WASHINGTON PUBLIC POWER SUPPLY SYSTEM DOCKET NO. 50-397 LICENSE NO. CPPR-93 SPECIAL DDORS AND HATCHES UPDATED REPORT Potential Problem Numerous nonconformances have been identified relative to Quality Class I special doors and hatches, which involve materials, fabri-cation, testing and documentation. These doors include water tight doors in the basement of the reactor building; airtight doors and hatches in the reactor and control building; and blast doors in the reactor and control building.

Failure of the doors and hatches to perform their intended function could adversely affect the safe shutdown and the control of radio-active releases during a design basis accident condition.

A question exists as to whether the doors and hatches would have failed in service if the indicated conditions had gone undetected.

NRC Region V was ' notified of the potential deficiency, by telephone on November 14, 1980.

Approach to Resolution of the Problem Evaluate all deficiencies for a particular door, hatch or sets of doors to determine if the deficiencies would have led to inservice failures. The evaluations will include non-destructive examinations of the hardware in conjunction with an engineering review of the vendors design calculations.

Isses direction for correction of all deficiencies as required to meet design criteria.

Status of Proposed Resolution The Engineering and Quality Assurance organizations of the WNP-2 Architect / Engineer have been working with the affected Contractor since March 1980 to identify, provide technical resolution, and close out deficiencies associated with the various types of special doors and hatches. A Management Corrective Action Request was transmitted to the Contractor on Octobar 27, 1980, documenting delays and requesting timely resolution.
