Attachment 1 to GNRO-2015/00008 Response to Request For Additional Information to GNRO-2015/00008 Page 1 of 2 Grand Gulf Nuclear Station's Responses to Request For Additional Information as received via phone call with the Nuclear Regulatory Commission Project Manager on Tuesday, January 20, 2015.

Item 1)

On Page 3.3-80, Should the line containing "cell containing one or more fuel assemblies" have been indented?

A review of this clean page contained in the submittal and the current page of the Grand Gulf Nuclear Station (GGNS) Technical Specification confirmed this line should have been indented.

The revised page is contained in Attachment 2 of GNRO-2015/00008.

Item 2)

Part A)

Page 3.6-31, Should numbering for the Required Action be C or C.1?

The number should be C.1. A review the clean page, as submitted in GGNS Letter GNRO-2013/00065 found that the number convention used in Required Action C.1 is correct and the Required Action is numbered C.1.

No follow-up actions are warranted.

Part B)

Page 3.6-31, Condition '0' was added. This new condition contains the following wording: "of condition C not met". Is this just for clarification?

Yes. The intent is to ensure that the user understand which required action was not met.

No follow-up actions are warranted.

Item 3)

Page 3.7-7, Verify the note inserted at Required Action C.1 is correct since Mode 3 is no longer part of the TS?

Yes MODE 3 is applicable to this TS and the note is applicable as requested.

No follow-up actions are warranted.

Item 4)

Page 3.7-3, Should "OR" be underlined, or not?

Yes the "OR" statements should be underlined. A review of the clean page, as submitted in GGNS Letter GNRO-2013/00065, found the "OR" statements are underlined in Condition "F."

No follow-up actions are warranted.

to GNRO-2015/00008 Page 2 of 2 Item 5)

Page 3.7-8, Was the 24 MFC LAR already approved? The 24 MFC LAR was amendment 197. Do we need the change (18 to 24 months) or has it already been approved?

We concur that the requested FREQUENCY change requested for Surveillance Requirement (SR) 3.7.3.3 was addressed by the issuance and implementation of License Amendment 197 and this request change is no longer needed.

The revised page is contained in Attachment 2 of GNRO-2015/00008.

Item 6)

Page 3.7-9, Should the symbol used be a "degrees" symbol?

Yes, this is a degree symbol. A review of the clean page, as submitted in GGNS Letter GNRO-2013/00065, found that the degree symbol is correctly inserted in Required Action B.1.

No follow-up actions are warranted.

Item 7)

Part A)

Page 3.8-4 Action D, Should it be "Systems C Operating" or "Systems-Operating"?

Yes, it should be "Systems-operating".

No follow-up actions are warranted.

Part B)

Page 3.8-4 Action G, Shouldn't the 36 hours4.166667e-4 days <br />0.01 hours <br />5.952381e-5 weeks <br />1.3698e-5 months <br /> be deleted?
