MEETING

SUMMARY

- JULY 22, 1988 MEETING TO DISCUSS NRC BULLETIN 88-05 DEALING WITH NON-CONFORMING MATERIALS On July 22, 1988, NUMARC met with the NRC to discuss Bulletin 88-05 which deals with non-conforming material. A list of attendees is given in Hand-outs provided by NUMARC are included in Enclosure 2.

NUMARC first presented the results of the testing of the suspect material. To date, about sixty laboratory tests have been conducted and all indicate ultimate tensile strengths above 66.8 XSI, with 90% above 70 XSI. Field hardness tests, using an instrument manufactured by Equotip, have been conducted on over 1300 pieces. The distribution of the results is similar to that of the laboratory tests. More than 95% of the pieces demonstrate ultimate tensile strengths above the minimum of 70 KSI. The only items with values significantly below 70 XSI are blind flanges, which have been demonstrated by analysis to be acceptable for service at tensile strengths below any of the test results. NUMARC then discussed the details of its generic analysis which demonstrates that the suspect material will perform its intended function even if its tensile strength is as low as 40 XSI. Based on the results of the testing and analysis, NUMARC concluded that the suspect material presents a minimal safety concern. NUMARC recommended that the staff temporarily suspend the requirements of Bulletin 88-05, and its Supplement 1, to avoid the significant effort which would be expended while the available information is being assessed. NUMARC estimated that approximately 100 man-years per month are being expended by the industry to satisfy the bulletin. NUMARC comitted to provide a letter within several days recomending this temporary suspension. The NRC staff promised a prompt reply to NUMARC's suggestion: L.

Evaluate material with UTS values bet. 40 & 69 KSI. Provide ready reference material for use by utilities in evaluating short term and long term suitability for service COMPONENTS COVERED ANSI B16.11 Fittings Socket welded and threaded couplings and half couplings Common press, ratings and matchpup with pipe size & sch ANSI B16.5 Blind Flanges All sizes ANSI B16.5 Flanges

GENERIC ANALYSIS REPORT ~ BASIS Complies with applicable code and ANSI B16. design rule with allowables of substrength material adjusted downward FlTTINGS Pressure design Uses Eq. 3 of NC-3641 Applies to all plants regardless of vintage More conservative than derated ANSI B16.11 pressures Moment Design Evaluation method applies to all design equations Automatically applies to all code effective dates BLIND FLANGES Uses derated pressures from ANSI B16.5 standard WELDED FLANGES PRESSURE DESIGN Same as blind flanges Moment Design - Uses design rules of NC-3658 of the 1979 summer addenda of Section ill Code, which is permissible for all plants regardless of vintage. - Provides generic qual. using conservative assumptions, or provides allowable moment loads for specific evaluations July 22,1988

~ 'th ~ 07/21/1988 SOCKET WELDED AND THREADED FITTINGS APPROACH o Pressu're Design Maximum design pressures are used to determine the required allowable stresses of the fitting material based on Equation (3) of ASME Section !!! NC-3641. If the Su values determined from testing are equal to or greater than the minimum required by the table, the fitting is acceptable, o Moment Loading Qualification Piping to flange moment capacity ratio are calculated as follows: (/,)(2,)60 Ratio (max. ratio to allowable limits) (/,)(2,)S. where I. - SIF for fitting; I = SIF for weld joint; p Z, = section modulus of fitting; Z, = section modulus of pipe; Fittings are generically qualified when their ratios are equal to or less than l 1.0. Fittings with ratios above 1.0 require plant unique evaluations to qualify for long term service using moments frcm the system design calculations. 1 e l t l l 1 l s

(2) Welded flanges generically qualify for rceent loading if the stated yield stress ratio is < or = 1.3. field stess ratio is defined as the ratio of the yield stress required to satisfy equation 12 of NC 3658.1, using nonents calculated per note (1) above (Syr), to the suspect s.sterial yield stress of 28 Ksl = Syr/28. (3) Table C2 calculates the required yletd stress ratios for suspect materlat with a yield stress of 28 Ksi and a tensite stress of 56 Ksi. For suspect materlat with higher su than 56 Ksi, multiply the stated ratios by the factor 56/Sv. (4) " Denotes Sy ratio exceeds mity. Plant specific evaluation required.
