MEMORANDUM T0: William J. McNulty, Director Office of Investigations f i\} d J FROM: Albert F. Gibson, Director f )

Division of Reactor Safety 7 SUBJECT: VIOLATIONS OF PROCEDURES CONCERNING MAKEUP TANK PRESSURE AT CRYSTAL RIVER NUCLEAR PLANT Our inspection, conducted December 11-15, 1995, has determined that operators apparently violated procedures on September 4,1994. Excerpts from draft inspection Report 50-302/95-22 are included belo On September 4,1994, Operators did not follow OP-402 instructions for adding hydrogen by manually bypassing the 15 psig hydrogen regulator. The applicable step in OP< 102 specifically required " ensuring MUT pressure limit is not exceeded." However, operators exceeded the Curve 8 MUT pressure limit during hydrogen addition. Operators also exceeded the administrative limits of OP-103B, Curve 8, for an extended period of time (about 43 minutes). In addition, during this evolution, operators did not take timely action in response to the " MAKEUP TANK PRESS HIGH" annunciator. Instead of reducing pressure to clear the alarm as required, operators reduced level (and pressure) which caured the Curve 8 limits to be exceeded by an increasing amount. Operators left the alarm in for about 43 minutes before venting the make-up tank to clear the alarm. This is an example of apparent violation 50-302/95-13-0 i l
