The licensee provided the following information via facsimile (licensee text in quotes):
"On Friday, April 8, 2005 at approximately 8:30 a.m., the Wisconsin Radiation Protection Section (RPS) received notification from the University of Wisconsin, Madison, WI (license number 25-1323-01) of a potential medical event involving a therapeutic radiation dose from a Yittrium-90 Zevelin treatment in which the delivered dose may have differed from the prescribed dose by more than 0.5 Sv (50 rem) and by 20% or more of the prescribed dose. [HFS 157.72 (1) (a) 1.]
"On Tuesday, April 5, 2005, a physician at the University of Wisconsin Hospital and Clinics, Madison, WI administered a 48 mCi dose of Y-90 Zevalin to a patient. Based upon patient weight and platelet count, the intended dose should have been 28 mCi. The dose was dispensed as a unit dose by a nuclear pharmacy and administered as received. There is no indication of a written directive. The error was not discovered until Thursday, April 7 during a licensee review of records.
"The licensee is investigating the incident. The ordering physician has been notified
"HFS 157.72 (1) (a) 1. requires a licensee to report an event in which the administration of radioactive material or resulting radiation results in 'A dose that differs from the prescribed dose by more than 0.05 Sv (5 rem), 0.5 Sv (50 Rem) to an organ or tissue or 0.5 Sv (50 rem) shallow dose equivalent to the skin and the total dose delivered differs from the prescribed dose by 20% or more'.
"DHFS, RPS staff plan to investigate. " |

The following information was provided by the State of CA via e-mail (text in quotes):
"At 12:35 pm [the] manager of the [Saddleback Memorial Hospital] Imaging Department contacted [the CA Radiological Health Branch] to report a therapy misadministration involving HDR and Ir-192. [The hospital manager] knew few details, other than to report that the source was apparently implanted 8 cm short of its desired location. At this time it is not known how much under treatment there was to the tumor site, nor how much exposure there was to healthy tissue. [It has] not been determined if this is a CA SS&D [Sealed Source and Device]. [The hospital manager] is obtaining this information and will be reporting it back, via fax, as soon as possible. [The CA Radiological Health Branch] has requested narrative as to flow of events.

"At 0352 the 2C 125VDC battery charger failed. Fuses internal to the charger were found blown. Technical Specifications require restoration of the charger within 2 hrs or enter Mode 3 within the next 12 hrs and Mode 4 within the next 36 hrs. Investigation has not been able to restore the charger, and therefore the shutdown of the unit has commenced. Loads are currently being carried by the batteries, and personnel are monitoring battery voltage. Initial investigation has not identified any generic issues or any indication of tampering.
"This event is a Technical Specification required shutdown, and is reportable as a four hour ENS Notification under 10 CFR 50.72(b)(2)(i). Additionally, this is a voluntary notification due to an anticipated press release associated with the downpower towards unit shutdown."
There is evidence of degraded insulation on wires inside the affected battery charger. Battery loads are very small with an initial estimate of battery life at 80 hours. All safety systems are operable. There is no impact on Unit 1.
Unit 2 is expected to reach Mode 3 at 1720 on 4/10/05.
The NRC Resident Inspector has been notified. State (FEMA) will be notified.

"At approximately 1604 CDT on 4/11/05, Cooper Nuclear Station (CNS) was informed by Emergency Preparedness officials of Atchison County that the radio transmission tower that provides signals to activate tone alert radios within the 10-mile Emergency Planning Zone (EPZ) was not functioning. Tone alert radio is relied on by approximately 650 households in the EPZ who are not in audible range of sirens for notification of an emergency at CNS. Based on a total EPZ population currently estimated at 4600 persons (who are alerted principally by sirens and the tone alert radio), this is considered to be a major loss of the Public Prompt Notification system capability, and is reportable under 10CFR50.72(b)(3)(xiii).
"Investigations are ongoing, a repair technician has been dispatched to the tower. During the interim, compensatory measures have been verified to be in place via state and local emergency planning officials for backup route alerting for personnel within the 10-mile EPZ."
NRC Resident Inspector was notified.

"22:53 on 4/11/05- CNS was notified by the NWS [National Weather Service] that the transmitter had been returned to high power service at 19:35. The cause of the high power transmitter loss was a lightning strike to the transmitter. The strike did not result in any equipment damage, however the transmitter had to be manually reset.
"22:55 on 4/11/05- CNS contacted Nemaha and Richardson County Sheriff's Departments and the Atchison County 911 center to notify them that the transmitter/tower had been returned to service.
"Operation of equipment was verified. Transmitter tower and tone alert radios have been returned to service."

"(A): The specific train(s) and system(s) that were actuated.
"This report is being made under 10 CFR 50.73(a)(2)(iv)(A). On February 19, 2005 at 05:50 ET the implementation of a clearance to de-energize the Division 1 24/48 VDC battery chargers were being performed using the system operating procedure. The clearance instructions were misinterpreted and the section of the procedure for de-energizing Division 1 24/48 VDC bus was used. Upon de-energizing the bus, a half scram was received, all 4 Standby Gas Treatment (SBGT) fans auto started and both unit ONE and unit TWO reactor building and refueling floor normal ventilation systems automatically shutdown/isolated.
"(b) Whether each train actuation was complete or partial.
"The 1/2 scram was a partial initiation of the RPS system logic. No control rods inserted as a result of this event, nor were they required to insert. The RPS logic functioned as expected during the 1/2 RPS trip.
"The 4 Standby Gas Treatment (SBGT) fans auto started and both unit ONE and unit TWO reactor building and refueling floor normal ventilation systems automatically shutdown/isolated. THE SBGT initiation and the ventilation system shutdown were both complete actuations.
"(C) Whether or not the system started and functioned successfully.
"The above systems functioned successfully."

| Event Text POSSIBLE MEDICAL EVENT
The VA National Health Physics Program (master materials licensee) reported a possible medical event at one of its permittees involving a Co-60 teletherapy device. The possible event occurred at the VA North Texas Health Care System, Dallas, Texas, on the dates of April 9 and 10, 2005.
"A patient was treated on Saturday and Sunday, April 9 and 10, 2005, for spinal cord compression. The written directive prescribed a dose of 500 cGy in two equal daily fractions. The intent was to give a total dose of about 2900 cGy, with another directive for the remainder of the fractions to be written on April 11, 2005. The treatment time for the fractions on April 9 and 10, 2005, was miscalculated. 330 cGy were administered instead of the prescribed 500 cGy. To avoid too low a dose, an additional fraction of 200 cGy will be given to the patient. This would not have met the definition of a medical event had a single directive, instead of two, been written for the entire treatment series.
"No adverse effect to the patient from the event is expected. The permittee has notified the referring physician and patient."
The licensee will notify the NRC Region III Project Manager (Kevin Null). | |
