An NRC-identified non-cited violation (
NCV) of
Technical Specifications, 5.5.16,
Control Room Envelope Habitability Program, was identified for failure to implement and maintain all provisions of the program. The seals on the control room doors were not being inspected and maintained as required. The performancy deficiency (
PD) was more than minor because, if left uncorrected, the seals could continue to degrade and challenge the
control room habitability envelope. The inspectors determined the finding was of very low safety significance (Green) because the lack of control room door seal inspections only represented a degradation of the radiological barrier function provided for the control room. The cause of this finding was related to the cross cutting-aspect of providing complete, accurate and up-to-date design documentation, procedures, and work packages of the Human Performance cross-cutting area because the necessary procedures and work packages were inadequate to assure compliance with the licensees
Control Room Envelope Habitability Program.
