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. |

Baylor University identified a leaking Americium-241 sealed source. They were preparing the source for shipment to Los Alamos as part of the lost source recovery program when they identified leakage during a leak test. The state received conflicting information from the licensee who said that the activity of the source was either 1 millicurie or 191 millicuries. No further information was available at the time of the report. The state will follow up on this report with additional information after they gather it.
* * * UPDATE FROM A. TUCKER TO P. SNYDER AT 1301 ON 5/2/06 * * *
There were no personnel consequences as a result of this incident. No uptakes were reported. The source, ICN serial number 74101, was a one inch diameter check source that was being prepared for shipment to the Los Alamos National Laboratory off-site recovery program on 4/25/06. The source was in storage for some period of time immediately prior to being prepared for shipment. The activity of the source is 0.1909 microcuries of alpha and 0.0234 microcuries beta/gamma.
"The [licensee's] radiation safety staff isolated the source in a sealed container and surveyed all areas to ensure that the facility and other articles in contact with the source have not been contaminated. A contractor has been secured to encapsulate the source so that it can be disposed of."

"Greater than one percent of steam generator (SG) 2-4 tubes were determined to be defective and require plugging. Diablo Canyon performs 100% bobbin inspection of SG tubes, thus, no expanded bobbin inspection scope was required.
"On May 3, 2006, during the Unit 2 thirteenth refueling outage (2R13), final analysis of eddy current data of SG 2-4 indicated that greater than one percent of the total tubes inspected were defective placing them in Category C-3. Thirty four (34) detective tubes in SG 2-4 were detected and are being plugged. Most of the pluggable indications are due to axial outside diameter stress corrosion cracking at the hot leg tube support plates. Diablo Canyon TS 5.5.9, Table 5.5.9-2, requires 'Notification to NRC pursuant to 10 CFR 50.72(b)(2)' (replaced by 10 CFR 50.72(b)(3)(ii), an 8-hour non-emergency ENS report requirement).
"An NRC teleconference in accordance with TS 5.6.10.d to report the preliminary SG tube inspection results is scheduled for May 3, 2006, at 1000 PDT.
"A Special Report in accordance with TS 5.6.10.a to report the number of tubes plugged in each SG, and TS 5.6.10.c describing the cause of the tube degradation and corrective measures taken to prevent recurrence will be submitted prior to returning Diablo Canyon Unit 2 to power operation."

"This report is being made pursuant to 10CFR50.72(b)(3)(xiii), 8-hour Non-Emergency Report due to the loss of off-site response capability. As of 0700 Central Daylight Savings Time on 5/03/2006 the TSC was declared non-functional due to the discovery of non-conservative surveillance acceptance criteria for the TSC ventilation system flow balance. The acceptance criteria allow for a higher percentage of pressurization flow from filtered outside air and lower recirculation flow than is supported by the radiological consequences analysis for the TSC. This condition is complicated by the fact that the radiological consequences analysis has not been updated to incorporate changes to plant operation and radiological source term derived from the current license basis Loss of Coolant Accident analysis. Preliminary evaluations using current plant configuration, current TSC ventilation flow balance values, and current calculation methodology indicate that post-accident dose to TSC personnel is approximately 31.7 Rem to the thyroid, exceeding the acceptance criterion of 30 Rem.
"Activities to revise applicable surveillance acceptance criteria and restore TSC functionality by re-balancing TSC ventilation flows to establish acceptable dose consequences have been initiated and are expected to be complete by 2000 on 5/3/2006. Affected Emergency Response Organization members have been instructed on compensatory measures in place until the TSC is fully functional.
"Callaway Plant is currently operating in Mode 1 at 100% power. Normal plant operation is unaffected by the partial loss of TSC function.
"The licensee has notified the NRC Resident Inspector."
* * * UPDATE FROM F. BIERMANN TO P. SNYDER AT 2036 ON 5/3/06 * * *
"TSC ventilation flow balancing activities to restore TSC functionality have been completed. The TSC was declared functional and restored to service at 1930 CDT on 5/3/06."
The licensee will inform the NRC Resident Inspector.
