Potential Problem Specification 13-FM-209, Section 4.3.1.2, requires supports to be fabricated to ASME Section III, Subsection NF.
ASME Section III, Subsection NF, Paragraph 4724, requires bolts tightened by means of a calibrated torque wrench shall be installed with a hardened washer under the nut or head, whichever is the element turned in tightening.
Bechtel Supplier Quality Representative noted during surveillance inspection activities that supplier, ITT Grinnell, Warren, Ohio, was installing mild carbon steel washers under the bolt heads on Sizes 1, 3 and 10 mechanical shock suppressors (Figure 306, Pivot Mount, and Figure 307, Extension Assemblies).
On Sizes k and Figures 306 and 307 Shocks, the supplier had installed hardened brass washers.
II.
Approach To and Status Of Proposed Resolution Bechtel has been notified by Code Interpretation N1 81-163 (copy attached) that NF-4724 permits the use of hardened brass washers.
The Ballot Vote for the Code Case which is expected to authorize that mild steel washers may be used as an alternative to the hardened washers required by NF-4724, is scheduled for April, 1982.
- III, Projected Completion of Corrective Action and Submittal of the Final Report The evaluation and final report are forecast to be completed by June 4, 1982.
