that connects to the MCC cubicle loop seal. Ammonia gas is a normal by-product of hydrazine during plant operations. Hydrazine is used for secondary plant corrosion control. | |||
In response to the strong ammonia odor, operators took action to re-align the discharge of the air ejectors to an approved alternate path (turbine building vent). | |||
This was performed under procedural guidance. Operations and safety personnel posted local danger signs and staged self-contained breathing apparatus (SCBA)outside the MCC cubicle in case immediate entry was required. Air samples were taken in the MCC cubicle by the station safety-specialist. The inspectors reviewed Abnormal Operating Procedures and Emergency Action Levels (EALs) and determined that no emergency declaration was warranted. Also, the inspectors interviewed plant personnel, reviewed shift narrative logs, procedures, printouts and other documents. The event was entered into the corrective action program as CR 07-24892, CR 07-25046 and CR 07-25075. (section 1R05) | |||
===3. Failure of Normal Switchgear Fan - August 15 - Unit 2:=== | |||
Inspectors observed station response to a report of smoke in the main feed water regulator valve room, adjacent to the service building. The source of the smoke was from the non-safety normal switchgear ventilation fan 2HVZ-FN217. The fire brigade was assembled. The inspectors noted licensee response to be prompt and with appropriate protective gear. Operators promptly secured fan 2HVZ-FN217 which secured the fan from smoking. There was no observable fire and the smoke rapidly dissipated. Based on EAL review, no emergency declaration was warranted. | |||
Appropriate compensatory actions were established for ventilation, fire protection, and equipment operation. The licensee determined that the fan had failed. The inspectors reviewed shift narrative logs, printouts and other documents, and interviewed plant employees. The event was entered into the corrective action program as CR 07-25174. | Appropriate compensatory actions were established for ventilation, fire protection, and equipment operation.

UNITED STATES NUCLEAR REGULATORY COMMISSION ber 9, 2007
SUBJECT:
BEAVER VALLEY POWER STATION - NRC INTEGRATED INSPECTION REPORT 05000334/2007004 AND 05000412/2007004
Dear Mr. Sena:
On September 30, 2007, the United States Nuclear Regulatory Commission (NRC) completed an inspection at your Beaver Valley Power Station Units 1 and 2. The enclosed integrated inspection report documents the inspection findings, which were discussed on October 30, 2007, with you and other members of your staff.
The inspection examined activities conducted under your license as they relate to safety and compliance with the Commission=s rules and regulations and with the conditions of your license.
The inspectors reviewed selected procedures and records, observed activities, and interviewed personnel.
Based on the results of this inspection, this report documents two (2) NRC-identified findings of very low safety significance (Green).

The report covered a 3-month period of inspection by resident inspectors, regional reactor inspectors, and a regional health physics inspector. Two (GREEN) non-cited violations (NCVs)were identified. The significance of most findings is indicated by their color (Green, White,
Yellow, Red) using Inspection Manual Chapter (IMC) 0609, ASignificance Determination Process@ (SDP). 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, AReactor Oversight Process,@ Revision 3 dated July 2000.
NRC-Identified and Self-Revealing Findings
Cornerstone: Mitigating Systems
- Green.
(Section 1R05) The inspectors identified a non-cited violation (NCV) of Unit license condition 2.F for failure to maintain adequate protection of a post-fire safe-shutdown area. Ammonia gas migrated through a floor drain, and concentrated in an area (MCC*2-E04 cubicle) at Unit 2 required to achieve and maintain hot standby and cold shutdown. The ammonia gas concentration was sufficient to impede entry into the cubicle and resulted in a degradation of FENOCs fire protection safe shutdown capabilities. The licensee took corrective actions to stage emergency breathing equipment near the area, established monitoring and mitigative actions for the ammonia gas in the cubicle, and entered the deficiency into their corrective action program.
This finding is more than minor because it affects the licensees post-fire safe-shutdown capability and is associated with the Mitigating Systems Cornerstone and the respective attribute of external factors. Using Phase 1 and 2 of the Fire Protection Significance Determination Process, Inspection Manual Chapter (IMC)0609, Appendix F, the inspectors determined this finding was of very low safety significance because: (1) duration factor was based on less than three days, (2) fire frequency was based on a cable vault with other electrical equipment, and (3) at least one train of safe shutdown system is still available. The cause of this finding is related to the cross-cutting area of problem identification and resolution, in that timely and appropriate actions were not taken to address safety issues and adverse trends
[P.1 (d)].
Cornerstone: Mitigating Systems
- Green.
(Section 4OA2) The inspectors identified a non-cited violation of 10 CFR Part 50, Appendix B, Criterion V, Instructions, Procedures, and Drawings, for the failure to specify post-maintenance acceptance criteria for important turbine parameters after turbine overhaul, or maintenance that could affect turbine bearing performance, and prescribe adequate performance monitoring of the Unit 1 turbine-driven auxiliary feedwater (TDAFW) turbine (1FW-T-2). The licensee entered the issue into their corrective action program (CR 07-24074).
iii
The finding was more than minor because, if left uncorrected, the failure to adequately monitor turbine performance after significant maintenance could result in the TDAFW turbine being degraded without the knowledge of the licensee. The licensee has revised applicable post-maintenance test procedures and has implemented adequate turbine performance monitoring for 1FW-T-2. The inspectors determined the finding did not result in an actual loss of safety function of a system or train of equipment; therefore, the finding was considered to be of very low safety significance.

REPORT DETAILS
Summary of Plant Status:
Unit 1 began the inspection period at 100 percent power. On August 4, the unit was down-powered to 97 percent for planned main turbine control valve testing, and returned to full power later that day. On August 7, the unit was down-powered to 98 percent to maintain secondary plant parameters within specification during warm, humid, environmental conditions, and returned to full power later that day. Additional high ambient weather conditions occurred during brief summer afternoon periods on both August 8 and August 24, resulting in unit down-powers of similar magnitude. From September 1 to September 22, the unit commenced a planned end-of-cycle Tave / power coastdown (Sections 1R20, 1R23) from 100 percent power to approximately 92 percent power. From September 22 to September 24, the unit began a controlled downpower from 92 percent power to a shutdown condition, for planned refueling outage 1R18 (Section 1R20).
Unit 2 began the inspection period operating at 100% power and essentially remained at full power for the inspection period. However, due to cooling tower performance associated with warm, humid, environmental conditions, the unit was manually down-powered approximately 3-5% several times throughout the inspection period to maintain secondary plant parameters within specification. Also, on July 7, the unit was down-powered to 97 percent for planned main turbine valve testing and returned to full power later that day.

b. Findings
Introduction.
The inspectors identified an NCV of very low safety significance (green) of Unit 2 license condition 2.F, Fire Protection Program, for failure to maintain adequate fire protection safe shutdown (SSD) capabilities outside the control room. The inspectors determined that elevated ammonia gas levels in a motor control cubicle (MCC) room were sufficient to impede entry into the cubicle and impact manual actions needed to achieve and maintain hot standby and cold shutdown for Unit 2.
Description.
On March 14, 2003, condition report (CR) 03-02972 was written to document recurrent issues concerning a strong ammonia odor in the stations common access facility located on the Unit 2 turbine deck. This facility is the common access entrance to both Unit 1 and Unit 2 radiological areas. Gaseous ammonia is a normal breakdown byproduct of aqueous hydrazine, which is used for corrosion control in secondary plant water chemistry during power operation. Ammonia gas is normally discharged through the main condenser steam jet air-ejector (SJAE) off-gas system through a ventilation path that leads to the turbine building roof, where it is exhausted.
The exhaust path is in close proximity to the air intake for the common access facility. A portion of the SJAE exhaust can be directed to the gaseous waste system in the primary auxiliary building (PAB). Initial corrective actions were to redirect all the ammonia gas to the gaseous waste system. These actions proved to have limited effect when the ammonia odor was detected at various locations throughout the PAB. This issue was entered into the corrective action program (CR-03-05790).
Engineering Change Package (ECP) 03-0262 was developed to relocate the turbine building vent stack away from the air intakes. This was to be accomplished in two stages. The first stage was to use a temporary hose attached to the turbine building vent with the intention of determining the optimal location to install a permanent hard pipe.
The second stage would be to install the hard pipe.
On October 14, 2003, a corrective action was approved to direct a portion of the ammonia gas back to the turbine building roof ventilation pathway through a temporary hose extension. Engineering was assigned to monitor and evaluate the new ventilation location, and determine if stage two of the ECP was feasible. Engineering monitored the performance of the temporary hose from August 6, 2004 until March 15, 2005, and determined stage two should be installed. On May 13, 2005, notification 600208949 was written to replace the temporary hose, since it had deteriorated and was torn apart. With the temporary hose torn, ammonia gas was once again drawn into the air intake of the common access point. The flowpath was once again redirected completely to the gaseous waste system. On September 19, 2005, corrective action 03-02972-08, via work order 200015715, was written to install the permanent piping. This corrective action was extended twice (6/13/2006, 1/23/2007).
On August 7, 2007, during a fire protection walkdown of Fire Area PA-4 and PA-5 in the PAB, inspectors detected a strong ammonia gas odor in motor control center cubicle MCC*2-E04. The Fire Protection Safe Shutdown Report, Addendum 29, shows that operator actions are required in MCC*2-E04 to achieve and maintain hot standby, as well as cold shutdown for a postulated fire in fire area CV-1. Upon exit from the PAB, the ammonia odor was reported to the radiation protection (RP) technician, who informed plant safety personnel. Site safety personnel obtained ammonia readings of 300 parts per million (ppm) in MCC*2-E04. CR 07-24892 was documented on August 9.
Inspectors reviewed 1/2OM-53C.4A.44A.1, Rev. 17, Toxic Gas Release for toxicity limits of ammonia. It was determined that this procedure did not apply to this situation, but a short-term (less than one hour) Occupational Safety and Health Administration (OSHA) limit of 300 ppm for ammonia was identified. The eight-hour average exposure limit for ammonia is 50 ppm.
Several actions were taken by FENOC to mitigate the ammonia concentration and re-establish access to the cubicle. Actions include staging self-contained breathing apparatus (SCBA) outside near cubicle MCC*2-E04; posting of danger signs while ammonia concentrations were high; opening the fire door to MCC*2-E04 cubicle and ventilating with temporary fans; and establishing a fire watch. These actions reduced ammonia levels to below 10 ppm. FENOC continues to monitor the cubicle. The licensee also evaluated potential equipment degradation due to high ammonia concentrations and determined the equipment to be unaffected. Inspectors determined there were no entry conditions for an emergency declaration and the licensees final assessments were appropriate. (Section 4OA3)
The temporary hose at the turbine building vent continues to be used and Unit 2 operators control off-gas flow between the turbine building ventilation path and gaseous waste, as necessary, to prevent significant build-up of ammonia gas in any single location within the plant. Corrective action to install a permanent piping ventilation pathway outside of the turbine building, scheduled under order 200015715, has been re-prioritized and schedule coded to be completed by January 28, 2008.
Analysis.
The inspectors reviewed this finding using the guidance contained in Appendix B, Issue Disposition Screening, of IMC 0612, Power Reactor Inspection Reports. The inspectors determined that the failure to maintain adequate fire protection SSD capabilities outside the control room by not implementing timely corrective actions to prevent the accumulation of toxic levels of ammonia gas in a SSD area was a performance deficiency. The degradation in post-fire SSD capability was a previously unknown weakness in FENOCs condition report evaluations.
The performance deficiency was determined to be greater than minor because it is associated with the cornerstone attribute of external factors, and it affected the mitigating systems cornerstone objective to ensure the availability of systems that respond to initiating events to prevent undesirable consequences. Specifically, failure to correct the buildup of ammonia gas in the MCC*2-E04 cubicle resulted in a toxic hazard, and degraded the fire-protection defense-in-depth strategy involving operator actions relied upon for fire protection safe shutdown capability. The inspectors performed a Fire Protection SDP Phase 1 and Phase 2 screening in accordance with IMC 0609, Appendix F, Fire Protection Significance Determination Process (SDP). The inspectors assigned a degradation rating of moderate based on the feasibility to perform actions in a hazardous environment. However, the staging of SCBA equipment near MCC*2-E04 would allow for performance of the operator actions relied upon for post-fire safe shutdown, and the gas hazard would not have affected safe shutdown strategy or adversely affect action timelines. Additionally, the duration factor was based on less than three days and since a fire in area CV-1 would require this SSD method, the fire frequency was set to that of a cable vault with other electrical equipment. In addition, review of the SSD methods shows at least one train of safe shutdown equipment remaining available. This finding screened as very low safety significance (Green)because, in accordance with Appendix F, step 2.1, Independent SSD Path First Screening Assessment, the calculated delta CDF (core damage frequency) is less than the moderate degradation screening criteria from table 2.1.3 for post-fire SSD.
The cause of this finding is related to the cross-cutting area of problem identification and resolution, in that timely and appropriate actions were not taken to address safety issues and adverse trends [P.1 (d)].
Enforcement.
Unit 2 Operating License Condition 2.F requires the fire protection program to be implemented and maintained in accordance with the requirements of section 9.5 of the FSAR, as amended. Contrary to the above, FENOC failed to take timely corrective action to eliminate high ammonia gas concentrations in the Auxiliary Building resulting in a degraded fire protection safe-shutdown capability. Because this finding is of low safety significance and has been entered into FENOCs corrective action program as CR 07-25046, this violation is being treated as an NCV, consistent with section VI.A.1 of the NRC Enforcement Policy. (NCV 05000412/2007004-01, Post-Fire Safe Shutdown Capability Degraded due to Ammonia Gas Hazard)
.2 Annual Fire Drill Observation
a. Inspection Scope
(1 sample)
The inspectors observed personnel performance during a fire brigade drill on August 5, to evaluate the readiness of station personnel to prevent and fight fires. The drill simulated a fire in the Unit 2 Condensate Polishing Filter Banks on level 773. The inspectors observed the fire brigade members using protective clothing, turnout gear, self-contained breathing apparatus, and entering the fire area in a controlled manner.
The inspectors also observed the fire fighting equipment brought to the fire scene to evaluate whether sufficient equipment was available to effectively control and extinguish the simulated fire. The inspectors evaluated whether the permanent plant fire hose lines were capable of reaching the fire area and whether hose usage was adequately simulated. The inspectors observed the fire fighting directions and communications between fire brigade members. The inspectors verified that the pre-planned drill scenario was followed and observed the post drill critique to evaluate if the drill objectives were satisfied and that any drill weaknesses were discussed.
b. Findings
No findings of significance were identified.
1R11 Licensed Operator Requalification Program
.1 Resident Inspector Quarterly Review
a. Inspection Scope
(1 sample)

The inspectors evaluated licensed operator performance regarding command and control, implementation of normal, annunciator response, abnormal, and emergency operating procedures, communications, technical specification review and compliance, and emergency plan implementation. The inspectors evaluated the licensee staff training personnel to verify that deficiencies in operator performance were identified, and that conditions adverse to quality were entered into the licensee=s corrective action program for resolution. The inspectors reviewed simulator physical fidelity to assure the simulator appropriately modeled the plant control room. The inspectors verified that the training evaluators adequately addressed whether the applicable training objectives had been achieved. Documents reviewed are listed in the Attachment.
b. Findings
No findings of significance were identified.
.2 Biennial Review by Regional Specialist
a. Inspection Scope
The following inspection activities were performed using NUREG 1021, Rev. 9, Operator Licensing Examination Standards for Power Reactors, Inspection Procedure Attachment
===71111.11, Licensed Operator Requalification Program, Appendix A Checklist for Evaluating Facility Testing Material, and Appendix B Suggested Interview Topics.
The inspectors reviewed documentation of operating history since the last requalification program inspection. The inspectors also discussed facility operating events with the resident staff. Documents reviewed included NRC inspection reports, and licensee condition reports (CRs) that involved human performance issues for licensed operators to ensure that operational events were not indicative of possible training deficiencies.
The inspectors reviewed two comprehensive written exams, and the scenarios and job performance measures administered during the weeks of June 18 and 25 to ensure the quality of these exams met or exceeded the criteria established in the Examination Standards and 10 CFR 55.59. The inspectors observed the administration of the operating exams to two crews.
Conformance with Simulator Requirements Specified in 10 CFR 55.46 The inspectors observed simulator performance during the conduct of the examinations, and reviewed simulator discrepancy reports to verify facility staff were complying with the requirements of 10 CFR 55.46. The inspectors reviewed a sample of simulator tests including transients, normal, steady state, malfunction as well as core performance tests.
Inspectors also verified that a sample of completed simulator work requests (SWRs)from the past two-year period effectively addressed the described issue.
Conformance with operator license conditions was verified by reviewing the following records:
Six medical records (four for Unit 2; two for Unit 1). All records were complete; restrictions noted by the doctor were reflected on the individuals license; and physical exams were given within 24 months.
$ One proficiency watch-standing and two reactivation records. Records indicated the licensed operators conformed with proficiency and reactivation watch-standing requirements of 10 CFR 55.53.
$ Remediation training records for two licensed operators. These operators had failed their previous annual operating tests. The remediation records were acceptable.
Licensees Feedback System. The inspectors interviewed instructors, training and operations management personnel, and three licensed operators for feedback regarding the implementation of the licensed operator requalification program to ensure the requalification program was meeting their needs and was responsive to their recommended changes.
On August 31, 2007, the inspectors conducted an in-office review of licensee requalification exam results. These results included the annual operating tests and the comprehensive written exams administered this year. The inspection assessed whether pass rates were consistent with the guidance of NRC Manual Chapter 0609, Appendix I, Operator Requalification Human Performance Significance Determination Process (SDP). The inspectors verified that:
$ Crew failure rate on the dynamic simulator was less than 20%. (Failure rate was 0.0%)
$ Individual failure rate on the dynamic simulator test was less than or equal to 20%. (Failure rate was 0.0%)
$ Individual failure rate on the walkthrough test (JPMs) was less than or equal to 20%. (Failure rate was 0.0%)
$ Individual failure rate on the comprehensive written exam was less than or equal to 20%. (Failure rate was 5.0%)
$ More than 75% of the individuals passed all portions of the exam (95% of the individuals passed all portions of the exam).

During the period July 9 - 13, 2007, the inspector conducted the following activities to verify that the licensee implemented the radiological environmental monitoring program (REMP) consistent with the Technical Specifications (TS) and the Off-Site Dose Calculation Manual (ODCM) to validate that radioactive effluent releases met the design objectives of Appendix I to 10 CFR 50.
Additionally, the inspector verified that radiological surveys and controls were adequate to prevent the inadvertent release of radioactive material into the public domain.
Implementation of these controls was reviewed against the criteria contained in 10 CFR 20 & 50, relevant TS and the licensees procedures.
This inspection activity represents completion of ten
- (10) samples relative to this inspection area.
REMP Inspections:
$ The inspector reviewed the 2006 Annual Radiological Environmental Operating Report and the 2006 REMP Land Use Census Report to verify that the environmental monitoring programs were implemented as required by the ODCM (Revision 6).
$ The inspector walked down five (of 10) air sampling stations (Nos. 28, 29B, 32, 46.1, 47), four (of 6) milk sampling stations (Nos. 25, 69, 96, 113), three (of 3)surface water sampling stations (Nos. 2.1, 5, 49), two (of 2) drinking water stations (Nos. 14, 15), and 22 (of 44) thermoluminescent (TLD) monitoring stations (See Attachment A) to determine if sampling was conducted as described in the ODCM, and to evaluate the sampling equipment material condition.
$ As part of the walkdown, the inspector observed the technician collect and prepare for analysis air particulate/iodine filter samples, milk samples, water samples, and TLDs; and verified that environmental sampling was representative of the release pathways as specified in the ODCM, and that sampling techniques were in accordance with procedures.
$ Based on direct observation and review of records, the inspector verified that the meteorological instrumentation was operable, calibrated, and maintained in accordance with the guidance contained in the FSAR, NRC Safety Guide 23, and the licensee procedures. The inspector verified that the meteorological data readout and recording instruments in the control room and at the tower were operable for wind direction, wind speed, and delta temperature. The inspector confirmed that redundant instrumentation was available for channels taken out of service for repair.
$ The inspector reviewed the calibration records for ten
- (10) air samplers and observed the technician verifying the calibration of three water compositors.
$ The inspector reviewed Condition Reports, a Nuclear Oversight Assessment Report (BV-C-05-02), and a Nuclear Oversight Field Observation report (BV320052197), relevant to the REMP requirements, to evaluate the threshold for which issues are entered into the corrective action program, the adequacy of subsequent evaluations, and the effectiveness of the resolution. The inspector also reviewed monthly RETS/ODCM effluent occurrence reports to evaluate the adequacy and timeliness of performance indicator information.
$ The inspector reviewed the results of the licensees quarterly laboratory cross-check program to verify the accuracy of the licensees environmental air filter, charcoal cartridge, water, and milk sample analyses.
$ The inspector reviewed any significant changes made by the licensee to the ODCM as a result of changes to the land use census or sampler station modifications since the last inspection. The inspector also reviewed technical justifications for any change in sampling location (or frequency) and verified the licensee performed the reviews required to ensure that the changes did not affect its ability to monitor the radiological condition of the environment.
Unrestricted Release of Material from the Radiologically Controlled Area (RCA)
$ The inspector observed several locations in Units 1 and 2, including the Health Physics Main Control Point, the Decontamination Facility, and the Site Tool Facility, where the licensee monitors potentially contaminated material leaving the RCA, and inspected methods used for control, survey, and release from these areas, including observing the performance of personnel surveying and releasing material for unrestricted use. With the assistance of a technician, the inspector verified that the Small Article Monitors (SAM) alarmed when a check source was counted.
$ The inspector verified that the radiation monitoring instrumentation (SAM-9, SAM-11, Frisker) was appropriate for the radiation types potentially present and was calibrated with appropriate radiation sources. The inspector reviewed the licensees criteria for the survey and release of potentially contaminated material; verified that there was guidance on how to respond to an alarm which indicates the presence of contamination; and reviewed instrument alarm setpoints to ensure that radiation detection sensitivities are consistent with the NRC guidance contained in IE Circular 81-07 and IE Information Notice 85-92 for surface contamination and HPPOS-221 for volumetrically contaminated material. The inspector also reviewed the licensees procedures and records to verify that the radiation detection instrumentation was used at its typical sensitivity level based on appropriate counting parameters, and verified that the licensee has not established a release limit by altering the instruments sensitivity through such methods as raising the energy discrimination level or locating the instrument in a high radiation background area.

.5 Inspection Module Problem Identification and Resolution (PI&R) Review
a. Inspection Scope
The inspectors reviewed various CRs associated with the inspection activities captured in each inspection module of this report. Specific focus was placed on CR 07-20307, documenting a high oil level in the outboard turbine bearing for the TDAFW pump. In addition, related CR 06-05216 was reviewed.
b. Findings
Introduction:
The inspectors identified an NCV of very low safety significance (Green) of 10 CFR Part 50, Appendix B, Criterion V, Instructions, Procedures, and Drawings, for the failure to specify post-maintenance acceptance criteria for key turbine parameters after turbine overhaul, or maintenance that could affect turbine bearing performance, and prescribe adequate performance monitoring of the Unit 1 TDAFW turbine (1FW-T-2).
Specifically, turbine temperatures for 1FW-T-2 were not monitored.
Description:
The inspectors noted during a review of the operability determination documented in CR 07-20307 and completed TDAFW surveillance tests, that turbine bearing temperature data was not recorded or available for Unit 1, but was available for Unit 2. EPRI Technical Report (TR) 1007461, Terry Turbine Maintenance Guide, AFW Application, an industry standard for this TDAFW turbine, recommends various monitoring data for evaluating and trending system operational readiness and overall performance. An oil piping temperature from the discharge side of the pump bearings was recorded during Unit 1 surveillances, because unlike Unit 2, Unit 1 does not have installed turbine bearing thermocouples. The inspectors noted that Unit 2 monitors their turbine bearing temperature during surveillances and post maintenance tests (PMT).
Though the oil system is common between the pump and turbine, oil piping temperatures taken at the specified location may not accurately represent turbine performance conditions. The inspectors requested turbine temperature data from previous turbine overhauls or PMTs. Licensee personnel indicated that no turbine temperature data was available and no information was available to correlate the oil piping discharge temperatures to turbine bearing performance, which is not consistent with standard industry and vendor monitoring guidance. Engineering did provide a trend of oil piping temperatures from October 2001 through August 2007. Temperatures ranged from 81 to 114 degrees Fahrenheit; (acceptance criteria is less than 155 degrees).
Following turbine overhaul or maintenance that could affect turbine bearing performance, the possibility of operating a degraded TDAFW turbine could exist without detection. The licensee offered that a significant change in TDAFW pump oil discharge temperature would necessitate further investigation and that oil sampling analysis is performed following maintenance. Oil samples did not indicate any particulate or observable water.
However, investigation summary for CR 07-20307 identifies leakage past the carbon shaft seals and/or the existing outboard gland leak as apparent causes of the high oil level in the turbine bearing sight glass.
The vendor technical manual recommends obtaining stable turbine bearing and oil temperatures on initial startup after overhaul. Also, EPRI Technical Report (TR)
===1007461, Terry Turbine Maintenance Guide, AFW Application, an industry standard for this TDAFW turbine, recommends various monitoring data points for evaluating and trending system operational readiness and overall performance.
The FENOC Condition Monitoring program states, in part, that monitored parameter criteria are influenced by industry and operating experience. Also, Continuous Equipment Performance Improvement procedure guidance on monitoring parameters states, in part, to look for leading indicators that predict performance. The severity of a condition must be determined by all observed symptoms and consideration given to prior experience with similar equipment, industry standards, regulatory requirements and vendor recommendations. The inspectors concluded that post-maintenance acceptance criteria for key turbine parameters was not obtained after significant maintenance and that performance monitoring of 1FW-T-2 was not adequate to ensure that key turbine parameters were reasonably monitored and evaluated, considering industry standards and vendor recommendations.
The inspectors determined the failure to specify post-maintenance acceptance criteria for key turbine parameters after turbine overhaul or maintenance that could affect turbine bearing performance and prescribe adequate performance monitoring to assess the performance of the TDAFW turbine at Unit 1 was a performance deficiency that warranted a significance evaluation in accordance with IMC 0612, Power Reactor Inspection Reports, Appendix B, Issue Screening.
Analysis:
The inspectors determined the finding impacted the equipment performance attribute of the Mitigating Systems Cornerstone and impacted the objective to ensure the reliability of systems that respond to initiating events because , if left uncorrected, the failure to adequately monitor turbine performance following significant maintenance could result in the TDAFW turbine being degraded without the knowledge of the licensee.
Using IMC 0609, Appendix A, Determining the Significance of Reactor Inspection Findings for At-Power Situations, Attachment 1, SDP Phase 1 Screening Worksheet for IE, MS, and B Cornerstones, the inspectors determined that the finding did not result in an actual loss of safety function of a system or train of equipment. Therefore, the finding was considered to be of very low safety significance (Green). Adequate monitoring exists for the Unit 2 TDAFW turbine which demonstrates that this issue is not indicative of current plant performance. No cross-cutting aspect was identified for this finding.
Enforcement:
10 CFR Part 50, Appendix B, Criterion V, requires, in part, that activities affecting quality be prescribed by documented instructions or procedures of a type appropriate to the circumstances and include appropriate quantitative or qualitative acceptance criteria to determine that important activities were satisfactorily accomplished. Contrary to the above, the licensee did not specify post-maintenance acceptance criteria for key turbine parameters after turbine overhaul, or maintenance that could affect turbine bearing performance, and prescribe adequate performance monitoring to assess the performance of the TDAFW turbine at Unit 1. Because of the very low safety significance of this finding and because the finding was entered into the licensees corrective action program as CR 07-24074, this violation is being treated as an NCV, consistent with Section VI.A.1 of the NRC Enforcement Policy. (NCV 05000334/2007004-02, Inadequate Procedure and Monitoring Program for Turbine-Driven Auxiliary Feedwater Pump Turbine, 1FW-T-2)
4OA3 Followup of Events and Notices of Enforcement Discretion
a. Inspection Scope
=
The inspectors responded to and reviewed licensee actions to three events. The inspectors observed operations in the control room and station. Applicable operating and alarm response procedures, technical specifications, plant process computer indications, and control room shift logs were reviewed to evaluate the adequacy of FENOC's response to these events. The inspectors also verified the events were entered into the corrective action program to resolve identified adverse conditions.
Documents reviewed during the inspection are listed in the Attachment.
1. Fire in Beaver Valley Station Switchyard - July 28 - Unit 1 & Unit 2:
Inspectors responded to a fire that occurred in the stations switchyard at 4:05PM on July 28. The fire was caused by a failed B phase and subsequent insulator failure on oil-circuit breaker 98 (OCB-98). The station fire brigade and local fire department responded to the fire. The fire did not affect any safety related equipment or off-site power to the station. The fire was completely extinguished at 5:47PM. The inspectors also reviewed the initial licensee notification to verify that it met the requirements specified in NUREG-1022, Event Reporting Guidelines.
2. Ammonia Odor in electrical cubicle MCC*2-E04 - August 7-9 - Unit 2:
Inspectors evaluated FENOCs response to a strong ammonia odor that was identified in motor control cubicle (MCC) MCC*2-E04 located in the Unit 2 Auxiliary Building 755 elevation. The odor originated from the main condenser air ejector discharge that was routed via the gaseous waste system. There is a common floor drain system that connects to the MCC cubicle loop seal. Ammonia gas is a normal by-product of hydrazine during plant operations. Hydrazine is used for secondary plant corrosion control.
In response to the strong ammonia odor, operators took action to re-align the discharge of the air ejectors to an approved alternate path (turbine building vent).
This was performed under procedural guidance. Operations and safety personnel posted local danger signs and staged self-contained breathing apparatus (SCBA)outside the MCC cubicle in case immediate entry was required. Air samples were taken in the MCC cubicle by the station safety-specialist. The inspectors reviewed Abnormal Operating Procedures and Emergency Action Levels (EALs) and determined that no emergency declaration was warranted. Also, the inspectors interviewed plant personnel, reviewed shift narrative logs, procedures, printouts and other documents. The event was entered into the corrective action program as CR 07-24892, CR 07-25046 and CR 07-25075. (section 1R05)
3. Failure of Normal Switchgear Fan - August 15 - Unit 2:
Inspectors observed station response to a report of smoke in the main feed water regulator valve room, adjacent to the service building. The source of the smoke was from the non-safety normal switchgear ventilation fan 2HVZ-FN217. The fire brigade was assembled. The inspectors noted licensee response to be prompt and with appropriate protective gear. Operators promptly secured fan 2HVZ-FN217 which secured the fan from smoking. There was no observable fire and the smoke rapidly dissipated. Based on EAL review, no emergency declaration was warranted.
Appropriate compensatory actions were established for ventilation, fire protection, and equipment operation. The licensee determined that the fan had failed. The inspectors reviewed shift narrative logs, printouts and other documents, and interviewed plant employees. The event was entered into the corrective action program as CR 07-25174.
b. Findings
No findings of significance were identified.
