| Title | Supervisors apparent willful violation of a DAEC refueling procedure. |
| Description | This refers to the investigation conducted by the U.S. Nuclear Regulatory Commission (NRC) Office of Investigations (OI) at the Duane Arnold Energy Center (DAEC) that was completed on October 26, 2005. The investigation concerned a former supervisors apparent willful violation of a DAEC refueling procedure on November 9, 2004. In that instance, the former supervisor failed to complete a Pre Fuel Move Checklist, as required by a DAEC fuel handling procedure before moving three irradiated fuel bundles in the DAEC spent fuel pool. A summary of the OI report was provided to you on March 9, 2006. In the letter transmitting the summary of the OI report, we provided you the opportunity to address the apparent violation described in that letter by either attending a predecisional enforcement conference (PEC), providing a written response, or requesting alternative dispute resolution (ADR) before we made our final enforcement decision. On March 15, 2006, you indicated that a PEC would not be necessary, you would not be requesting ADR, and a written response would be submitted. In a letter dated April 7, 2006, you provided a written response to the apparent violation. Based on the information developed during the investigation and the information that you provided in your April 7, 2006, letter, the NRC has determined that a violation of NRC requirements occurred. The violation is cited in the enclosed Notice of Violation (Notice) and the circumstances surrounding it described in the summary of OI Report No. 3-2004-033 provided to you on March 9, 2006. In summary, DAEC Refueling Procedure No. 403, Performance of Fuel Handling Activities, Revision No. 16, was issued on June 16, 2004, and required that the designated fuel handling supervisor complete applicable sections of the Pre Fuel Move Checklist before starting fuel handling activities. On November 9, 2004, a refueling floor supervisor, who was primarily responsible for preparing Revision No. 16 to the procedure, was the designated fuel handling supervisor and he failed to complete the Pre Fuel Move Checklist before moving three irradiated fuel bundles in the DAEC spent fuel pool, as required by the refueling procedure. Based on the information developed during the OI investigation, it appears that the refueling floor supervisor had sufficient understanding of the procedural requirement to complete applicable sections of the Pre Fuel Move Checklist before starting fuel handling activities on November 9, 2004. Also, the refueling floor supervisor was experienced in refueling floor activities and was appropriately trained for the movement of G. Van Middlesworth irradiated fuel in the spent fuel pool. Therefore, this is considered to be a willful violation, demonstrating at least careless disregard of a procedure required by DAEC Technical Specification 5.4.1, and the violation has been categorized in accordance with the NRC Enforcement Policy at Severity Level III. |
