DRAFT RAI for the WBN1 exigent amendment (MF6286)

Mr. Arent and Mr. Bryan, In addition to the clarification sent earlier today, the NRC staff has reviewed the LRA for the exigent amendment for Watts Bar Nuclear Plant, Unit 1 submitted May 29, 2015 related to the RCS hot leg temperature and has the following DRAFT request for additional information:

1) The Auxiliary Control Room would be needed in the event that a fire in the Control Building challenges operator control from the Main Control Room. Describe any enhancements or additional fire protection features that will be implemented in the Control Building for the duration of this technical specification revision to compensate for the reduction in safe shutdown monitoring. For example, describe any additional or enhanced compensatory measures that may be appropriate for out of service fire protection systems, additional limitations that may be appropriate for hot work in the Control Building, or a higher level of monitoring for transient combustibles in the Control Building.

2) Describe any enhanced or additional compensatory measures planned in the event that any other indication becomes unavailable in the Auxiliary Control Room during this period.

If TVA would like to have a call to clarify this DRAFT request for information let me know and I will set up a teleconference.
