| Event Text AGREEMENT STATE REPORT INVOLVING A SPILL OF IODINE-131 (UNPLANNED CONTAMINATION EVENT)
"TDRH was notified on 02/11/04 of a spill involving I-131 at the Cardinal Health pharmacy in Chattanooga, TN. This event occurred during the afternoon on 02/04/04. An employee was transferring a stock bottle containing 97 millicuries of I-131 from the glove box to the fume hood. The employee dropped the lead pig and the contents of the vial were spilled. Two employees cleaned the area for approximately 20 minutes. Air samples were collected and bioassays of the workers were performed. The room was immediately closed off and access by personnel limited to once a day to collect air sampling media. The initial bioassay results were above the licensee's action limits but below regulatory limits. As of 02/10/04, bioassays results were below the licensee's action limits. The initial air sample collected 18 hours after the spill indicated a stack concentration of 6.5E-08 microcuries/ml. The area will remain restricted, under negative pressure, with fume hoods running. TDRH was notified by the Senior Manager of Health Physics from the corporate office in California. A written report from the licensee will be submitted within 30 days. This incident is reportable under 1200-2-5-.141(c)1(i) of" State Regulations for Protection Against Radiation".

The following information was received from the licensee via facsimile:
"At 1519 [CDT] on 2-15-04, the plant was at 20 power, increasing load. During the transfer from the bypass feedwater regulating valves to the main feedwater regulating valves, the main turbine tripped due to a P-14 S/G Hi-Hi level signal. The P-14 signal also caused a Feedwater Isolation Signal (FWIS), which resulted in a Motor Driven Aux Feedwater Actuation (MDAFAS), and Steam Generator Blowdown Isolation Signal.
"Steam Generator levels subsequently shrunk to low levels causing a Steam Generator low level reactor trip at 1524 [hrs]. Sometime after the turbine trip, the turbine driven aux feed pump [(TDAFP)] was manually started to help restore S/G levels. The pump was later manually secured, but then received a subsequent auto-start signal and tripped on overspeed. The TDAFP was declared inoperable at 1535 [hrs]. With the exception of the TDAFP, all safety systems operated properly.
"The plant is currently stable in Mode 3, with the primary plant at 557 deg F and 2235 psig, and pressurizer level at 25%."
The licensee has notified the NRC Resident Inspector.

The following information was received from the licensee via facsimile as a "rewrite of above paragraph 2."
"Sometime after the turbine trip, the Turbine Driven Aux Feedwater Pump (TDAFP) was manually started to help restore S/G levels. Due to decreasing reactor coolant system (RCS) temperature, it was decided to stop the TDAFP since it is a steam load. The steam supply valves were remote manually closed from the control room. At the same time the steam supply valves were closing, the steam generator levels shrunk to low levels causing a Steam Generator low level reactor trip and Turbine Driven Aux Feedwater Actuation (TDAFAS) at 1524. The steam supply valves immediately reopened due to the TDAFAS. It is postulated that this transient in the steam supply caused the pump to overspeed trip. The TDAFP was declared inoperable at 1535. With the exception of the TDAFP, all safety systems operated properly."
The licensee notified the NRC Resident Inspector.

At 0225 EST on 02/16/04, the licensee declared an Unusual Event due to the instrument air/service air system service air compressor controller exploding due to an electrical fault. Instrument air compressor alarm #H-16 actuated. The backup 'A' and 'B' instrument air compressors auto started. The licensee immediately electrically isolated the service air compressor controller. The licensee declared the Unusual Event in accordance with EAL 8.3.2, an explosion or detection of explosion affecting plant equipment or structures within plant protected area boundaries. No other plant equipment or structures were affected. The plant is stable at 100% power. There is no indication of tampering or foreign objects inside the controller. The licensee is investigating the cause. The licensee notified the NRC Resident Inspector and State and Local Officials. The licensee does not plan to issue a press release.
* * * Update at 0425 EST on 02/16/04 from John White to Jolliffe * * *
At 0420 EST on 02/16/04, the licensee terminated the Unusual Event based on the service air compressor controller being electrically isolated and removed from service and the surrounding area secured. The licensee is continuing to investigate the cause of the electrical fault. Plant security personnel determined in accordance with their security tampering procedure that this event is clearly not security related. The licensee notified the NRC Resident Inspector and State and Local Officials of the termination of the Unusual Event.

| Event Text PART 21.21 NOTIFICATION OF POTENTIAL SAFETY HAZARD ASSOCIATED WITH USE OF TURBOCHARGER
"On February 12, 2004, Fairbanks Morse Engine evaluation determined a potential safety hazard associated with the use of ABB turbocharger model VTC-304 on OP engines only.
"Torsional resonance has been found in the rotating assembly which is excited by exhaust pulses. The resonance manifests itself as either a bent or broken shaft, slipped compressor wheel, cracked compressor wheel or complete rupture of the compressor set. Once failure occurs, engine power cannot be sustained.
"This condition is corrected by machining the rotating assembly to tune the natural frequency away from operating conditions.
"The only affected site is Crystal River 3. (6) turbos have been shipped to this site. None of the turbos have been installed and all are in storage. The FM parts department will arrange to have the turbos returned to the factory to have the necessary machining performed." | |
