Materials & Metallurgy Mtg Minutes June 20, 1989 Actions Agreements and Commitments The Subcommittee agreed to have the Staff give a brief presentation on low apper shelf energy to the Committee at the July 13-15, 1989 meeting.
A Connittee letter wcs not recommended at this time.
Discussion In his opening remarks, P. Shewmon indicated that this issue had been around for a long time and had been resolved hypothetically in different situations. He expressed his understanding that the pressure vessels in question were made by B&W, were located in B&W and Westinghouse reactors and were welded with Linde 80 flux and copper coated weld wire. He also asked that the Staff address the current status of surveillance packages for these vessels.
M. Mayfield (RES) presented an overview of the Low Upper Shelf Vessel Research Program. He reviewed the fracture toughness requirements as given in 10 CFR 50, Appendix G.
Part of this requirement is that the upper shelf energy thioughout the life of the vessel must be maintained at no less than 50 ft-lbs (68J), unless justified in a manner approved by the Director, NRR. He indicated that there are currently 6 operating plants with an upper shelf energy of less than 50 ft-lbs. (by NRC Staff calculations) and only one of these has submitted written justification for continued operation. He outlined a four part research program which j
was intended to produce fully validated procedures for the 10 CFR 50, Appendix G uppt r shelf analyses. The four elements were:
Irradiation Damage, Analysis, Material Properties and Large-Scale Validation. He I
indicated that a large vessel specimen for some of these studies had been obtained from the pressure vessel intended for the abandoned l
Midland plant.

3 Materials & Metallurgy Mtg Minutes June 20, 1989 prepare for RES as in overview for NRC management. Copies of the draft-paper were obtained for Subcommittee Members and Consultants. The-problem of low apper shelf welds in some domestic PWR vessels was stated to have occurred in.the time frame from 1965 to 1973 because of the choice by B&W of materials used in the submerged art welding process.
l The subject welds had rather low initial Charpy upper shelf energies because'of the flux used wtich was Linde 80. He discussed the require-ments for reactor pressure vessels found in the 1965 version of Section III of the ASME code. No upper shelf energy requirements were listed.
He discussed the activities of the ASME Section XI committees and the NRC for resolution of USI A-11, as well as RG 1.99 and Order No. 744.
He described the development of the various analytical procedures from the J-T method in 1980, thru the R-Curves phase to the current J /U D M
. studies.
I E. Hackett (DTRC) and J. Joyce (USNA) disc.ussed their program to examine J /J resistance curves and their participation in an NRC established D g Working Group to investigate size / geometry issues on J IU R-Curves, to D M provide recommendations to NRC/ASME as to appropriate action regarding extension of R-Curve validity limits and method for extrapolating R-Curve data. They discussed the features, advantages, limitations and applications of the J integral analysis. They presented the test data from their original experimental program, blunt notch tests, engineering singularity limit analysis and a study of the OMEGA criteria. They dis-cussed the J IU controversy and indicated that resolution of "which J" D M required tearing instability experiments and analysis.
W. Corwin (ORNL) discussed the low upper shelf irradiation damage investigations in the HSST program at Oak Ridge. A series of 10 tests had been planned: b tests are completed,1 test has the irradiation phase completed, and 3 tests are still in the planning stage. Two of 1

the completed tests examined commercially fabricated Linde 80 welds.
One test series studied the fracttre toughness of state-of-the-art welds'.
Corwin further discussed the embrittling mechanisms in ferritic steels. attributed to a number of factors, such as, copper-rich l
clusters / precipitates, nickel in the presence of copper, phosphorus in low copper alloys, and matrix composition. The three test series in the planning stage will provide enhanced ductile fracture information, refined dato for predicting the shift in the transition toughness, and the basis for evaluating annealing effects on fracture toughness and ductile tearing.
H. Etherington'(ACRS) briefly discussed his concerns regarding the Charpy energy vs temperature curves to be used for low shelf material as well as high shelf. He presented some sketches to make his point. He urged the Staff to take a look at real data from B&W or Westinghouse l
irradiation curves and determine what numbers should be used for Ky values. They later explained to him how they believed they had done what he asked.
I W. Pennell (ORNL) discussed the large scale testing of low upper shelf material. He indicated that testing thick-walled vessels under combined pressure and thermal loading has provided a basis for evaluating cleav-l age crack arrest and ductile tearing in this material.
Four tests were l
planned for this program, two have been completed and the other two will be completed in FY 90 and FY 91. The two completed tests addressed the effectiveness of warm prestressing and the arrest of crack propagation in the ductile shelf. Both test gave results that were inconsistent with J-R Curve analysis of stable taarir9 The fourth test should provide data on brittle-ductile flaw propagation in low upper shelf material with prototypic tensile strength.
N. Randall (RES) presented a chronology of the regulatory approach to low upper shelf materials in reactor vessels and discussed proposed l
(:

criteria for flaw evaluation. He presented a sketch to illustrate J-R curves, some that meet the proposed criteria and some that don't.
L
' P. Shewmon asked about the confidence one would get from applying NDE techniques for flaw detection to the weld areas in the ten-year service
- inspection. The Staff was not too optimistic about these examinations.
E. Hackett (DTRC) cited an example regarding a submarine hull plate that.
had a two-inch flaw through 80% of the plate thickness. This flaw was not detected through 10 applied NDE tests but was fcund during the final.
painting process.
The meeting concluded with a planning session to prepare a presentation for the Committee during the July 13-15, 1989 meeting.
