| Event Text PART 21 REPORTABLE CONDITION AND 60-DAY INTERIM REPORT NOTIFICATION: NON-CONSERVATIVE SAFETY LIMIT MINIMUM CRITICAL POWER RATIO
Global Nuclear Fuel (GNF) and GE Nuclear Energy (GENE) have determined that the current GNF process for determination of the Safety Limit Minimum Critical Power Ratio (SLMCPR) can result in a non-conservative SLMCPR. GENE has historically used a non-conservative SLMCPR impact of 0.01 as the threshold for reportability under 10CFR21. A preliminary screening evaluation has been completed for all plants operating with a SLMCPR calculated by GNF to determine those that have a nonconservative impact of 0.01 or greater. Verification has been completed for those plants that the screen showed to have a non-conservative SLMCPR impact of 0.01 or greater. Verification has not been completed for the plants that the screen showed had an impact of less than 0.01 or were unaffected, thus requiring a 60-Day Interim Report notification pending verification completion.
The plants for which GNF calculates the SLMCPR are identified [below]. Those plants for which the preliminary screen indicated that the current SLMCPR is unaffected are identified as a 60-Day Interim Report. Upon completion of verification (assuming the results of the screen are confirmed) the status of these plants will be changed to Not Reportable. GENE will provide a follow-up report to the NRC by September 29, 2004. The plants for which the current SLMCPR is non-conservative by 0.01 or greater are identified as a Reportable Condition under 10CFR21.21(d). These plants will take action to address the Reportable Condition.
GNF has notified all plants that have been confirmed to be affected. The plants that have a non-conservative SLMCPR for current plant operation will take action to mitigate the potential impact. Depending on the specific circumstances, mitigating actions to protect the SLMCPR may include increasing the OLMCPR to assure compliance with the low flow calculated SLMCPR. In some cases sufficient conservatism may exist in the OLMCPR at low flow to bound the increased SLMCPR. Each affected plant will notify the NRC and take appropriate action if their Technical Specifications are affected.
There are no actions necessary for the plants that are unaffected pending completion of verification. If, in the course of verification, GNF determines that there is an impact, the affected utility will be notified immediately. GNF will complete the verification and GENE, will provide a follow-up letter to the NRC by September 29, 2004.
Affected and 60-Day Interim Notification Plants:
60-Day Interim Report: Clinton, Oyster Creek, Brunswick 1, Brunswick 2, Nine Mile Point 2, Fitzpatrick (60-Day interim report for current operation, Reportable Condition for SLMCPR licensing submittal), Pilgrim, Vermont Yankee, Dresden 2, Dresden 3, LaSalle 1, LaSalle 2, Limerick 1, Limerick 2, Peach Bottom 2, Peach Bottom 3, Quad Cities 1, Quad Cities 2, Perry 1, Duane Arnold, Monticello, Hope Creek, Hatch 1, Hatch 2, Browns Ferry 2
Reportable Condition: Nine Mile Point 1, Fermi 2, Fitzpatrick (60-Day interim report for current operation, Reportable Condition for SLMCPR licensing submittal), Cooper.
* * * UPDATE FROM JASON POST (VIA FAX) TO CROUCH @ 2354 HRS. EST ON 09/29/04 * * *
In part, the update reads:
"The evaluation for the potentially unaffected plants has now been completed. The results of the screening calculation have been confirmed: this is not a reportable condition for the plants that were previously identified as a 60-Day Interim Report notification in MFN 04-081" (See above).

"At 1445 on September 8, 2004, while in Mode 3 after an unplanned reactor trip during tropical storm Frances, Crystal River Unit 3 experienced a re-actuation of the B-Train of the Emergency Feedwater System. The Emergency Feedwater System had previously actuated during a Loss of Offsite Power experienced during Hurricane Frances and the B-Train actuation had procedurally been bypassed as part of the plant recovery. While In the process of restoring a Main Feedwater Pump to an operating condition, the signal bypassing the B-Train Emergency Feedwater actuation was momentarily removed due to unusual plant conditions present during recovery from the loss of power This resulted in the re-actuation of the B-Train of Emergency Feedwater. This condition is 8-Hour reportable per 10CFR50.72(b)(3)(iv)(B)(6). The re-actuation of the B-Train of Emergency Feedwater did not have a significant impact on plant operation and the associated equipment has been returned to a standby condition."
The licensee informed the NRC Resident Inspector.

The following information was provided by the licensee via facsimile:
"At 1823 [hrs. EDT] on 9/8/04, Crystal River Unit 3 made an 8-hour ENS notification in accordance with 10CFR50.72(b)(3)(iv)(A) and 50.72(b)(3)(iv)(B)(6) concerning re-actuation of the B-train of the Emergency Feedwater System. The Emergency Feedwater System had previously actuated during a Loss of Offsite Power experienced during Hurricane Frances and the B-Train actuation had procedurally been bypassed as part of the plant recovery. While in the process of restoring a Main Feedwater Pump to an operating condition, the signal bypassing the B-Train Emergency Feedwater actuation was momentarily removed due to unusual plant conditions present during recovery from the loss of power. This allowed for a re-actuation of the B-Train of Emergency Feedwater based on a loss of Main Feedwater Pump signal. However, the two Main Feedwater Pumps had not been operating since the loss of offsite power that occurred on 9/6/04. The A-Train Emergency Feedwater System had been operating continuously since the initial actuation on the loss of offsite power and continued to operate during and after the re-actuation of the B-Train. Re-actuation of the B-Train has been determined to be an invalid actuation in accordance with the guidance of NUREG-1022, and therefore EN 41027 is retracted."

| Event Text AGREEMENT STATE LOST OHMART DENSITY GAUGE
"The licensee reported that an Ohmart density gauge (Model SH-F2, Serial Number 2479GK) had last been seen during an inventory and shutter check on November 17, 2003. The gauge contained a 1.85 GBq (50 mCi), Cs-137 sealed source. Facility records indicate the device's electrical signal was lost on December 12, 2003, at 4:30 pm. At that time, a physical investigation, to investigate the signal loss, was not performed. The next routine inventory was attempted on May 17, 2004. At this time the gauge was found to be missing.
"The missing gauge had measured 'weight rejects' at a remote part of the facility. Rejects are routinely sent to an eastern Washington landfill by truck. The gauge seems to have been dislodged from its angle-iron attachment, by large reject material, and then inadvertently taken to an eastern Washington landfill by the rejects truck.
"Gauge measurements were not vital to operations, so the loss of signal had gone ignored until the May 17th inventory attempt.
"CORRECTIVE ACTION TAKEN by licensee:
1. A special training session will be given, during the licensee's next monthly safety meeting, for those employees associated with fixed gauge operations. The training will emphasize the importance for employees to investigate when gauge process measurements are lost.
2. Special informational postings will be placed at key locations within the facility, near process control equipment receiving fixed gauge electrical signals, so facility employees shall be reminded to immediately investigate the loss of a gauging device's signal.
"Isotope and Activity Involved: Cs-137, 1.85 GBq (50 mCi)
"Overexposures? (number of workers/members of the public; dose estimate; body part receiving dose; consequence): None likely.
"Lost, Stolen or Damaged? (mfg., model, serial number): Lost (or Stolen) Ohmart density gauge (Model SH-F2, Serial Number 2479GK)
"DISPOSITION/RECOVERY: Searches by licensee with the assistance of department staff were performed with Ludlum Model 19, Micro R meters and other detection instrumentation. These searches were unsuccessful.
"A search at the Licensee's facility in Port Townsend, Washington was conducted on May 25, 2004. A search at the landfill was performed on July 29, 2004."

"Per Swedish Medical Center policy, post thyroid treatment patients are prescribed 74 mBq (2mCi (milliCuries)) for the treatment follow-up scan, and 185 mBq (5 mCi) for subsequent treatment if necessary. On 24 September 2004 a patient was prescribed 74 mBq (2 mCi) of NaI (Iodine-131) for a post treatment scan. Instead, 191 mBq (5.16 mCi) of NaI (Iodine-131) were administered. The prescribing physician realized that a misadministration had occurred on 27 September 2004 when the patient underwent the scan. A viable follow-up scan was able to be performed even though the misadministration had occurred.
"There are multiple procedural checks in place to assure medical technicians administer the prescribed dose. Human error appears to have lead to checks not being performed prior to this event.
"The Radiation Safety Officer for Swedish Medical Center notified the State of Washington, of the misadministration, on 27 September 2004.
"The treating physician notified the patient on Monday, 27 September 2004, when the physician discovered the patient had been administered 191 mBq (5.16 mCi) of NaI (Iodine-131) instead of the prescribed 74 mBq (2 mCi) of NaI (Iodine-131)."
