Technical Specification 6.8.1.a recuires that written procedures be established, implemented, and mainta ned as recommended in Appendix "A" of Regulatory Guide 1.33 Revision 2, February 1978.
Section 9.a of Appendix "A" of Regulatory Gufde 1.33 recommends that maintenance that can effect the 3erformance of safety-related equipment be performed in accordance with wr tten procedures, documented instructions, or drawings appropriate to the circumstances.
Contrary to the above on April 10, 1988, plant personnel backfilled the instrument reference Ieg for Unit I reactor water level transmitters 1821-N000C and 1821-N0800 without specific instructions or procedural guidance.
A full Reactor Protection System actuation occurred, and the Primary Containment Isolation System Group 2 outboard valves closed as a result of this backfilling operation.
Since Unit I was in cold shutdown at the time of this event, an actual scram did not occur.
This is a Severity Level IV violation (Supplement I).
B.
Unit 2 Technical Specification 3.6.1.1 requires that primary cor.tainment integrity be maintained while the unit is in Operational Conditions 1, 2, or 3.
Without primary containment integrity, primary containment integrity is required to be restored within 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> or the unit is required to be in at least Hot Shutdown within the next 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> and in Cold Shutdown within the following 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />.
Contrary to the above, on April integrity was inadvertently violated for approximatel,y 1-315,1988, U containment functional testing of the
'A" Hydrogen Recombiner System while Unit 2 was in Operational Condition 1.
Containment isolation valves 2T49-F002A and 2T49-F004A were opened for functional testing before the integrity of system piping had been demonstrated.
A portion of the system's piping had previously been cut and welded to remove an obstruction.
This is a Severity Level IV violation (Supplement I).
