Dick Odegaarden Introduction A meeting was held at the request of Nuclear Assurance Corporation (NAC) at Silver Spring, Maryland, on September 2,1987, concerning the Model No. NAC-1 cask.
Discussion Model No. NAC-1 Cask l
On September 2, 1987 NAC meet with NRC staff member to discuss two unrelated incidents with Model No. NAC-1 casks.
In the first incident a cask cavit.y vent valve was accidently left open due to operator error.
Because of the nature of the fuel being transported (dry) and the closure of the valve box by a cover, no significant radioactivity was released.
The valve box is being modified to reduce the possibility of operator error.
In a second incident, the lid of an " empty" cask lid was welded closed by DOE because of primary lid gasket failure.
(The DOE facility lacked provisions to remove the lid and replace the gaskets.) NAC discussed steps they are planning to take to restore the cask to service.
Because of the welding and subsequent weld removal the cask no longer meets the drawing dimensions required by the package certificate of compliance.

The Files NAC will submit the repair procedures in writing to NRC prior to the actual repairs.
It appears based on visual and leak tests that the lid seal area was not effected.
