ENCLOSURE 2
NOTICE OF DEVIATION Florida Power and Light Company Turkey Point Units 3 and 4
Docket Nos.
50-250 and 50-251 License Nos.
DPR-31 and DPR-41 The following deviation was identified during a Nuclear Regulatory Commission (NRC) inspection conducted on April 3-6 and April 16-18, 1986.
A Confirmation of Action letter issued to FPL on April 2, 1986, confirmed that the total loads on emergency diesel generators would be reduced to no more than 2845 KW and that procedures would be changed to ensure operation within this limitation.
0 Contrary to the above, the licensee failed to adequately revise procedures to'ssure operation of the emergency diesel generators within load limitations, in that:
a.
Operating procedure 4-OP-006 was not revised to ensure that the Confirmation of Action letter specified emergency diesel generator load'imit of 2845 KW was not exceeded.
On April 14, 1986, this procedure was utilized to crosstie the 4B 480 volt load center to the 4A 480 volt load center without a safety evaluation to ensure that the
'onfirmation of Action letter load limit would not be exceeded for emergency diesel generator A under accident conditions.
The use of 4-OP-006 placed the plant in a condition outside. of the assumptions in a justification for continued operation contained in JPE-L-86-59, Revision I for the operation of Unit 3.
b.
Emergency Operating Procedure 3-ECA-0.0, Loss of All AC power, did not ensure that an RHR pump would be secured and a battery charger restored within 30 minutes to prevent overloading an emergency diesel generator (EDG) with a loss of all AC power on Unit 3.
Attachment E of ECA 0.0 also did not contain direction to ensure that in the one EDG available
- case, that the battery charger is restored utilizing the normal bypass switch.
Utilizing the "reset switch," which is the normal method of restoration, could potentially overload the EDG.
c ~
Attachment E of 3-EOP-E-O, Step 2, directed the operator to restart a
computer room chiller within one hour following a reactor trip and loss of offsite power.
Starting a computer chiller (59 KW) prior to securing a containment spray pump could potentially overload an EDG.
Specific precautions to ensure the computer room chillers were not restarted until after the containment spray pumps are secured were not contained in Attachment E of 3-EOP-E-O.
