Overall N/A 2/0 2/0 2.0 GENERIC STRENGTilS The candidates performed well. Recognition and diagnosis of malfunctions was in most instances extremely rapid. Actions required by procedures were carried out in a timely fashion. Mitigating actions not explicitly required by procedures in effect, but appropriate for the specific event, were also recommended to supervisory personnel. An example of this was a recommendation by the primary operator in the second scenario to dispatch an auxiliary operator to reset a tripped breaker for a PORV bkxk valve, thus allowing the loss of inventory during a stuck PORV loss of coolant to be terminated. Coordination between the primary and secondary operators was effective.
3.0 WEAKNESSES OBSERVED There were minor deficiencies in communications. In some instances, gestures and head nods were used to acknowledge orders instead of verbal repeatbacks. Verbal communications.
tended to be quiet and sometimes difficult to hear.

In the scenario involving the failed open PORV, the primary operator took 4 minutes to notice this failure. Although this is not an excessive amount of time, it is considered a weakness since safety injection had initiated on low pressurizer pressure, the candidate reported RCS pressure low, and the candidate had looked at that section of the control board several time before realizing the PORV was open.

SIMULATION FACILITY REPORT
FACILITY LICENSEE: North Atlantic Energy Service Corporation
.
FACILITY DOCKET NO.: 50-443 l
Operating Tests administered on 12/15, IP92 This form is to be used only to report observations. These observations do not constitute audit or inspection findings and are not, without further verification and review, indicative of
+
non-compliance with 10 CFR 55.45(b). These observations do not affect NRC certification or approval of the simulation facility _other than to provide information which may be used in future evaluations. No licerr.,ec action is required in response to these observations.
The following simulator deficiency was observed:
The initial condition for one scenario started with the main generator ready for synchronization. During scenario validation, the facility staff was unable to close the generator output breaker. This required a modification of the scenario such that the starting point was just after generator synch. This affected the exam in that the
-
examiners were unable to observe the candidate control SG levels manually in response to the initial load p]ckup following main generator synchronization.
