A.
10 CFR 50, Appendix B, Criterion III, states, in part, that,
" Measures shall be established to assure that applicable regulatory requirements and the design basis...are correctly
'ranslated into... drawings.... "
Paragraph 17.1.3 of the Quality Assurance Program documented in the PSAR states, in part, that, " Prior to submittal of design documents to either WFPSS or Ebasco for review and/or approval, the design contractors, including Ebasco, are responsible for verify;ng that the design meets the requirements of the specifications..."
Contract specification No. 3240-95 (entitled, Structural Steel -
Phase I") specifies that the design 'for structural steel shall be in accordance with project specification No. 3240-448 (entitled
" Structural Steel"). Specification No. 3240-448, paragraph 2.6 states, in part, that, " Field connections shall be friction type joints..." and that connections shal1 ~ be in 'accordance with specification No. 3240-50lWa (sntitled "High Strength Bolted Field Connections for Structural Steel"). Specification
'No. 3240-50lWa, paragraph 6 states, in part, that, " Joints shall be friction-type bolted connections detailed for an allowable working stress in shear of 15,000 psi...."
Contrary to the above, on September 29, 1980, the steel fabricator's design drawings for structural steel beam connections, detailed joint configurations which exceeded the 15,000 psi bolt stress limit of specification 50lWa (Fought drawings Nos.
40,-41, 44, 48, 49, 206,'207, 248, 304, 341, 343, and 350) and
.specified the use of beariag type joints, with accompanying shear stresses of 29,200 to 31,900 psi (Fought drawings Nos.
40,41,and44).
Furthermore, the installing contractor's cuality(program did not address the inspection of bearing type joints i.e...no bolt threads in the shear planes).
This is a Severity Level 4 violation (Supplement II).

This instruction requires. tnat bolting be tightened.
Contrary to the acove, en October 22, 1980, the high strength bolts were loose in the structural joints joining beams 295 B to 293 5 and 219 F/292 E to 39 A at the 362.5 foot elevation in the Unit 5 reactor auxiliary building. These joints had been.inscected and accepted on July 19, 1980 and Septemoer 10, -
