2.0 Analog Transmitter Trip System (ATTS) Modification

2.1 The installation of the FitzPatrick ATTS modification is in 4 accordance with General Electric's Licensing Topical Report NEDO-21617-A, Class 1 and noted in the NRC letter MFN279-78 dated June 17, 1978, as acceptable for reference in license application .2 The purpose of the ATTS modification is to improve sensor accuracy and reliability; reduce the time that the Reactor Protection System (RPS) logic must be in half scram condition; reduce calibration frequency; and reduce personnel exposure to radiatio .3 The modification consists of replacement of the mechanical switches with an analog system capable of more accurately monitoring Emergency Core Cooling System (ECCS) and the Reactor Protection System (RPS)

protection parameters. The analog instruments provide inputs to processing cabinets for conversion to corresponding digital signal,

'

, Additional changes include nuclear qualified class 1E transmitters and RTD's associated with the Leak Detection System in the Steam Tunnel, Personnel Access, Torus, Residual Heat Removal (RHR) Heat Exchanger and Crescent Area. The new transmitters and RTD's are

'

routed through ATTS cabinets 9-91, 9-92, 9-93, 9-94, 9-95, and 9-9 The cabinets are located in the control building relay room and provide output contacts to the main control room annunciator syste . .-- - , -_ -.- ..--. -.. -- __- -, - -- _

Cabinets used for ECCS (9-95 & 9-96) receive power from appropriate Divisional Essential AC and DC distribution systems. RPS cabinets (9-91, 9-92, 9-93, & 9-94) receive power from appropriate 120 vac RPS .

) New cables, raceways and terminal boxes for the instrument loops have been added. Separation on the instrument racks between instruments and terminal boxes is provided through the use of condui Terminal strips in the terminal boxes have been replaced with cable splices using the Raychem splice. However, the length of the splice seal is only 1 inch verses the qualified Raychem splice seal length of 2 inches. Maintenance Procedure MP-71.1, Section 7.4 references the use of the Raychem Procedures for splicing low voltage jacketed cable. Section 7.4.2 of this procedure states, in part; " Install the

'

Raychc= WCSF type splice sleeve in accordance with Appendix A7 Appendix A instructions requires that Raychem sleeve has minimum of

, 2 inches seal area at each end of splice. Engineering Change Request

with an environmentally qualified splice per its splice detail in Appendixes F, G, H, J, I, & H. However, the splice detail illustrated only has a 1 inch seal area at each end. Test data qualifying the splice detail of ECR-119 was not available.

2.4 This item is unresolved pending NRC review of (1) licensee clarf f t -

cation of conflicting instructions regarding implementation of cable i

splices as noted in MP-71.1 and ECR-119 and (2) engineering justification and environmental qualifications for using Raychem splice having a 1 inch seal length. (333/85-16-01)

The maximum pull tension was not evident on the cable pull ticket. Discussions with the licensee indicates that all ATTS modification cable pulls were done by hand, using three craftsme .4 In addition, Section 4.14 of the cable Pull Procedure No. CMP 9.3-3.76 states, in part, that: " Cable pull tickets give maximum tensile strength. Engineer to provide instructions on use of above for pulling groups of cable."

The licensee was unable to provide the basis for determining that three craf tsmen were adequate for the cable pulling function or that the maximum pull tension was not exceeded by using the three craftsme .5 This item is unresolved pending NRC review of licensee documentation on maximum pull tension for installed ATTS cable and assurance that maximum pull tension was not exceeded for the smallest cables in the grou (333/85-16-02)
