Drill a.
Pre-drill Activities Prior to drill initiation, the inspector reviewed the nature and scope of the drill scenario, which involved a steam generator tube rupture resulting in an off-site release.
No inadequacies were identified.
b.
Drill Observation The NRC inspectors made detailed observations of the following activities.
(1) Control room actions concerning detection and response to the simulated emergency conditions; (2) Notification of plant personnel and offsite agencies; (3) Plant evacuation; (4) Accident assessment actions; (5) Communications;
(6) Coordination and control of response actions; and, (7) Security force actions.
c.
Drill Results The inspectors attended a post-drill critique, during which drill participants, licensee observers, offsite agency personnel and the inspectors discussed ths drill results and highlighted areas needing further evaluation for possible improvement.
,
The inspectors determined that:
the licensee's response was generally in accordance with approved procedures; the response was observed and evaluated by qualified licensee personnel; and the observer comments, including those of the inspectors, were documented for further evaluation and resolution, as appropriate.
During the drill critiate, the inspectors made the following re-commendations:
(1) To improve the realism of the operator responses, avoid providing the complete scenario to the operators.
(2) Operators should provide the most complete information available when an emergency is announced.
In this scenario, the Emergency Cocrdinator was unaware that a steam generator relief had stuck open and was the primary release path off-site.
(3) Operators should receive indoctrination in worst case analyzed accidents so that they can more easily classify accidents as Local, Site, or General Emergency.
3.
Radwaste Shipment Discrepancy The in:pector reviewed Radwaste Shipment Discrepancy Report for shipment RSR 79-20 with the Plant Health Physicist.
This shipment had arrived at Barnwell site with no chains, binders, or tie-downs attaching the cask to the trailer.
Since the shipment contained less than Type A quantities of radioactive materials, a Radwaste Shipment Quality Assurance Record was not completed when the shipment left the site.
The licensee plans to change procedure MY-HP-108-79, to require this record for all radwaste shipments and to include a verification that the tie-down system is properly attached prior to releasing a shipment.
This item will be followed up in a subsequent inspection.

4.
Plant Tour The inspectors performed a tour of accessible areas of the plant including the Turbine Building, Control Room, Emergency Diesel Generator Rooms, the HP Control Point, Primary Auxiliary Building, and Spent Fuel Pool. The inspectors reviewed housekeeping and cleanliness, adequacy of health physics controls, and compliance with operator manning requirements of Technical Specifications.
In addition, a valve / switch lineup verification was perfonned for Diesel Generator 18 fuel oil, starting air, secondary component cooling, and automatic start circuitry.
No items of noncompliance were identified.
5.
IE Bulletin 79-18 Followup This Bulletin concerns audibility of the plant evacuation alarm in high noise areas. The plant has identified several areas inside the plant as well as the guard towers and temporary trailers where this problem exits. The licensee plans to incorporate administrative controls into the Emergency Phn to insure that people in these areas are informed of facility emergencies until additional paging equipment can be procured and installed. This item will be followed up in a subsequent inspection.
