It appears that the above violation was due to a' weakness in implementing your design

review process with regard to facility change requests. The facility change requests were

implemented without adequately reviewing the existing design parameters. This resulted in .

,

changing an important setpoint of the loss of coolant incident (LOCI) sequencer timer, which

>

was previously corrected during the EDSF1 inspection to prevent the overloading of the

emergency diesel generators.

t

!

In addition, the corrective actions for five previously identified issues were found to be

adequate and the items are closed. Your interim corrective actions pertaining to 'he

j

ventilation sys'.em were found to be adequate. However, additional long-term corrective

j

actions, as committed in your previous responses, require further NRC review; therefore,

,

this item is updated in this report and remains open.

Your cooperation with us in this matter is appreciated.
