| ENS 55299 | 9 June 2021 15:15:00 | 10 CFR 50.72(b)(2)(xi), Notification to Government Agency or News Release | Loss of Capability to Activate Emergency Sirens and Offsite Notification of Same | At 1115 EDT on June 9, 2021, during a siren activation test, a loss of the capability to activate the sirens from both Surry local activation sites was identified. The Virginia EOC was participating in the activation test and is aware of the issue and notified the local government authorities in the Surry EPZ of the situation. The NRC Resident has been notified of this issue. The station telecommunications department has been contacted and is aware of the issue. In the event that a radiological emergency should occur at the Surry Power Station, Primary Route Alerting procedures will be put in use by the local jurisdictions. This report is being made in accordance with 10 CFR 50.72(b)(2)(xi) and 10 CFR 50.72(b)(3)(xiii) due to notification of other state and local government agencies of the failure of the Alert & Notification system for Surry.
Surry Power Station Event Notification 55299 is being retracted based upon further evaluation. Surry has three localities (State SAU, James City, and Surry County) with access to the redundant activation trains (primary and backup systems). The actuation tests only one primary and one backup activation panel at two localities, only primary at the State SAU (Situational Awareness Unit) and back up at James City County were tested. Follow-up telecom and vendor investigation revealed that the primary server was functional from James City County that would have actuated all 71 sirens; Consequently, it was concluded that all of the sirens were fully functional from the James City primary system and there was no loss of all sirens as originally reported on 6/9/2021 (EN 55299). EN 55299 also contained a 4-hour Offsite Notification per 10 CFR 50.72(b)(2)(xi) that is unaffected. The NRC Resident Inspector has been notified. Notified R2DO (Miller). | ||

| ENS 53107 | 7 December 2017 18:01:00 | 10 CFR 50.72(b)(2)(xi), Notification to Government Agency or News Release | Offsite Notification of Groundwater Results to State and Local Agencies | This non-emergency notification is being made in accordance with 10 CFR 50.72(b)(2)(xi), any event or situation related to the protection of the environment for which notification to other government agencies has been made. Dominion Energy is in the process of informing the Virginia Department of Health, Department of Environmental Quality, Department of Emergency Management, and the Surry County Administrator of recent groundwater monitoring results at Surry Power Station in accordance with NEI 07-07, Industry Groundwater Protection Initiative (GPI). On December 6, 2017 at 1138 EST, Surry Power Station received analysis results of recent samples from the on-site groundwater monitoring program. As part of the program, 10 new groundwater monitoring wells were recently placed in service within the Protected Area to provide early detection, to better define the site's hydrology, and if necessary, to mitigate any potential leaks. The analysis results from one of the new wells indicated tritium activity level above the GPI communication threshold. Samples were re-analyzed, resulting in different values, with the highest result of 59,300 picoCuries per liter. Since each result was above the voluntary reporting threshold, Surry stakeholder communication was implemented in accordance with the NEI GPI Voluntary Communication Protocol, Criterion 2.2. There are no known active leaks at this location; however, Dominion Energy is continuing to investigate the source of the tritium and the reason for the variability in the sample results. Tritium was not detected in the on-site monitoring locations outside of the Protected Area. No tritium has been detected in the on-site and off-site drinking water wells. Since the activity is contained within the site restricted area, the health and safety of on-site personnel and members of the public are not affected. A 30-day report will be submitted to the NRC in accordance with NEI 07-07. The NRC Senior Resident Inspector has been notified. | ||
| ENS 52639 | 25 March 2017 00:00:00 | 10 CFR 50.72(b)(2)(xi), Notification to Government Agency or News Release | Virginia Deq Notified of Small Glycol Release to James River | On 03/24/2017 at approximately 1500 hours (EDT), a hydraulic line on vendor supplied cleaning equipment failed and leaked approximately 8 gallons of 65% glycol solution into the Surry Power Station Unit 2 D intake bay. Since the intake bay communicates with the James River, the State of Virginia Department of Environmental Quality (DEQ) was notified of the discharge at 2000 hours. The glycol solution is water soluble and dispersed quickly. All work stopped while the issue is being investigated and corrective actions implemented. No sheen was observed and no impact to state waters is expected to result from this issue. This non-emergency notification is being made in accordance with 10 CFR 50.72(b)(2)(xi), any event or situation related to the protection of the environment for which notification to other government agencies has been made. The NRC Senior Resident Inspector has been notified. | ||
| ENS 50418 | 29 August 2014 18:57:00 | 10 CFR 50.72(b)(2)(xi), Notification to Government Agency or News Release | Notification to State of Virginia Required by Site Discharge Permit | On 08/29/2014 at 1457 hours (EDT), Surry Power Station notified the State of Virginia Department of Environmental Quality (DEQ) that two of the three turbine building sumps, required to be sampled by the discharge permit VA00004090, indicated an out of specification condition for oil and grease parameters. The laboratory supervisor reviewed the analysis and found no discrepancies. Sample methods and sample locations were reviewed and were unchanged from previous samples. A review of the operation of the sump oil skimmers indicated that they have been operating properly. In addition, there have been no oil spills or maintenance that would cause elevated readings in the sumps. Backup samples of both sumps were obtained on 08/27/14 and 08/28/14. The results of the backup samples were received on 08/29/2014 and all samples indicated a less than the detectable levels. Based upon an initial review of the issue, the results of the backup samples, and at least 5-year history of less than detectable oil and grease levels in the sump, the original samples for the sumps are considered anomalous. The results, however, are being reported in accordance with the permit requirements. This report is being issued in accordance with 10 CFR 50.72(b)(2)(xi), any event or situation related to the protection of the environment for which notification to other government agencies has been made. The Surry NRC Senior Resident Inspector has been notified. | ||
| ENS 48860 | 28 March 2013 02:45:00 | 10 CFR 50.72(b)(2)(xi), Notification to Government Agency or News Release | One Emergency Warning Siren Energized for a Short Time | At 2245 (EDT) on 3/27/2013, Surry Power Station (SPS) Operations Department received a report from Virginia State Emergency Operations Center (VEOC) that a concerned citizen had called James City County (JCC) law enforcement to report that an Early Warning System (EWS) siren, #62 in James City County NW side of Route 682, was sounding. VEOC reported JCC police received call at 2240 (EDT) from a concerned citizen that an EWS siren was sounding. SPS Security contacted JCC police and subsequently reported that JCC police responded approximately 10 minutes later to the site of the siren, but the siren was no longer sounding. Maintenance will investigate in the morning. All plant conditions/parameters are normal and no releases to the environment have occurred. The site NRC Resident Inspectors have been notified. This notification is being transmitted due to notification of other Government Agencies in accordance with 10CFR50.72(b)(2)(xi). The licensee also notified the state and local governments.
This report is being retracted based upon the following: On 3/28/13, an activation verification test was performed. The results of the test indicated EWS siren #62 did not activate. In addition, when a siren activates, the battery voltage decreases. A review of the battery voltage trend for siren #62 found no such decrease, verifying no activation occurred. Maintenance staff reported to the siren location and confirmed the siren did not activate. They also found no indication of tampering or intrusion. Three local homeowners were interviewed and stated they did not hear any siren activation. By all available indications, EWS siren #62 was functional and did not activate on 03/27/13. NRC Site Resident Inspectors have been notified of the retraction." Notified R2DO (McCoy). | ||
| ENS 48342 | 25 September 2012 19:30:00 | 10 CFR 50.72(b)(2)(xi), Notification to Government Agency or News Release | Offsite Notification Due to Tritium in Overflow | At 1215 hours on September 24, 2012, Surry Power Station personnel confirmed the presence of tritium at a level of 1,450 picoCuries/Liter (pCi/L) in a Unit 2 Turbine Building heating steam drain receiver (HSDR) tank. This tank collects condensate from steam which is used to heat buildings. A sample of the condensate was analyzed following failure of the pump (used to control level) which resulted in the tank overflowing to a drain line on September 17 and 23. The sample was taken because the drain line was degraded and the overflow resulted in a release to the environment. The normal inputs into this drain line had been isolated from use in August when the degraded pipe was discovered. Currently, the tank contents are being diverted to a sump until repairs to the drain line and pump are complete. These are expected to complete in the next couple of weeks. Both releases were estimated to be greater than 100 gallons. The location of the leak was within the Protected Area of Surry Power Station. There has been no tritium detected in any monitoring wells in the vicinity of the degraded drain line, nor in any monitoring wells outside the Protected Area. Because the leak remained onsite, no offsite impact to ground water is expected. Furthermore, the leak posed no threat to employees or the public. Because there was a detectable amount of licensed material in the water, Surry implemented communication to offsite agencies as part of (licensee) commitment to the Nuclear Energy Institute (NEI) Ground Water Protection Initiative. This notification is being transmitted due to Notification of Other Government Agencies under 10CFR50.72(b)(2)(xi). The Virginia Department of Environmental Quality, Virginia Department of Health, Virginia Department of Emergency Management, NRC Senior Resident Inspector and Surry County Administrator were notified. | ||
| ENS 48194 | 15 August 2012 19:30:00 | 10 CFR 50.72(b)(2)(xi), Notification to Government Agency or News Release | Offsite Notification Due to Tritium in Degraded Drain Line | At 1000 hours (EDT) on 8/14/12, Surry Power Station personnel confirmed the presence of tritium at a level of 1,250 picoCuries/liter (pCi/l) in the #3 Turbine Building sump. The sump water had been tested upon discovery of a degraded drain line on the sump discharge that resulted in a leak to the environment. The exact volume could not be determined, but it is estimated to be greater than the 100 gallon reporting criteria. The location of the leak is within the Protected Area of Surry Power Station. To prevent additional releases, water from the #3 Turbine Building sump has been redirected to another turbine building sump. There is no Indication that this water has migrated offsite. Because there was a detectable amount of licensed material in the water, Surry has implemented our voluntary communication protocols to the state and Surry County as per our commitment to the Nuclear Energy Institute (NEI) Ground Water Protection Initiative. An adjacent ground water monitoring well was sampled, and no tritium activity was detected in the well water. There has been no tritium detected in any monitoring wells in the vicinity of the drain line, nor in any monitoring wells outside the Protected Area. The activity of the leak was approximately 6% of the criteria for reporting actual ground water activity (20,000 pCi/l). Because the leak remained on site, no offsite impact to ground water is expected. Furthermore, the leak posed no threat to employees or the public. The degraded drain pipe is currently being repaired. This notification Is being transmitted due to Notification of Other Government Agencies under 10CFR50.72(b)(2)(xi). The Virginia Department of Environmental Quality, Virginia Department of Health, and Virginia Department of Emergency Management were notified. The NRC Senior Resident (Inspector) and Surry County Administrator will be notified. | ||

| ENS 44891 | 4 March 2009 19:40:00 | 10 CFR 50.72(b)(2)(xi), Notification to Government Agency or News Release | Relief Valve Failure Results in Tritium and Cesium Spill | At 1100 on March 3rd, 2009 the Main Control Room received a report from the Health Physics Shift Supervisor that 1-BR-RV-114B ( 'B' PG tank heater relief valve) was relieving to the RCA yard near the Primary Grade (PG) tanks. At 1115 an operator confirmed the initial report, stating the relief valve appeared to be full open and relieving at approximately 20 gallons per minute. 0-AP-35.01 (Radioactive Liquid Release Control) was then entered and executed. At 1120 the PG line was then isolated by closing isolation valves, thereby stopping the release. The release amount was then determined per 0-AP-35.01. Using the tank level initial indication of 87.5% taken on operator rounds at 1050 and a final level indication of 87.25%, approximately 450 gallons of water was released. This volume of water coincides with the initial report of an approximate 20 gpm release rate over the 20 minute duration of the event. A sample of the water released was evaluated for tritium and cesium as part of the Nuclear Energy Institute (NEI) Ground Water Protection Initiative. Sample analysis results showed that tritium concentration was 4,810 picoCuries per liter and cesium concentration was 25.1 picoCuries per liter. These concentrations of tritium and cesium pose no threat to employees or the public. Even though the concentrations are well below reportable limits for groundwater, a spill or leak to soil greater than 100 gallons containing licensed material requires that notification be made per VPAP-2103S (Offsite Dose Calculation Manual) as part of our commitment to the NEI Ground Water Protection Initiative. This leak has been contained and relief valve will remain isolated until repaired. This notification is being transmitted due to Notification of Other Government Agencies under 10CFR50.72(b)(2)(xi). The Surry County Administrator was notified. The Senior NRC Resident, Virginia Department of Health, Virginia Department of Emergency Management and Virginia Department of Environmental Quality has or will be notified. | ||
| ENS 42894 | 9 October 2006 15:24:00 | 10 CFR 50.72(b)(2)(xi), Notification to Government Agency or News Release | Potential Violation of Virginia Pollutant Discharge Elimination System Permit | As a result of heavy rains, influent flows to the Surry Sewage Treatment Plant (STP) were in excess of 193,349 gallons on Saturday, October 7. Road conditions prevented normal pumping service from coming onsite to remove this excess water. Resultant analysis showed a loss of 54%, 39% and 10% solids in STP aeration tanks 1, 2 and 3, respectively. These 'solid' parameters are normally an indication that the STP is able to maintain effective treatment. At 1124 on 10/09/06, the Virginia Department of Environmental Quality (DEQ) was notified that the loss of solids may indicate that the treatment capability of the STP is impacted, which may cause a violation of one of the parameters of Surry's Virginia Pollutant Discharge Elimination System (VPDES) Permit. This event is being reported in accordance with 10CFR50.72(b)(2)(xi) due to the fact that the Virginia Department of Environmental Quality was notified at 1124 hours.

| ENS 43740 | 22 October 1976 18:00:00 | 10 CFR 50.72(b)(2)(xi), Notification to Government Agency or News Release | Offsite Notification Due to a Small Leak - Tritium | On October 20, 2007, Surry Power Station workers detected a minor water leak from an underground concrete storm drain pipe inside the station's protected area. This storm drain line flows into the station discharge canal and is monitored by station personnel. Workers had excavated this pipe to conduct inspection activities when they noticed water leaking at a rate of 1 to 2 drips per minute from a pipe joint. The leak rate was estimated at one-half a gallon per day. A sample of the leaking water was evaluated for tritium as part of an industry ground water protection initiative and determined to have a concentration of 31,900 picoCuries per liter. This tritium leak poses no threat to employees or the public. There is no indication that tritium has migrated off the Surry site undetected. Monitoring wells on the perimeter of the Surry site and on-site drinking water well samples have not shown any indication of tritium. Leakage from this section in the storm drain line is ultimately recaptured by the building foundation dewatering system surrounding adjacent site structures and returned to the storm drain line. This leak has been contained and maintenance activities are under way to repair the storm drain line. This notification is being transmitted due to Notification of Other Government Agencies under 10CFR50 72(b)(2)(xi) The Surry County Administrator was notified. The Senior NRC Resident, Virginia Department of Health, Virginia Department of Emergency Management and Virginia Department of Environmental Quality will be notified. |
