Event Notification Report for July 24, 2014

LOST TROXLER MOISTURE/DENSITY GAUGE

While working at a jobsite on the Fort Riley, Kansas federal reservation, the technician had just finished the standard count on a Troxler moisture/density gauge when he received a telephone call to go to another job site for a meeting. The technician placed the gauge back in its case but did not shut the case or lock the case and left it on the tailgate of the truck. When the technician arrived at the second jobsite, an individual approached the technician and told him that he had observed a yellow case fall off the back of the truck near the Camp Forsythe fire station. The technician immediately went back to the fire station. By the time he arrived, fire department personnel had already secured the case with the gauge inside. The technician estimates that the gauge was out of his possession for approximately 8 - 10 minutes. A leak test was performed with no leakage noted and sent to Troxler for further analysis. The gauge will remain out of use until leak results are received from Troxler.

The gauge is a Troxler model 3430 moisture/density gauge containing 9 mCi Cs-137 and 44 mCi Am-241/Be.

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.

AGREEMENT STATE REPORT - MEDICAL UNDERDOSE

The following report was received via e-mail:

"The licensee performed a prostate Iodine-125 (I-125) seed implant on July 24, 2014. The prescribed dose of 144 Gray (Gy) to 90 percent of the prostate gland (D90) was not within 20 percent of prescribed dose [144 Gy prescribed, 86.1 Gy administered]. The post plan performed on August 12, 2014, demonstrated that the prostate D90 was 59.79 percent, not within 20 percent limit of the prescribed dose. The licensee did not notify the Ohio Department of Health of this occurrence as a medical event. The medical event was discovered as a result of an inspection conducted on 10/28/15.

"A Notice of Violation for the medical event and failure to report the medical event has been issued to the licensee. The investigation is ongoing."

Ohio Report: OH150012

A Medical Event may indicate potential problems in a medical facility's use of radioactive materials. It does not necessarily result in harm to the patient.

OFFSITE NOTIFICATION DUE TO INADVERTENT MESSAGE TRANSMITTED VIA EMERGENCY RESPONSE SIREN

"This event is being reported per 10CFR50.72(b)(2)(xi), 'Any event or situation, related to the health and safety of the public or on-site personnel, or protection of the environment, for which a news release is planned or notification to other government agencies has been or will be made.' During troubleshooting activities, a pre-recorded message was inadvertently transmitted from one of eight speakers associated with an emergency response siren. At 1213 CDT, Nemaha County Officials were informed that the message transmission was a spurious actuation. A media/press release is planned."

The licensee notified the NRC Resident Inspector.

OFFSITE NOTIFICATION DUE TO DECEASED AMERICAN CROCODILE
"This 4-hour Non-Emergency notification to the NRC is being made based on a notification to another government agency per 10CFR50.72(b)(2)(xi).

"On July 24, 2014 at 16:04 [EDT], the control room was notified of a deceased American Crocodile inside the intake well. Based on visual evidence of no physical injury or trauma, the crocodile's death was not caused by plant operations. The Federal Fish and Wildlife Service and the Florida Fish and Wildlife Conservation Commission (FWC) were notified."

The licensee notified the NRC Resident Inspector.

TECHNICAL SPECIFICATION REQUIRED SHUTDOWN DUE TO REACTOR COOLANT SYSTEM PRESSURE BOUNDARY LEAKAGE

"At 2315 EDT on July 24th, 2014, CCNPP [Calvert Cliffs Nuclear Power Plant] U1 identified RCS [Reactor Coolant System] pressure boundary leakage from the instrument line to 1-PDT-123A, 11A reactor coolant pump differential pressure transmitter. Technical Specification 3.4.13, Action B was entered and requires that the unit be placed in Mode 3 within 6 hours and Mode 5 within 36 hours. [CCNPP has] initiated plant shutdown in accordance with this Technical Specification. Therefore, this is reportable under 10 CFR 50.72(b)(2)(i) Plant Shutdown Required by Technical Specifications. This is also reportable under 50.72(B)(3)(ii)(A) as a material defect in the primary coolant system that cannot be found acceptable under ASME Section XI, IWB-3600 or ASME Section XI, Table IWB-3410-1."

The licensee notified the NRC Resident Inspector.

* * * UPDATE FROM JAY GAINES TO VINCE KLCO AT 0320 EDT ON 7/25/14 * * *

The licensee reduced reactor power to 10 percent and entered containment. The pressure boundary leak was isolated and the licensee exited the Technical Specification 3.4.13, Action B. The Technical Specification required shutdown was terminated. The licensee is making preparation to increase power to full load.

The licensee will notify the NRC Resident Inspector.

Notified the R1DO (Gray).

RADIATION MONITORING COMPUTER SYSTEM UNAVAILABLE DUE TO PRE-PLANNED MAINTENANCE

"On July 24, 2014 at 0800 EDT, the Unit 2 Radiation Monitoring Computer System will be inoperable and unavailable due to pre-planned maintenance to implement an upgrade to the system. Alternate methods for monitoring are being utilized. The Radiation Monitor Computer System is expected to be restored to available status at approximately 1700 EDT on July 24, 2014.

"This notification is being made in accordance with 10CFR 50.72 (b)(3)(xiii), as an event that results in a major loss of emergency assessment capability, offsite response capability, or offsite communications capability. An update will be provided once the Radiation Monitoring Computer System has been restored to normal operation. The NRC Resident Inspector has been notified."

* * * UPDATED PROVIDED BY TIM KUDO TO JEFF ROTTON AT 1708 EDT ON 7/24/2014 * * *

"The Unit 2 Radiation Monitoring Computer System has been restored to an operable status as of July 24, 2014 at 1650 EDT. The NRC Resident Inspector has been notified."
