Contrary to the above, on September'16, 1996,Section XI inservice i

testing procedures for the emergency diesel generator starting air receiver pressure relieving devices were inadequate in that setpoints were set in the range of 340 360 psig which was more than 10% above the

[

maximum allowable working pressure of 300 psig.

j.

This is a Severity Level IV Violation (Supplement I).

B.

Technical S)ecification 6.8.1.a requires, in part, that procedures shall be establisled, implemented, and maintained covering the activities recommended in Appendix A of Regulatory Guide 1.33, Revision 2.
