WISCONSIN AGREEMENT STATE REPORT - NDC GAUGE FOUND IN SCRAP YARD


The following Agreement State report from Wisconsin was received via Facsimile:

"License No.: Non-licensee

"Licensee: Non-licensee

"Event Location: Gorden Schneider Property

"Event Type: Scrap Yard Detector

"Notifications: Phone call from Sadoff yard on 9/28/07.


"DHFS was contacted on 9/28/07 concerning a rejected load from Sadoff scrap yard in Fond du Lac. The yard made the initial contact and had the individual with the load talk to DHFS before leaving the yard. A hand monitor (survey) gave radiation reading of 200 microR/hr on the outside of the trailer. A metal tank was observed where the reading was noted. He was told to off load and cover it with plastic until DHFS responds. The individual with the rejected load contacted DHFS on 10/01/07 requesting what to do about the load. Evidently, the individual had made a second attempt to sell the material to Sadoff. When contacted, he reported there were CRM labels on the device. It was reported to be about a foot long, with 8 prongs and 3 fins. A label stated that it was sold under Gen. Lic. No. CL 1933-70. The label for NDC listed Duarte, CA, 91010. The individual was requested to not handle the device and to place it in a secure location.

"No information on this device was in the DHFS GL database. DHFS contacted NDC and was informed that it was a Model 103 with 150 mCi of AM-241. The gauge had been sold to Sabee Co, 1718 West Eighth St, Appleton, WI on 12/12/85. The last contact that NDC had with the gauge was 11/20/95. A call was made to Sabee Co in Appleton. An individual there reported that the company was divided in 2002 and management changed in 2003. The company used to do film extrusion. The individual promised to follow up with someone who had been there for a long time and might remember more about the film extrusion process. Contact nos. were given to two former owners. DHFS plans to investigate on October 3, 2007."

Media attention: None


Event Report ID No.: WI070026.

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.

MEDICAL EVENT INVOLVING HIGHER THAN PRESCRIBED DOSE

On August 31, 2006 a female patient received mammosite treatment for a breast lesion using a HDR with an Ir-192 source. The treatment consisted of placing a catheter into the treatment site, inflating a balloon with between 35-75 ml saline and positioning the Ir-192 source inside the catheter into the center volume of the saline balloon. This allows for a homogenous dose to the treatment site. While in the OR (Operating Room), the catheter was inserted and saline introduced through one of the two catheter connections to inflate the balloon. The patient was taken to the HDR location where the technologist inadvertently connected the HDR to the saline vice the HDR connector. This resulted in draining the saline balloon into the HDR unit. The technologist recognized that the HDR was improperly connected, broke the connection and reconnected to the proper port. When the prescribed 416 second treatment was commenced, the HDR automatically shutdown after 223 seconds retracting the Ir-192 source to the safe position. An evaulation by the licensee concluded that the incident was not reportable since it did not meet the criteria for an underdose.

During an inspection conducted 7/26/07 (Inspection Report No. 2007-001), the NRC Inspector noted that since the saline balloon had been inadvertently drained tissue in a .5 cubic centimeter volume adjacent to the source received a significantly higher dose (approximately 20 Gray) than prescribed. In a followup call from NRC Region I on 10/03/07, the licensee was requested to notify the NRC Operations Center of this finding.

The licensee informed the prescribing physician and the patient was also notified. No adverse effects to the patient have been noted.

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.

AGREEMENT STATE REPORT - LEAKING SEALED SOURCE

"Keymaster's Radiation Safety Officer reported they had recently (in September 2004) received a batch of eleven Cobalt 57, foil sources, Model PHI-0106, from Isotope Products Laboratory. One of the eleven sources failed its receipt leak test. The others were tested and were not leaking.

The State of Washington provided the following information via e-mail:

"The contaminated foil source had Serial Number B9-774 and had an activity of 437 megabecquerels (11.8 millicuries). When wiped, the level of contamination was about 500 counts per minute above background. The source may have been leaking or could have had residual contamination; this was never determined. The source was returned to the supplier.

"The work areas and personnel were surveyed and found uncontaminated.

"No media attention at present.

"Subsequent inspections by DOH performed 10/31/2005 and 9/21/2006 found no contamination and no additional reoccurrences of receiving contaminated sources.

"Notification Reporting Criteria: WAC 246-221-250

"Isotope and Activity involved: Cobalt 57, 437 mBq (11.8 mCi).

There were no overexposures. The leaking source was an Isotope Products Laboratories XRF source Model PHI-0106, S/N B7-461. The leaking source was wiped down to 416 counts, placed back into its shield. It was returned to supplier.

There was minor contamination in the source storage area. The licensee has since cleaned the area. Wipe surveys performed by the licensee and DOH showed no contamination.

LOSS OF BOTH EMERGENCY SERVICE WATER PUMPS

"On October 5, 2007, at approximately 0408, while attempting to open 480 VAC breaker 1B4234A/B for preplanned maintenance, a loss of bus 1B42 occurred. The preliminary cause of the bus trip was arcing of the bucket stabs/bus bars when opening the door to breaker 1B4234A/B. The arcing was a result of the breaker bucket inadvertently pulling away from the bus. At the time of this event, the 'A' Emergency Service Water (ESW) pump was out of service for preplanned maintenance. The loss of 1B42 resulted in a loss of the 'B' ESW pump. The 'A' ESW pump was subsequently returned to service at 0458 on October 5, 2007. Note that power was conservatively lowered approximately 4% at 0512. At the time of this power reduction, the plant was not in a Technical Specification that would require a plant shutdown.

"In addition to the loss of the 'B' ESW pump, the loss of 1B42 resulted in invalid Group 1-5 isolations on the 'B' side of PCIS (not including Main Steam Line Isolation Valves).

"This event is reportable under 10 CFR 50.72(b)(3)(v), Any event or condition that alone at the time of discovery could have prevented the fulfillment of the safety function of structures or systems that are needed to (D) Mitigate the consequences of an accident.

"The licensee notified the NRC Resident Inspector."

The licensee has not yet determined if this is a mechanical failure of the breaker or a human error. However, they are looking at OE associated with this issue.

PROCESS GAS LEAK DETECTION (PGLD) SYSTEM INOPERABLE

"At 1643 CDST, on 10-05-07 the Plant Shift Superintendent (PSS) was notified that an alarm was received for the C-333 Unit 6 Cell 8 UF6 [Process Gas Leak] Detection (PGLD) System. Operators responded and found that the READY and MANUAL lights for this system were not illuminated. This PGLD System contains detectors that cover C-333 Unit 6 Cell 8 and Section 4 of the cell bypass piping. At the time of this alarm, unit 6 cell 8 and some areas of Section 4 of the cell bypass were operating above atmospheric pressure."

Electricians are currently troubleshooting to determine the source of the potential short circuit that caused the problem.

"[Technical Safety Requirement] (TSR) 2.4.4.1 requires that at least the minimum number of detector heads in the cell and in each defined section of the cell bypass are operable during steady state operations above atmospheric pressure. With the Unit 6 Cell 8 PGLD system inoperable, none of the required cell heads and only 2 of the required 3 heads in Section 4 of the cell bypass were operable. This PGLD System was declared inoperable, TSR LCO 2.4.4.1.C.1 was entered and a continuous smoke watch was put in place within one hour.

"Engineering has determined that the system would not have been able to perform its intended safety function when this alarm came in. This event is reportable as a 24 hour event in accordance with 10 CFR 76.120(c)(2)(i). This is an event in which equipment is disabled or fails to function as designed when:

"a. The equipment is required by a TSR to prevent releases, prevent exposures to radiation and radioactive materials exceeding specified limits, mitigate the consequences of an accident, or restore this facility to a pre-established safe condition after an accident;

"b. the equipment is required by a TSR to be available and operable and either should have been operating or should have operated on demand; and

"c. no redundant equipment is available and operable to perform the required safety function.

"The NRC Resident Inspector has been notified of this event. PGDP Assessment and Tracking Report No. ATR-07-2655; PGDP Event Report No. PAD-2007-15; Responsible Division: Operations."

MANUAL REACTOR TRIP DUE TO CONDENSER TUBE RUPTURE

"The following event description is based on information currently available. If through subsequent reviews of this event, additional information is identified that is pertinent to this event or alters the information being provided at this time, a follow-up notification will be made via the ENS or under the reporting requirements of 10CFR50.73.

"On October 6, 2007, at approximately 10:59 Mountain Standard Time (MST) Palo Verde Unit 2 plant operators manually tripped the reactor from approximately 100% rated thermal power. The reactor was tripped when sodium levels in both steam generators reached trip criteria following a condenser tube rupture. Unit 2 was at normal temperature and pressure prior to the trip. All CEAs inserted fully into the reactor core. This was an uncomplicated reactor trip.

"No ESF actuations occurred and none were required. Safety related buses remained energized during and following the reactor trip. The offsite power grid is stable. No significant LCOs have been entered as a result of this event. There was no loss of normal heat removal capabilities, or loss of any safety functions associated with this event. No major equipment was inoperable prior to the event that contributed to the event. "

No PORVs or MSSVs lifted. Decay heat is being removed with Auxiliary Feedwater feeding the steam generators steaming to the condenser. There are no primary to secondary tube leaks in the steam generators. Emergency buses are powered by offsite power with Emergency Diesel Generators in standby.

"The event did not result in any challenges to fission product barriers and there were no adverse safety consequences as a result of this event. The event did not adversely affect the safe operation of the plant or the health and safety of the public.

"The [NRC] Resident Inspector was informed of the Unit 2 reactor trip and this notification."

PRIMARY CONTAINMENT LEAK RATE EXCEEDED

"At 0114 EDT on 10/7/07, Fermi 2 feed water line check valves, B2100-F010B and B2100-F076B, failed their local leak rate tests. The leakage rate of the inboard check valve (B2100-F010B) was 297.3 SCFH and the leakage rate of the outboard check valve (B2100-F076B) was indeterminate due to leakage exceeding the capability of the leak rate monitor. Thus, the minimum path leakage through penetration X-9B is 297.3 SCFH. This leak rate exceeds the Primary Containment allowable leakage rate (1.0 La) of 296.3 SCFH per Tech. Spec. 5.5.12. The NRC Resident Inspector has been notified of this event."

The licensee is reporting a degraded safety function associated with the primary containment barrier. The licensee intends to repair the leaking valve and retest it prior to any mode change. There is no LCO associated with this condition because the licensee is in mode 5.

POTENTIAL PERSONNEL OVEREXPOSURE

A representative of Landauer (the optically stimulated dosimeter provider) reported to the hospital that a person on the hospital staff received a 113,165 millirem deep dose whole body reading for the reporting period of 8/1/07 - 8/31/07. The shallow dose reading was 107,506 millirem. The Radiation Safety Officer (RSO) contacted the individual with the high dose reading. The individual said that he had no ill health effects so he believed the reading was not correct. The individual said that he normally wears his dosimeter attached to a lanyard that he wears around his neck. He did remember one day when a therapist brought him his dosimeter from a linear accelerator room. The individual did not recall leaving his dosimeter in the room.

The RSO talked to a representative of Landauer about distinguishing between a potential dose from an accelerator and other doses the individual may have received from performing his duties but this could not be definitively done.
