Title

Failure to Make a Required 10 CFR 50.72 Report for an Inoperable Secondary Containment

Description

A Severity Level IV NCV of 10 CFR 50.72(b)(3)(v) was identified by the inspectors for the licensees failure to report an event or condition that could have prevented the fulfillment of the secondary containments safety functions, which are relied upon to control the release of radioactive material. Specifically, the licensee had not properly controlled the opening of two airlock doors that served as a boundary to maintain the ventilation envelope of the reactor building. The licensee entered this issue into its CAP as ARs 1182255 and 1195987, and, at the time of this report, was in the process of conducting an apparent cause evaluation to determine the causes of the occurrence and to develop corrective actions. Violations of 10 CFR 50.72 are considered to be violations that potentially impact the regulatory process and are dispositioned using the traditional enforcement process instead of the Reactor Oversight Process SDP. As such, a cross-cutting aspect was not assigned to this violation.
