INADEQUATE SERVICE WATER SYSTEM FLOW TO EDGs (HISTORICAL REPORT)

"On June 2, 2000, Kewaunee completed a scheduled refueling outage. During the outage, comprehensive flow data was measured on the plant's service water system. Subsequent analysis of the flow data revealed that for less than one hour on August 8, 1991, both of the redundant diesel generators could have had cooling water flow below design basis post-accident requirements. The cause of the condition is a combination of elevated cooling water temperatures, conservative calculation assumptions using recent data, and a previously unidentified design problem that results in reduced flow through the diesel coolers. The design problem occurs due to system backpressure caused by the diesels' cooling water discharges being connected to a common header. During the outage, the diesel generator heat exchangers were replaced for reasons unrelated to this report. The new heat exchangers' increased capacity precludes recurrence."

The NRC resident inspector has been informed of this event by the licensee.

POTENTIAL PERSONNEL OVEREXPOSURE OF A CONTRACT EMPLOYEE AT SOUTHEAST MISSOURI STATE UNIVERSITY IN CAPE GIRARDEAU

HOO NOTE: Information regarding the same event was reported to the NRC Operations Center on 09/01/00 by Engelhardt & Associates. (Refer to event #37282.)

The licensee was advised by the NRC Region 3 Office to followup on the report made by Engelhardt & Associates because the work was performed on the Southeast Missouri State University Campus. The licensee is making this notification because they want to document that they are aware of this issue and that they agree with the Engelhardt & Associates report. Another reason for the report is that there may be an issue of who the responsible party is at this point in time.

As a result of an NRC visit in February, Southeast Missouri State University discovered that a spill had occurred in the basement of Magill Hall. Accordingly, Engelhardt & Associates was contracted to perform several tasks including cleanup of the spill. At the time, the spill was thought to be minor, and the licensee has since found out that the spill was quite major. In addition to cleanup of the spill, Engelhardt & Associates was contracted to help the licensee get ready for a waste haul and help prepare a new Radiation Plan. An Engelhardt & Associates representative arrived on 06/12/00, and he worked in (and out) the basement of Magill Hall for 5 days.

On 09/01/00, the NRC Region 3 Office (Kevin Null) notified the licensee that the Engelhardt & Associates employee had received a dose of 9 REM CEDE. As a result, the licensee is in the process of trying to arrange followup testing for the Engelhardt & Associates employee. The licensee has also hired another firm (SAIC) to cleanup some areas of Magill Hall because of a secondary spill that occurred quite some time ago. SAIC representatives have been on campus for a 1-week period already and are expected to return to the campus on 09/18/00. SAIC will also be handling the licensee's dose assessment.

Call the NRC operations officer for licensee contact information.

* * * UPDATE ON 2/13/02 FROM WALT LILLY TO MIKE RIPLEY /HOWIE CROUCH * * *

Final bioassays and lung counts from individuals exposed during the above incident indicate that another individual had an intake of Am-241. This individual received an estimated intake of 9.4 nanocuries with a final dose assigned of 76 REM CDE to bone surfaces and 4.2 REM CEDE. The individual is undergoing chelation therapy at this time.

AN EMPLOYEE OF A RADIATION CONSULTING FIRM MAY HAVE RECEIVED A PERSONNEL OVEREXPOSURE

ENGELHARDT & ASSOCIATES, INC. WAS HIRED BY SOUTHEAST MISSOURI STATE UNIVERSITY LOCATED IN CAPE GIRARDEAU, MO. TO ASSESS AND UPGRADE THE UNIVERSITY'S RADIATION SAFETY PROGRAM. SEVERAL YEARS BEFORE THE UNIVERSITY INFORMED THE NRC THAT A COUPLE OF AMERICIUM-241 SOURCES HAD BEEN REMOVED. DURING AN NRC RIII INSPECTION LATE LAST YEAR, THE SOURCES WERE FOUND ON CAMPUS. DURING THE CONSULTANTS ASSESSMENT, HE DISCOVERED THAT ONE OF THE SOURCES HAD BEEN SPILLED (LIQUID FORM) CAUSING A LARGER PROBLEM THAN INITIALLY BELIEVED. THE EMPLOYEE'S UPTAKE WAS DETERMINED BY ARGONNE NATIONAL LAB TO BE ON THE ORDER OF 9 REM CUMULATIVE DOSE EQUIVALENT. NRC REGION III (WRIGHT, JORGENSEN) WAS INFORMED BY ENGELHARDT.

HOO NOTE: Information regarding the same event was reported to the NRC Operations Center on 09/07/00 by Southeast Missouri State University. (Refer to event #37298.)
