Clarification Questions on ET 13-0035, dated 11/21/13 (FPP - Alt SD Capability; TAC No. MF3112)
Steve, the AFPB staff reviewing the submittal need some minor clarifications on the submittal (ADAMS Accession No. ML13331A728). They look simple, but we dont want to assume.
The bottom paragraph on Att. I, page 14/64, refers to one cable carrying the temperature signal for all 4 transmitters per loop to the protection cabinet, but the top paragraph of page 15/64 refers to two cables (one per train) carrying the result from each protection cabinet to each SSPS cabinet.
Both paragraphs have the following sentence, The average temperature of each loop is calculated within the protection cabinet and the output is sent to both trains of SSPS input cabinets.
Although worded slightly different they both refer to SSPS input cabinets (SB029A - Train A and SB032A - Train B).
Its not clear what loop goes to what train.
Signals for Train A (Loops 2 and 3) enter protection cabinets SB037 (Loop 3) and SB038 (Loop 1) through the lower cable spreading room. There are no exposed cables in the equipment cabinet area associated with the Train A input signals except those within the cabinets. Signals for Train B (Loops 2 and 4) enter protection cabinets SB041 (Loop 4) and SB042 (Loop 2) from the upper cable spreading room via raceway that is installed within the equipment cabinet area of the control room.
What happened to Loop 1?
RCS temperature Loop 1 and Loop 3 signals are Train A signals that are processed to SSPS input cabinet SB029A (Train A). The green highlighted text above (Loops 2 and 3) should be (Loops 1 and 3).
2 In Att. I, page 62/64, the licensee references OFN RP-017, Revision 41, but in document E-F9915, page 4/102, the licensee references OFN RP-017, Revision 42. Please confirm the revision numbers.
The correct revision for the submitted license amendment request is Revision 42. Revision 42 was issued on 10/29/13 and Reference 4 in Attachment I to ET 13-0035 (pg 62 of 64) was not updated.
Thanks, Fred
