Enclosure 1
Summary of Issues Discussed During Meeting on October 3, 1985 Concerning Power Systems Issues for NMP-2 SER Issues 1.
Separation Criteria (open item 11)
Prior to the meeting the l(RC selected four sample packages to be discussed at the meeting.
These sample packages were selected from the list of items for which analysis was performed by GE to justify adequate separation.
The four packages chosen were:
a) a WATT/Kr. meter b) a WATT transducer c) a transducer d) a controller The ViRC expressed concern that for all non-Class 1E components the analysis should assume these items will fail.
The applicant stated that they understood that the analysis was performed in this manner.
- However, a cursory inspection by the NRC staff revealed that all failure modes had not been considered for non-Class 1E components.
Consequently the applicant was requested to review all packages for which analysis was used to justify separation to properly consider failure of the non-Class 1E devices.
The staff suggested the applicant review work done for Fermi-2 in this area.
By letter dated October 9, 1985 the applicant committed to do this.
