Event Text

AGREEMENT STATE REPORT - STOLEN MOISTURE DENSITY GAUGES

"[The State of Florida] received a report from the company's RSO at 0945 that three soil moisture density gauges and cases were stolen. [A] Conex box at [the] site was locked and broken into. All three gauges were chained and locked to [the] interior of [the] Conex box. All three locks were broken. [The] cases were locked with the gauges inside when stored. [The] owner still has keys to the cases and gauges. [The] licensee will offer a reward. Local police have been notified and [the] licensee is currently awaiting their arrival."

All three stolen gauges were Troxler Model 3430, Serial Numbers 31318, 25778, and 19575. Each gauge contained a 40 mCi AmBe source and a 8 mCi Cs-137 source.

FL:10-067

THIS MATERIAL EVENT CONTAINS A "LESS THAN CAT 3" LEVEL OF RADIOACTIVE MATERIAL

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.

BOTH TRAINS OF RESIDUAL HEAT REMOVAL (RHR) INOPERABLE

"On 5/19/2010 at 1209 CDT, Unit 2 entered Mode 4 from Mode 5 and started realigning RHR from a shutdown cooling to an Emergency Core Cooling System (ECCS) lineup. During this transition, the suction check valves for the RHR pump are tested for safety function closed per the In-service testing program . The valves are closed to provide train separation for the RHR trains and to prevent diversion of flow from suction sources.

"On 5/19/2010 at 1228 CDT, both Unit 2 trains of RHR were declared inoperable due to the failure of the pump suction line check valve for each RHR pump (2RH-3-1 and 2RH-3-2) to meet In-Service Testing (IST) acceptance criteria. Technical Specification 3.5.2 Condition A was entered for inoperability of the one required ECCS train (RHR) in Mode 4 with Reactor Coolant System (RCS) cold leg temperatures above safety injection pump disable temperature.

"On 5/19/2010 at 1640 CDT, both RHR pit sump covers were opened to facilitate multiple entries into each sump while performing a revised test procedure to verify the operability of check valves 2RH-3-1 and 2RH-3-2. The pit sump covers are required to be closed in [Modes 1 through 4] for each operable RHR train. Since both trains of RHR were inoperable both covers were opened.

"On 5/19/2010 at 1947 CDT the pit sump cover was closed for one train of RHR.

"On 5/19/2010 at 2005 CDT the revised test procedure was approved and completed satisfactorily. The train of RHR with the pit sump cover closed was declared operable and Technical Specification 3.5.3 Condition A was exited. Both suction check valves passed the closed safety function and a loss of safety function did not occur as originally thought on 5/19/2010 at 1228 CDT.

"On 5/19/2010 from 1640 CDT to 1947 CDT both trains of RHR were inoperable due to both pit sump covers open on both RHR trains. The inoperability of both trains of RHR represents a condition that prevented the fulfillment of the safety function of structure or systems that are needed to remove residual heat and mitigate the consequences of an accident."

The licensee has notified the NRC Resident Inspector.

OFFSITE NOTIFICATION - BETHEL FIRE DEPARTMENT RESPONDED TO GRASS FIRE NEXT TO PLANT

"Notification [was made] to make the NRC aware of a call to Bethel Fire Department for assistance in extinguishing a grass fire on Catawba property. The fire was caused by an arc flash, resulting from a large bird coming in contact with a York cooperative power line. [The] fire is extinguished. Fire was outside the owner controlled area. [The area burned] is approximately 100' x 100'. [There was] no property damage [to the site]."

Both units were unaffected by this event and maintained 100% reactor power. The fire was located in a brush field located in Catawba Park and took approximately 30 minutes to distinguish.

The licensee notified the NRC Resident Inspector. The licensee also notified Mecklenburg, Gaston, and York counties as well as the state of North Carolina and South Carolina.

OFFSITE NOTIFICATION DUE TO TRANSPORTATION ACCIDENT

"This is a Non-Emergency 4 hour notification being made in accordance with 10 CFR 50.72(b)(2)(xi), an Offsite Notification. On May 20, 2010, at approximately 1535 CDT Waterford 3 was notified by the Louisiana (LA) State Police that a transportation accident occurred involving a low level radioactive shipping container that was being carried by a tractor trailer truck located at mile marker 22 East on interstate highway I-12 near Walker, LA in Livingston Parish. The surface contaminated object (SCO) metal shipment container was being used by Miller Transfer Houston to transport a used Reactor Coolant Pump (RCP) motor from Waterford 3 nuclear plant in Killona, LA to Westinghouse Waltz Mill in Madison, PA. The shipment weighing approximately 145,000 pounds departed Waterford 3 at approximately 1230 CDT with identification number of 10-3044 and pre-shipment radiological survey information of contamination levels of less than or equal to 15,000 dpm/100cm2 and dose rates of less than or equal to 0.4 mR/Hr. The tractor trailer is on its side, just off the interstate, on the grass. The shipping container boxed cover lid has opened, exposing the RCP motor, showing that it is still wrapped with contamination protective covering and still fastened to the container base and trailer. The initial, basic radiological assessment performed by the LA State Police Hazmat technician supervisor resulted in no indication of hazardous levels of radiation dose rates. Waterford 3 dispatched a Radiation Protection field team who arrived at approximately 1840 CDT and surveyed the container and the contents. The survey results indicate no radiological breach, with smear results of contaminations no higher than background and radiation dose rates of no higher than 0.5 mR/Hr.

"There was no report of other vehicles involved. The driver was contacted by cell phone, who reported that he has been transported to the hospital emergency room for a CAT scan. The failure mode has yet to be determined."

The licensee has notified the NRC Resident Inspector.
