FW: Clarification question for the WBN1 exigent amendment (MF6286)

Mr. Arent and Mr. Bryan, I am filling in for Jeanne this week and working on the exigent amendment for Watts Bar Unit 1 related to the RCS hot leg temperature. The NRC staff would like clarification on the following information contained in the application:

TVA submitted the exigent amendment request by their letter number CNL-15-108, dated May 29, 2015 for WBN1. On the second page of the cover letter TVA stated, The problem has been isolated to components (modifier circuit or thermocouple) both located inside the Reactor Building Polar Crane Wall. The term modifier circuit is a non-specific term and its usage does not clarify its function. Please clarify the nature and function of this modifier circuit.

It is likely most efficient to have a call as soon as possible to discuss this item. Please let me know when TVA can support a call and I will get one scheduled. If you have any questions please let me know.
