Initial Assessment of Significance: There appears to be sufficient specificity to warrant followup of each of these allegations. Initial disposition was made in IR 81-12 for AQC-10. Coatings concerns in AQO-5 may be discussed in Brookhaven National Lab Report. Source: QA/QC Category 18 - Undocumented Activity / Rework Approach to Resolution: 1. Review the May 1984 BNL interim report. If the second BNL report is available, this report should be reviewed in-depth. Determine if adequate documentation is available to support BNL report (s). Take appropriate action to close allegations. 2. Review licensee's 3 documents entitled: TUGC CPSES " Analysis of the Clogging of ECCS Sump Trash Racks by Debris and Paint Peels Following Accident"; "Model Testing of the Recirculation Containment. Sump"; and " Evaluation of Paint and Insulation Debris Effects.on Containment Emergency Sump Performance." 3. Review IR 81-12 to determine if documentation adequately supports findings of AQC-10. If documentation does not support findings, take appropriate action to close allegations. 4. Review repair, installation, welding, and documentation procedures, codes / standards, repair and documentation requirements, NRC requirements, and licensee commitments for adequacy at time work was performed; were codes / standards, FSAR, contractor requirements, and other commitments met? 5. Discuss adequacy of repair installation, and documentation procedures with personnel involved with these activities. Discuss adequacy of other - related procedures. Examine installation repair, documentation and authorization requirements, as appropriate, that are associated with any inadequate procedures identified during interviews. 6. Review sample of similar-types of procedures for adequacy. 7. Refer any examples of wrongdoing or significant defir.iencies to TRT manager. 8. Evaluate allegations for generic / safety implications. 9. Report on results of review / evaluation of allegations. Related Ocen Issues -, P 1.

suam op. Ot5CU15lON, DEC$lONS MO CDertmen5. W.1. Vogelsang discussed the AMP memo dated September 2,1981'in which Mr. b+ B. Eister had indicated a 60* bend without reannealing was acceptable. It was discussed that with some suppliers at CPSES (GE Co in particular) that it was necessary to bend terminals for internal wiring up to 120*. It was ~ pointed out that for these cases, the application was for short jumpers (normally under 18 inches), and as such, the full mechanical strength of
the connector was not required. ~ Floyd Renshaw responded that the current AMP position was that the subject teiminals could be bent one time to a 90* bend or two times to a 45* bend. . However, this does not preclude. bending the terminals up to 120*. In this ~ case, an Engineering evaluation for the specific type of application could
- be done by the product user. Items that should be taken into account are
as follows- a) length of wire to be supported by the terminal
b) the susceptibility to vibrations c) once installed if it is contemplated rebending these tenninals, , they should be discarded.and replaced by a new terminal. , - Floyd Renshaw also advised that while a terminal bent more that 90' to 120' would not retain its full' mechanical strength it would mainatin its . electrical characteristi.c, s. - .. . . , _ ~ GIV:dw' ..( .I'., - . ,'E:., -
