ATTACHMENT Statements of Additional Information Regarding. Management' Actions'Taken Following the Natural. Circulation Tests 1.,The Chronology of Communications provided in' Appendix-B .

to the Augmented Inspection Team (AIT) Report states' -

that atL1:00 PM on June 22,.1989, licensee' management

' set a tentative schedule for restart on the morning of June 123.

-It is important that it be. recognized that the tenta-tive restart schedule'which was established at that time was for1the: sole. purpose of insuring that the numerous' personnel.which would be required to, perform and observe'the' Natural Circulation Test would be

~

available if the plant conditions were ready to conduct.

the-test. In support of the above, it was emphasized during the 1:00 PM management meeting on June 22 that there was no intent to restart the reactor until a thorough assessment of the event was complete and the NRC was in' agreement with that assessment. It was also stated by' myself at the same meeting that restart of the reactor for performance of the test would be subject to the following conditions:

1). the post-trip assessment was complete,

' :2 ) . any corrective actions identified in the post-trip assessment as " required for-restart" were complete, and 3). a management decision was made to restart the reactor and repeat the test.

j.

These conditions for restart were also stated durang the 6:00 PM conference call with the NRC Region I Branch Chief on June 22.

i 2..The~ Chronology.of Communication provided in Appendix'B to'the AIT Report states that at 2:00 PM on June 22, 1989, the licensee's' Incident Investigation Team, Post-Trip.

Review Team and Self-Assessment Team were established.

Although not mentioned in the Report,11t should be noted~that, in addition to the above-mentioned activities,'

interviews were, initiated.with the operators who were on-shift during the test to determine why they did not' trip the reactor in accordance with the 1-ST-22 test

' criteria. The results of;these' interviews were discussed

'in detail at the 4:30 PM management meeting. The preliminary conclusions which were reached at that meeting with regard to: operator actions were very.similar to the conclusions reached by the AIT in Report Section 5.1.4 and the~ corresponding portions of. Report Section 2.2.

These preliminary conclusions provided the basis for the discussion of operator response with the Region I -

Branch Chief during the 6:00 PM conference call on June 22.
