SUBJECT: ENVIRONMENTAL QUALIFICATION OF SAFETY-RELATED EQUIPMENT
The NRC has initiated a program to audit the testing of equipment for
environmental qualification. It includes the witnessing of equipment tests,
and independent verification testing by the NRC. The long range goals of
this program are the standardization of qualification criteria,
accreditation of testing facilities, and improvement of environmental
testing specifications and standards. This program is part of the overall
effort to ensure that the equipment will perform its safety-related function
in the harsh environment resulting from accidents.
For pre-selected pieces of equipment, the entire test program will be
reviewed. This will include specimen selection and preparation, test
procedure review, acceptance criteria review, observation of the test, and
issuing a Safety Evaluation Report. Industry cooperation is important for
these tasks.
To assist in planning and scheduling this effort, you are requested to
provide pertinent information relative to environmental qualification tests
to be conducted within the next two years on equipment used or to be used in
your facilities. This information should include:
1. Equipment description (type, model, manufacturers etc.)
2. The system where the equipment is installed (including Unit name)
3. The test location and schedule
4. The cognizant licensee contact for the test.
You are requested to voluntarily supply this information to this office with
a copy of the response to the appropriate Regional Office by November 1.
1980.
Sincerely,
