| Event Text WASHINGTON AGREEMENT STATE REPORT - EXTERNAL CONTAMINATION ON A TRANSPORT TRAILER
The following information was received from the State of Washington via e-mail:
"Tritium (H-3) contamination was found on a trailer in the outside storage area of Perma-Fix Northwest (PFNW), a radioactive material licensee in Richland Washington on April 17. A DOH inspector noticed liquid dripping from a trailer that had just been unloaded. The trailer had hauled empty radioactive waste drums from Atomic Energy Limited Canada (Chalk River facility in Ontario). The transport vehicle entered the United States at Sault Ste. Marie, Michigan under a Nuclear Regulatory Commission (NRC) import license and entered Washington at Spokane. The shipment had arrived at the PFNW facility in late February. It was manifested as a plastic fiber bag with drums inside. Initial surveys on February 28 noted tritium contamination inside the plastic fiber bag, but no contamination was noted outside the bag or on the trailer. Tritium was a primary radionuclide on the manifest. During off-loading of the drums and plastic liner on April 17, liquid was found in and on the drums (one drum is suspected of being at least partially filled with liquid). After off-loading, standing liquids were noticed by the licensee on the inside trailer bed, but not on the outer trailer floor and skin. After the truck was returned to the storage yard, liquid droplets were found dripping from the front of the trailer by the DOH inspector. Initial contamination levels (up to 1.8 million dpm of tritium) on the trailer front were substantially above the U.S. Dept of Transportation limits; but due to the limited quantity (less than one gallon of liquid), does not pose a health risk. There is no indication of leakage during the actual shipment.
"The manifest indicated the total shipment contained H-3 (6.59 mCi) and Cs-137 (7.79 mCi) as the predominant radionuclides. Only tritium contamination has been noted."
WA Report # WA-08-025
* * * UPDATE FROM MIKEL ELSEN TO KARL DIEDERICH VIA E-MAIL AT 1538 ON 6/11/08 * * *
The trailer was decontaminated and the associated waste will be disposed or processed. The soil under the trailer was removed and packaged for treatment or disposal. The shipper and broker were issued notices of violation. The cause of this incident was poor oversight during packaging.

| Event Text MEDICAL EVENT - EXCESS SKIN EXPOSURE DURING TREATMENT
A women was prescribed a breast cancer treatment using an HDR mammosite balloon brachytherapy. The dose was delivered in 10 fractions using Iridium - 192 seeds. During administration of the first fraction, the physicist received an alarm from the HDR computer, the alarm was overridden based on the judgment of the physicist at the time of the event and the treatment was completed. Additional fraction treatments were also completed as intended.
Subsequent review of the first treatment and the cause of the alarm indicated that a medical event may have occurred. The alarm was indicating that the seed placement was dislodged by 2 centimeters. The physicist thought at the time that the alarm was indicating the seed dislodged by only 2 millimeters. The treatment calculations were revisited and the dislodgment of the seed by 2 centimeters put the seed at the skin entry point of the application catheter. This resulted in an under dose to the target site and an overdose to the skin. Preliminary calculations estimate that the skin in a 7 mm diameter around the catheter entry point may have received a dose of 3700 centigrays based on the strength of the seed (4.47 curies) and the dwell time.
The patient will be notified of the event. The patient's doctor will continue to monitor the skin for any ill effects.
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. |

"The Perry Nuclear Power Plant will be taking the ERDS out of service for scheduled maintenance. From approximately 0200 hours EDT, on June 10, 2008, until 2000 hours EDT, on June 10, 2008, personnel will be performing cleaning and inspection activities on the 120 VAC Emergency Response Information System (ERIS) Computer Power Center. During this planned preventive maintenance, the Integrated Computer System, the Safety Parameter Display System (SPDS), and the automatic mode calculation of the Computer Aided Dose assessment program (CADAP) will incur approximately two periods of unavailability of approximately two hours each. The unavailability periods are necessary to align a temporary power supply and reconnect the 120 VAC ERIS Computer Power Center upon completion of the activities.
"The dose assessment function will be maintained during the brief out of service time periods by manual input of data into CADAP and, if required, by manual calculation. In the event of an emergency, plant parameter data will be orally transmitted to the facilities through the Status Board Ring Down circuit with back-up by the Plant Branch Exchange, the Off Premise Exchange, and various redundant intra-facility circuits throughout the emergency facilities. The ability to open and maintain on 'open line' using the Emergency Notification System will not be affected and will be the primary means of transferring plant data to the NRC as a contingency until the ERDS can be returned to service during the two periods of unavailability. This event is being reported in accordance with 10 CFR 50.72(b)(3)(xiii), as a condition that results in a major loss of offsite communications capability. A follow-up notification will be made when the activities are completed and the equipment is restored. The Resident Inspector has been notified."
* * * UPDATE FROM DAVE O'DONNELL TO JOE O'HARA AT 1514 ON 6/10/08 * * *

"This report is being made pursuant to 10CFR50.72(b)(3)(v)(D), Event or condition that could have prevented fulfillment of a safety function needed to mitigate the consequences of an accident. During steady state operations, a Division 3 AC ground alarm was received, followed by a trip of the 2VD05C Division 3 switchgear room / Core Standby Cooling System (CSCS) Pump Room Supply Fan. Division 3 supplies power to the High Pressure [Core Spray] (HPCS), which is a single-train system. Although the system remained functional and capable of vessel injection following the failure, the HPCS system and its associated power supplies were declared inoperable based on long-term temperature considerations. At 1703, the circuit breaker for the HPCS injection valve, which is a Primary Containment Isolation Valve (PCIV), was opened and the valve deenergized in the closed position to comply with Technical Specifications. Disabling the injection valve affects the safety function of the system (HPCS), and this is reportable as an 8-hour ENS notification.
"The cause of the ventilation fan motor trip has been determined to be a motor fault. Replacement of the fan motor is in progress."
This event places the plant in a 14-day LCO per Technical Specification 3.5.1. Repairs are expected to be completed by 0700 on 6/12/08. The Reactor Core Isolation Cooling (RCIC) system is operable.

"On June 11, 2008 at 14:05 PDT licensed plant operators entered Technical Specification (TS) 3.0.3 on Units 1 and 2 due to identification of a potential ASCO solenoid valve failure that could initiate draining if the safety injection system accumulators following a small break Loss-of-Coolant-Accident (LOCA).
"ASCO Model 8316 and 8321 pilot operated solenoid valves over 12 years old are susceptible to a potential shuttle ("insert" per vendor documentation) malfunction. The malfunction is that with greater than 12 years of service and a loss of minimum operating pressure differential (MPOD), the shuttle (or insert) could reposition and fail to return to the desired position. This MPOD related reposition could result following instrument air pressure loss and subsequent restoration to containment following a postulated small break LOCA. Diablo Canyon Power Plant (DCPP) Units 1 and 2 each have four susceptible ASCO solenoid valve locations used as drain valves for each of the four safety injection system accumulators per unit.
"DCPP is reviewing the performance of the ASCO solenoids based on a plant problem report and subsequent discussion with the vendor. The safety significance of this event is low as there was no actual accumulator drain valve failure. Although PG&E is still evaluating the potential degradation mechanism and failure mode of these valves, TS 3.03 was conservatively entered base on the potential for malfunction of these valves.
"On June 11, 2008, at 16:10 PDT licensed plant operators exited TS 3.0.3 following isolation of the suspect accumulator drain lines. A licensee event report will be issued for this event.
"The NRC Resident Inspector has been notified." |
