FITNESS FOR DUTY - CONFIRMED POSITIVE FFD TEST
A non-licensed, contract, supervisory employee had a confirmed positive for alcohol during a for-cause fitness-for-duty test. The employee's access to the plant has been terminated.
The licensee notified the NRC Resident Inspector.

UF6 PRESENT IN THE SMALL COMPONENT DECONTAMINATION TRAIN
"(1) Radiological or chemical hazards involved, including isotopes, quantities, and chemical and physical form of any material released Uranium-hexafluoride (UF6):
"3.1 grams of solid UF6 was present in the Small Component Decontamination Train (SCT) and was assumed to be enriched to 5 weight percent U235. Thus 0.16 grams of U235 were present. Neither criticality nor chemical release occurred.
"(2) Actual or potential health and safety consequences to the workers, the public, and the environment, including relevant chemical and radiation data for actual personnel exposures to radiation or radioactive materials or hazardous chemicals produced from licensed materials (e.g. level of radiation exposure, concentration of chemicals, and duration of exposure):
"None; the administrative limit to ensure criticality is prevented is 730 grams of U235. The mass present was about two ten-thousandths of the administrative mass limit. This administrative mass limit is less than one half of the analyzed 0.95 keff safe mass.
"(3) The sequence of occurrences leading to the event, including degradation or failure of structures, systems, equipment, components, and activities of personnel relied on to prevent potential accidents or mitigate their consequences:
"The IROFS prevent the accumulation of U235 above the administrative mass limit of 730 grams U235 in the SCT. The IROFS determine a net weight of residual material in a container by comparing the initial, prior to first use, tare weight to the empty weight, after outgassing.
"It was discovered that upon cleaning, the technicians were determining a net weight using the most recent empty weight, not the prior to first use tare weight. This resulted in the potential to nullify the weight of remaining trace quantities of residual material.
"This represents a failure of management measures such that no IROFS, as documented in the ISA summary, remain available and reliable, in an accident sequence evaluated in the ISA, to perform their function. Therefore, this one hour event report being completed in accordance with 10 CFR 70 Appendix A (a)(4).
"(4) Whether the remaining structures, systems, equipment, components, and activities of personnel relied on to prevent potential accidents or mitigate their consequences are available and reliable to perform their function:
"All structures, systems, equipment, components, or activities of personnel remain available and reliable to perform their safety functions.
"(5) External conditions affecting the event;
"There were no external conditions that affected this event.
"(6) Additional actions taken by the licensee in response to the event:
"The area was isolated, operations in the SCDT were halted and a criticality anomalous condition was declared per Operating Requirement Manual. An immediate reconciliation of the IROFS54a and 54b mass record logs was completed and it was determined that the mass present in the SCDT, 0.155 grams U235, was well below the administrative mass limit of 730 grams.
"(7) Status of the event (e.g., whether the event is on-going or was terminated);
"No event occurred; there was insufficient material present for criticality to be possible. No release of licensed material occurred. This event was the discovery of a failed management measures related to an IROFS.
"(8) Current and planned site status, including any declared emergency class;
"Plant is running at full capacity. This event did not warrant any change in plant status. No declared emergency occurred nor are any planned.
"(9) Notifications, related to the event, that were made or are planned to any local, State, or other Federal agencies;
"No notifications other than this report have been made nor are any planned.
"(10) Status of any press releases, related to the event that were made or are planned.
"No press releases have occurred nor are any planned."
