The activity contained in the radiographic exposure device at the time of the incident was 2.66 terabecquerels (72 Ci). A crimped fitting on the crank cable housing came loose when a radiographer was moving the radiographic exposure device. The source was in the shielded position at all times when it was being moved. No source disconnect occurred. The cause of this incident is not known since the equipment had been functioning until this incident. The licensee believes it to be a manufacturing problem. When the incident occurred, radiographic operations were immediately stopped. And the radiography crew (radiographer, radiographer's assistant, and Radiation Safety Officer) returned to the licensee's Utah facilities. The control cable was tagged out of operation until a new housing could be obtained from the manufacturer. "The Utah Division of Radiation Control was notified by the licensee in a letter dated March 23, 2006 (received on March 29, 2006). "The licensee notified the manufacturer and the malfunctioning equipment was returned. It was immediately replaced with a new cable housing.

This activity was being performed on Work Order 2042825001. At the approximate time the recorder was being removed from service the shift received a RPS trip from a MTCV [Main Turbine Control Valve] Fast Closure. The control valve fast closure scram was caused by a power load imbalance. Both RFP's [Reactor Feed Pumps] tripped on high reactor water level and RCIC and HPCI were used (for 7 and 2 minutes respectively) to control RWL [Reactor Water Level]. Eight SRV's [Safety Relief Valves] opened momentarily on high reactor pressure. The highest reactor pressure indicated was 1120 psig and the lowest RWL indicated was +7 inches. A main condenser vacuum transient due to loss of seals required use of HPCI and RCIC." The licensee characterized the scram as uncomplicated. All systems functioned as required and nothing unusual or not understood besides what caused the initial power load unbalance signal and resulting MTCV fast closure. All rods fully inserted. The unit is currently at normal pressure and water level for Mode 3. MSIVs remained opened and decay heat is being discharged to the main condenser. The scram had no impact on Unit 1. Offsite on onsite electrical conditions remained normal. The licensee was not in any significant LCO at the time of the event. The licensee notified the NRC Resident Inspector. | Power Reactor | Event Number: 42472 | Facility: BRAIDWOOD Region: 3 State: IL Unit: [1] [2] [ ] RX Type: [1] W-4-LP,[2] W-4-LP NRC Notified By: GREG BAKER HQ OPS Officer: JOE O'HARA | Notification Date: 04/05/2006 Notification Time: 11:45 [ET] Event Date: 04/05/2006 Event Time: 06:35 [CDT] Last Update Date: 04/05/2006 | Emergency Class: NON EMERGENCY 10 CFR Section: 26.73 - FITNESS FOR DUTY | Person (Organization): ANNE MARIE STONE (R3) | Unit | SCRAM Code | RX CRIT | Initial PWR | Initial RX Mode | Current PWR | Current RX Mode | 1 | N | Y | 100 | Power Operation | 100 | Power Operation | 2 | N | Y | 100 | Power Operation | 100 | Power Operation | Event Text FITNESS FOR DUTY - CONFIRMED POSITIVE FOR NON-LICENSED CONTRACTOR SUPERVISOR A non-licensed contract supervisor had a confirmed positive for alcohol while attempting to gain access the plant this morning.

The plates had a triangular shaped tip on the end that measured about 1 inch at the base, 1 inch high and was 0.1 inch thick. On one of the fuel plates, the tip broke off and the Department's RSO maintained the piece in an envelope in the same locked container where he kept the fuel plates. In 1977 during the course of routine laboratory nuclear training work with the fuel plates, one of the students wanted to look at the structure of the piece microscopically for a course in Metallurgy. The RSO gave the student the tip in an envelope sandwiched between 2 copper sheets. The student returned the piece in the envelope, and the envelope was returned to the safe unopened. On March 16, 2006, the envelope was opened to obtain data on the piece for return to Federal control, and the piece was not in the envelope. Further investigation determined that the tip was too large to be used in the Scanning Electron Microscope (SEM), and a small piece of the tip was removed. It appears that only this small piece was returned to the RSO. Personnel from the Metallurgy laboratory were questioned and it appears that the tip remained in the Metallurgy facility until after 1991 when it is thought that it was disposed of in the regular trash. The uranium fuel plates were 20 weight percent enriched Uranium. The tip contained approximately 1.1 grams enriched uranium or 0.21 gm U-235. It had an activity of 0.3 micro curies U-238 and 0.4 micro curies U-235. On contact measurements for the tip are expected to be less than 1 milli rem per hour on contact. On March 30, 2006, the Director, Occupational Health and Safety conducted a thorough search and survey of the Metallurgy laboratory and could not find the tip. 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. | Hospital | Event Number: 42474 | Rep Org: COMMUNITY HOSPITALS OF INDIANA Licensee: COMMUNITY HOSPITALS OF INDIANA Region: 3 City: INDIANAPOLIS State: IN County: MARION License #: 130600901 Agreement: N Docket: NRC Notified By: ANDREA BROWNE HQ OPS Officer: JOE O'HARA | Notification Date: 04/05/2006 Notification Time: 13:31 [ET] Event Date: 11/08/2005 Event Time: [CST] Last Update Date: 04/05/2006 | Emergency Class: NON EMERGENCY 10 CFR Section: 35.3045(a)(3) - DOSE TO OTHER SITE > SPECIFIED LIMITS | Person (Organization): ANNE MARIE STONE (R3) GREG MORELL (NMSS) | Event Text NOTIFICATION OF A MEDICAL EVENT - DOSE TO INCORRECT AREA OF BODY Community Hospitals of Indiana reported that a high dose rate (HDR) remote afterloader treatment field was incorrectly performed. On November 8, 2005, Community Hospital East in Indianapolis, Indiana performed a HDR treatment on a terminally ill lung cancer patient. Community Hospital East applied the correct dose to the patient. However, a catheter used to carry the source into the patients body was inserted into the patients airway without a cap on the end. As a result of the cap not being in its proper place on the catheter, the source was placed approximately 7 mm higher than originally intended per the physicians written directive. As a result, the field which was irradiated was greater by approximately 7 mm. Immediately following the treatment, the error was noted and the physician was informed. The physician noted that the area which was irradiated was within her area of concern and that everything was "o.k." This treatment was conducted to relieve patient symptoms rather than cure the disease. The patient succumbed to the disease approximately two weeks later. The treatment and its results were documented by the licensee in its Radiation Safety Committee Meeting minutes. During a routine inspection of its records on 4/4/06, a Region III NRC Inspector noted that this event appeared to be a medical event and should be reported. As a result of that guidance, the licensee is reporting the event. | Power Reactor | Event Number: 42475 | Facility: THREE MILE ISLAND Region: 1 State: PA Unit: [1] [ ] [ ] RX Type: [1] B&W-L-LP,[2] B&W-L-LP NRC Notified By: KEVIN COUGHLIN HQ OPS Officer: STEVE SANDIN | Notification Date: 04/05/2006 Notification Time: 14:08 [ET] Event Date: 04/05/2006 Event Time: 08:04 [EDT] Last Update Date: 04/05/2006 | Emergency Class: NON EMERGENCY 10 CFR Section: 50.72(b)(3)(v)(D) - ACCIDENT MITIGATION | Person (Organization): PAT FINNEY (R1) | Unit | SCRAM Code | RX CRIT | Initial PWR | Initial RX Mode | Current PWR | Current RX Mode | 1 | N | Y | 100 | Power Operation | 100 | Power Operation | Event Text BOTH TRAINS OF HIGH PRESSURE INJECTION (HPI) DECLARED INOPERABLE DUE TO POTENTIAL AIR BINDING OF PUMPS "TMI declared both High Pressure Injection Trains not operable due to air void in the suction line from the Sodium Hydroxide tank. The postulated issued is that in the event of a small break LOCA where the plant would need to go on HPI piggy back Ops (the Low Pressure Injection supplying suction to the High Pressure Injection pumps) the air could cause the HPI pumps to become air bound. "The Plant entered a shutdown Tech Spec 3.0.1 at 0804 [EDT] and exited the timeclock at 0850 [EDT] when the Sodium Hydroxide tank was isolated, thus isolating the air void from the ECCS (Emergency Core Cooling System) pumps." The licensee is continuing their investigation into root cause and operability. The licensee will inform the NRC Resident Inspector. | Power Reactor | Event Number: 42476 | Facility: PERRY Region: 3 State: OH Unit: [1] [ ] [ ] RX Type: [1] GE-6 NRC Notified By: KENNETH MEADE HQ OPS Officer: JOE O'HARA | Notification Date: 04/05/2006 Notification Time: 15:05 [ET] Event Date: 04/05/2006 Event Time: 12:00 [EDT] Last Update Date: 04/05/2006 | Emergency Class: NON EMERGENCY 10 CFR Section: 50.72(b)(2)(xi) - OFFSITE NOTIFICATION | Person (Organization): ANNE MARIE STONE (R3) | Unit | SCRAM Code | RX CRIT | Initial PWR | Initial RX Mode | Current PWR | Current RX Mode | 1 | N | Y | 100 | Power Operation | 100 | Power Operation | Event Text OFFSITE NOTIFICATION TO STATE AND LOCAL OFFICIALS CONCERNING TRITIUM DETECTION IN DRAIN SYSTEM "This notification is being made in accordance with 10CFR50.72(b)(2)(xi), i.e., notification of a government agency.

The inoperability is due to a logic failure that would prevent the automatic opening of MO-3-23-015, 'HIGH TURBINE STEAM LINE INBOARD ISOLATION VAVLE'. MO-3-23-015 is a normally open valve located inside Primary Containment. The HPCI system initiates upon receipt of a reactor low water level (level 3) signal or a high drywell pressure signal. Upon a HPCI system initiation MO-3-23-015 is required to automatically open, if closed, with no isolation signal present. The automatic opening of MO-3-23-015 is required to ensure the design function of HPCI is fulfilled. The design function of HPCI is to assure that the reactor is adequately cooled to limit fuel-clad temperature in the event of a small break in the nuclear system and loss of coolant, which does not result in rapid depressurization of the reactor vessel. HPCI permits the nuclear plant to be shut down while maintaining sufficient reactor vessel water inventory until the reactor vessel is depressurized. "The HPCI system inoperability has no immediate impact on plant operations. The inoperability places Unit 3 in a 14-day shutdown Tech Spec Action Statement. The 14-day shutdown Tech Spec action statement commenced on 04/05/06 @ 0824 when the Logic System Function Test was started. "A troubleshooting and repair team has been initiated to determine a cause and repair of the deficiency." The NRC Resident Inspector was notified of this event by the licensee. | Power Reactor | Event Number: 42479 | Facility: DUANE ARNOLD Region: 3 State: IA Unit: [1] [ ] [ ] RX Type: [1] GE-4 NRC Notified By: W.
