Finding

Title

LICENSEE-IDENTIFIED Violation

Description

Technical Specification 5.7.2 requires each entryway to an area with dose rates greater than 1.0 rem/hour at 30 centimeters from the radiation source or from any surface penetrated by the radiation be provided with a locked or continuously guarded door or gate that prevents unauthorized entry, and doors and gates shall remain locked except during periods of personnel or equipment entry or exit. Contrary to this requirement, on March 23, 2012, during routine walkdowns, the licensee identified the locked high radiation area door into the reactor coolant pump room 2-2 area, on the 115-foot elevation, was not secured. Although the mechanism locked, the door was ajar and opened when pulled. The licensee confirmed the locking mechanism operated properly. The condition had existed since the first week of June 2011. The licensee acknowledged dose rates in the area during operation were as high as 2 rem/hour because of the presence of nitrogen-16. Using the Occupational Radiation Safety Significance Determination Process, the inspectors determined the finding had very low safety significance because: (1) it was not an as low as is reasonably achievable finding, (2) there was no overexposure, (3) there was no substantial potential for an overexposure, and (4) the ability to assess dose was not compromised. The licensee documented the violation in the corrective action program as Notification 50468048.
