A.
10 CFR 50, Appendix B, Criterion V as implemented by TVA Topical Report TVA TR 75-01 paragraph 17.2.5 requires activities affecting quality be accomplished in accordance with procedures.
TVA Process Specification 1.C. 1.2.(b),
dated 2/1/81, paragraph 9.8 and
- 15. 1 require welders to remove arc strikes and slag from welds and adjacent base material.
TVA Process Specification 3.M.5. 1.(d),
dated 3/21/79, paragraph B. 1 requires welding inspectors to assure. that all welds and adjacent base material are free of arc strikes, weld spatter and slag.
Paragraph B.O of 3.H.5. 1.(d) requires welding inspectors to inspect all applicable welds for compliance to drawing weld size requirements.
Contrary to the above, on June 24, 1981, activities affecting quality were not accomplished in accordance with procedures in that the following were noted on completed and accepted welds on torus modification catwalk knee braces:
Numerous arc strikes A large amount of weld spatter Several welds with adhering slag The reinforcing fillet on a groove weld was approximately 1/16-inch undersized This is a Severity Level V Violation (Supplement I.E).
B..
10 CFR 50, Appendix B, Criterion IX as implemented by TYA Topical Report TVA 01 paragraph 17.2.9 requires measures be established to assure special processes, including nondestructive testing are controlled.
TVA procedure NPT-NC-l, Revision 1 paragraph 4.2 requires masking material be removed prior to liquid penetrant (PT) application.
TVA procedure NPT-1, the applicable penetrant procedure for inservice inspection, requires that any indication believed to be non-relevant be regarded as a defect and re-examined to determine whether defects are present and that linear indi-cations greater than 1/16" in length be rejected.
Contrary to the above, on June 24,

components (including supports)...shall meet the requirements set forth in Section XI of editions of the ASME Boiler and Pressure Vessel Code".
Section XI of the ASME Boiler and Pressure Vessel Code requires that sup-port settings of constant and variable spring type hanger s, snubbers and shock absorbers be inspected and verified.
Contrary to the
- above, ASME Section XI requirements have not been met in that for inspections performed on spring type hangers,
- snubbers, and shock absorbers during previous outages and the current outage, support settings were not inspected and/or verified.
This is a Severity Level V Violation (Supplement I.E).
