Dear Sir or Madam:

Entergy Operations, Inc. is providing, in the Attachment, Grand Gulf Nuclear Station Operation's personnel training results on the three MELLLA+ time-critical operator actions as committed in Reference 1.

On August 31,2015, the NRC issued the referenced amendment. Facility Operating License Condition #49 requires the results of the three MELLLA+ time critical operator actions (TCOA) training to be reported to the NRC Project Manager within 60 days of completion of the training.

The Operating License Condition reads as follows:

Prior to Operation in the MELLLA+ Domain, Entergy will:

Train all active operating crews to perform the following three MELLLA+ time-critical operator actions:

1. Initiate Reactor Water Level Reduction (90 seconds following failure to scram concurrent with no reactor recirculation pumps in service and CTP> 5%).
2. Initiate Standby Liquid Control Injection (300 seconds if CTP> 5% or before Suppression Pool Temperature reaches 110 degrees F).
3. Initiate Residual Heat Removal Suppression Pool Cooling (660 seconds).

GGNS will validate that all active operating crews have met the time requirements for the three MELLLA+ time-critical operator actions during evaluated scenarios.

GGNS will report any MELLLA+ time-critical actions that are converted to "immediate actions" to the NRC Project Manager.

The following are one-time actions which expire after the first report:

The results of the three MELLLA+ time-critical operator actions training will be reported to the NRC Project Manager within 60 days of completion of the training.

The reported results will include the full range of response times for each time-critical action and the average times for each crew.

Any MELLLA+ time-critical operator training failures during evaluated scenarios will be reported to the NRC within 60 days of any failures with a plan for resolution.

On February 11, 2016, Grand Gulf Nuclear Station Operation's personnel completed the required TCOA training. Results of the three MELLLA+ time-critical operator actions training are attached.

Grand Gulf Nuclear Station has made the second TCOA (initiate standby liquid control injection) an immediate operator action.

This letter contains no new commitments. If you have any questions or require additional information, please contact James Nadeau at 601-437-2103.

I declare under penalty of perjury that the foregoing is true and correct. Executed on the 2nd day of March, 2016.

Sincerely,

-v.-__:----_-.... __

  • *Crew scenario run with the normal crew lineup. Teams evaluated with an "as left" simulator evaluation.
  • The individual times were evaluated using a 3 man crew with 1 SRO and 2 RO's. Completion times were measured for each TCOA for each person. Then RO positions were swapped and run again with a different CRS to allow efficient evaluation of all crew members. SRO's evaluated as the CRS (Control Room Supervisor), directing actions as appropriate and setting correct priorities.
  • RO's evaluated twice, both as the ATC (At the Controls Operator) and CRO (Control Room Operator).
  • All Evaluations conducted with worst case scenario of operation:
  • 100% Reactor Power, Operating in the MELLLA Plus Domain
  • No Other Malfunctions
