Event Notification Report for April 02, 2009

LOST AMMONIA ANALYZER

Cormetech Inc. was unable to locate an ammonia analyzer containing 10mCi of Ni-63 during a routine inspection on April 2, 2009. The manufacturer of the instrument is Environmental Technologies Group. The instrument is a FP-IMS/CEM Ammonia Analyzer Model 221.

The licensee is taking action to locate the item but it is believed that the item is lost.

NC Incident: 09-21

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.

This source is not amongst those sources or devices identified by the IAEA Code of Conduct for the Safety & Security of Radioactive Sources to be of concern from a radiological standpoint. Therefore is it being categorized as a less than Category 3 source

RESIDUAL HEAT REMOVAL INOPERABLE

"At 0543 [CDT] on April 2, 2009 at the Monticello Nuclear Generating Plant (MNGP) an Operator made the following discovery during performance of his rounds. The flowrate and pressure of the #14 Residual Heat Removal Service Water (RHRSW) pump motor cooling appeared to be low. Investigation found the flow to be approximately 1 gpm. The cooling water supply flow to the pump motor cooler comes from either RHRSW or Service Water. Based on these indications, Operators declared the RHR Shutdown Cooling inoperable and entered actions for Technical Specifications 3.9.7. Actions have been completed to provide an alternate water supply to the RHRSW pump motor oil cooler. Based on the inoperability of the RHR Shutdown Cooling, this event is reportable under 10 CFR 50.72(b)(3)(v), 'An Event or Condition that could have Prevented the Fulfillment of a Safety Function-Capability to Remove Residual Heat.' The station is performing further investigation into the event and will develop corrective actions based on the results of the investigation."

The Licensee notified the NRC Resident Inspector.

"Monticello is retracting the event reported based on further evaluation. An investigation of the event found test data that demonstrates the RHRSW pump would not have lost its ability to provide cooling water to the shutdown cooling system and therefore no loss of safety function occurred. The test data provides documentation that the thrust bearing oil bath temperature of the RHRSW pump motor would not have exceeded the 200 deg F limit imposed by the motor supplier (GE) at the flow rate found by the operator. The test data indicated with the cooling water at a flow rate of less than 0.9 GPM, at 65 deg F the service water temperature and flow would be sufficient to maintain the motor oil bath temperature below 200 deg F. During the event, the actual event parameters (cooling water flow rate >1 gpm and temperatures< 65 deg F) were less severe than the test parameters and therefore are bounded by the test.

"Since there was no impact on the RHRSW system's ability to provide cooling water to the RHR system, the RHR system maintained the ability to provide shutdown cooling and residual heat removal. Therefore the event can be retracted since the condition that was reported in the initial event notification report would not have resulted in the prevention of the fulfillment of a safety function (residual heat removal)."

The licensee notified the NRC Resident Inspector and will notify the State of Minnesota.

AGREEMENT STATE REPORT - TWO PATIENTS GIVEN IODINE-123 TREATMENTS ABOVE PRESCRIBED AMOUNT.

The following information was received from the State of Florida via facsimile:

"During inspection it was found that two patients were given I-123 treatments greater than 20% of prescribed amount. The amount prescribed was 200 microcuries. The amounts given were 318 microcuries [for patient #1] and 314 microcuries [for patient #2]. [The State of Florida] Licensing and Materials Office is investigating this incident."
