| Unit | SCRAM Code | RX CRIT | Initial PWR | Initial RX Mode | Current PWR | Current RX Mode | | 1 | N | N | 0 | Hot Standby | 0 | Hot Standby | Event Text NOTIFICATION OF UNUSUAL EVENT DUE TO UNIDENTIFIED RCS LEAKAGE GREATER THAN 10 GPM
While in Mode 3, South Texas Project Unit 1 declared an Unusual Event at 0639 CST on 11/13/15, due to SU7 of EAL1- Unidentified RCS or Pressure Boundary leakage greater than 10 gpm.
The excessive leakage to the WHT (waste holding tank) occurred when a letdown system demineralizer was placed in service. Operators bypassed the demineralizer and the RCS leakage was stopped. The excess leakage lasted for approximately 8 minutes and the maximum leakage was estimated to be 12-15 gpm.
There was no impact on South Texas Unit 2 which continues to operate at 100% power.
South Texas Project Unit 1 exited the Unusual Event at 0802 CST on 11/13/15, after verifying Unidentified RCS leakage less than 1 gpm. The demineralizer drain valve was partially open and was the cause of the excess leakage. The drain valve has been closed.
The licensee has notified the NRC Resident Inspectors.

* * * UPDATE AT 1414 EST ON 11/13/2015 FROM JASON BERRIO TO MARK ABRAMOVITZ * * *
"Due to entering the STP [South Texas Project] Emergency Plan (Unusual Event), STP has officially determined to make a planned press release. Per 10 CFR 50.72(b)(2)(xi), STP is making a notification to the NRC via the emergency notification system (ENS).
"The NRC Resident Inspector has been notified of the press release.
"The planned press release shares the following information:
"On November 13, 2015, STP Nuclear Operating Station, Unit 1, declared an Unusual Event at 0639 CST. Plant operators identified increasing reactor coolant system leakage in Unit 1. Plant Operators took immediate actions to verify the source and safely isolate and stop the leakage. Upon identifying the source of the leakage, the Unusual Event was exited at 0802 CST on November 13, 2015.
"The leakage was captured and maintained within an on-site storage tank and there was no radioactive release to the environment. STP Unit 1 is preparing for restart following a scheduled refueling and maintenance outage."
Notified the R4DO (Gaddy).
* * * RETRACTION AT 1221 EST ON 12/08/15 FROM MARC HILL TO JEFF HERRERA * * *
"The purpose of this report is to retract the ENS report made in accordance with 10 CFR 50.72 (a)(1)(i) on November 13, 2015, at 08:21 EST (ENS # 51536). STP Nuclear Operating Company declared an Unusual Event at 0639 CDT on November 13, 2015, based on Initiating Condition for Reactor Coolant System (RCS) Leakage Emergency Action Level (EAL) SU7. The event was reported to the NRC under EN # 51536 and the event was subsequently terminated on November 13, 2015 at 0802 CST. After further review, the emergency declaration is being retracted because the source of the leakage was from the Chemical and Volume Control System (CVCS) and not from the RCS."
The NRC Resident Inspector will be notified.

The following information was received from the State of Colorado via email:
"Event Date and Time: 11/17/15. Time is unknown as the current owner took possession of the property after a business had remodeled the interior of the structure. This report is for an exit sign that was disposed of between 2007 to 2012.
"Event Type: Lost Exit Sign
"Event Description: An exit sign was purchased during the renovation of a church to an office. By Design Homes purchased the property in 2007 and used the property for their offices until the renovation was completed and resold as private residence in 2012. The disposition of the exit [sign] is unknown. By Design Homes was unaware of the exit sign containing Tritium.
"Detail: During an audit of the records, a contact was made with one of the investors who worked with By Design Homes. During the discussion, we [Colorado Department of Public Health and Environment (CDPHE)] discovered the transition [of] the property from a church to By Design Homes. They renovated the property [into] a private residence. It is unknown what happened with the exit sign. Speculation is the sign was taken down and disposed of in a dumpster during the renovation from the business to a residence.
"The current owner does not have any record of an exit sign being in the home when purchased in 2012.
"Our [CDPHE] office made contact with By Design Homes, leaving emails with the investor to relay the incident and to obtain a corrective action report. No further communication has been received at this date."

Sources that are "Less than IAEA Category 3 sources," are either sources that are very unlikely to cause permanent injury to individuals or contain a very small amount of radioactive material that would not cause any permanent injury. Some of these sources, such as moisture density gauges or thickness gauges that are Category 4, the amount of unshielded radioactive material, if not safely managed or securely protected, could possibly - although it is unlikely - temporarily injure someone who handled it or were otherwise in contact with it, or who were close to it for a period of many weeks.

| Event Text CRANE ITEM RELIED UPON FOR SAFETY NEVER INSTALLED
"During unrelated maintenance, it was discovered that the UUSA UBC crane was missing components that are within the IROFS27e, QL1 boundary. These components have been missing since the crane went into operation in early 2015. The IROFS [Item relied upon for safety] has been declared degraded and is currently inoperable, and in a location where it cannot impact licensed material.
"This IROFS is designed to mitigate the consequences of UF6 release, to meet 10 CFR 70.61 performance requirements. No accident occurred, no release occurred.
"During the period in which the crane was operating in a degraded state, no design basis accidents occurred, thus there are no actual consequences. The crane had been moved to a safe position in order to perform other repairs (away from licensed material), and it locked in a place, thereby removing applicability of the IROFS. Thus, there is currently no potential for consequences.
"During unrelated repair activities, it was discovered that the URENCO USA UBC Crane has been in operations since March of 2015 while in a degraded condition. A component within the IROFS QL1 boundary was never installed.
"This is a sole IROFS to mitigate consequences. There are no other IROFS in place to support this function. Currently there is no analysis available to support the ability of the degraded IROFS to perform its safety function.
"There were no design basis external events during operation of the crane, nor do any currently exist.
"The UBC Crane was already locked out for ongoing corrective maintenance, The lockout remains active, and the IROFS is now declared inoperable. The condition was entered into the USA's Correcting Action Program for Evaluation and Corrective Actions.
"The degraded IROFS has been declared inoperable. No accident sequences occurred.
"The plant did not enter an emergency classification, nor is one planned.
"There are no planned notifications other that this event notification to the NRC Operations Center."
The NRC Regional Inspector (Munson) was notified. | |
