EPRI M. Behravesh F. Annirato Y. Jeong R. Shankar R. Stone Highlights
- 1. S. Doctor, Pacific Northwest Laboratory, presented a status report on inspection reliability of cast stainless steel. He discussed 1)
PISC III - Centrifugally cast stainless steel round robin tests (CCSSRRT), 2) Post CCSSRRT studies, 3) PNL cast stainless steel studies, and 4) PISC III program.
The PISC III CCSSRRT - screening phase has been reported in NUREG/CR-4970, dated October 1987. In this phase 15 cast stainless l steel specimens were used; 11 contained thermal fatigue cracks, 4 l contained no intended cracks and that the weld crowns were ground l
j but not perfectly. The specimen contained equiaxed or columnar microstructure. Eighteen teams performed the inspections. The most common inspection procedural technique used was dual-probe, l longitudinal wave at 1 MHZ. The conclusions of the screening phase 1
l are as follows:
l o In general, inspection performance was rather poor. Some 1
I operator / technique combinations did show potential, other operators with the same procedure did poorly.
,,,or-
- Minutes / Metal Components Mtg. 3 Charlotte, NC, March 15, 1988 o High false call rates made it difficult to ambiguously analyze the results o .In general, false call probability (FCP) was higher in columnar thal equiaxed microstructure.
o Single-sided versus both side inspection effectiveness could not be resolved due to the high FCP in columnar material, o Two laboratory-type radiographic inspections had good results, but these are not adaptable for field inspections.
The post CCSSRRT study was performed at PNL. The data base was collect-ed with the SAFT system with a 500 k HZ shear-wave transducer. Results
'from this study indicated that 1) detections were probably based on signal amplitude, 2) no simple filter exists for both colunmar and equiaxed material to reject unwanted coherent grain scattered signals and 3) the problem is not totally one of signal-to-noise since spectrum of defects and noise are quite similar.
PNL also performed a coarse grained material inspection phase which was a planned task on NDE Reliability program. The objective was to evaluate the effectiveness of ultrasonic techniques for inspecting cast materials, understand the physics of the problem, assess methods to provide improvements for inspections, determine the limitations of solutions and recommend improvements to code / regulatory requirements.
The four problem areas being addressed were 1) far-side weld inspections, 2) cast stainless steel inspections, 3) dissimilar metal
- weld inspections and 4) weld overlay inspections The approach was to carefully map sound field transmission properties. A digital system was

- Charlotte, NC, March 15, 1988 required to separate the diffdrent modes resulting from scattering, mode conversions and beam skewing. Four cast microstructures are under study, 1) columnar, 2) equiaxed, 3) mixed modes and 4) layered structures. The status of this task are as follows:
[i o Completed L-wave attenuation measurements - naught degree o Completed L-wave field profiles - naught degree U
o In progress 45 L-wave field profiles.
Studies performed thus far concludes that microstructure is very impor-tant in UT inspection effectiveness and that more complicated micro-structures create greater inspection difficulties due to sound field distortion.
S. Doctor next discussed the planned PISC III - Action 4 round robin studies on austinetic steels (cast and wrought). Co-leaders for this study are S. Doctor, PNL and H. Herkenrath, ISPRA. The objectives of this program are as follows:
o identify procedures that have the potential to detect and size defects and to discriminate between flawed and unflawed materials, o complement the capability and reliability studies by evaluating the effect of important material and defect vari-ables, and

A large interest, here and abroad, in participating in this study has been shown. Testing is to start in the fall of 1988.
A. Curtis III, Rochester Gas & Electric, presented a brief overview of the Westinghouse Owners Group (WOG)/EPRI coordinated program on ultrasonic exanination of welded joints in centrifically cast stainless steel pipes of the PWR main coolant loops. He stated that studies have shown that the minimum ASME Section XI code exam is inadequate in detecting and sizing flaws in cast stainless steel pipes, and that E0G/EPRI initiated and supported a coordinated program that was started in 1984.
M. Behravesh, EPRI, presented a status report on the )L OG/EPRI program on ultrasonic examination of cast stainless steel piping welds. NDE findings and status thus far are as follows:
o There is a limited experience base with NDE of CCSS, but the situation is improving, o Variations in UT characteristics of CCSS limit the develop-ment / application of a fixed UT procedure for all plants.
Variations in UT characteristics are also found among differ-ent joints in the same plant and even along a single joint, i

o Proper reference material for calibration sensitivity is essential to the NDE of CCSS. An a priori knowledge of the materials UT characteristics is necessary for test parameter optimization.
o Depending on the material, detection sensitivities for de-tection of 10-40% through wall flaws can be demonstrated, o Five EPRI reports dealing with CCSS have been published. The document numbers and dates are as follows:
- EPRI NP-4996-LD, December 1986
- EPRI NP-5131, June 1987
- EPRI NP-5173, April 1987
- EPRI NP-5246, June 1987 l
- EPRI NP-5329, July 1987 l.
F. Ammirato, EPRI NDE Center, presented a status report on inspection of cast stainless steel. He stated that 75 specimens in 9 configurations were available for the program. He also stated tha' field application activities were performed on Braidwood (October 26-30,19878), Trojan l
! (April 2-12, 1987), Arkansas (November 3-5,1986) and Vogtle (June 17-18,1985). The preliminary conclusions of the program so far are as r follows:
l l
o No single, general NDE technique has been identified for inspection of cast stainless steel, although effective NDE techniques are available for a few specific conditions.

o Signal processing can improve results and that field trials are valuable learning experiences.
o Detection Statistics (preliminary):

- One-sidedaccess(in-progress)
J. Adamonis/R. Richel, Westinghouse, discussed the status of demon-stration and flaw detection and characterization capabilities for ultrasonic inspection of PWR main coolant loop welds. The manual inspection program is now complete. All 75 cracked samples have been examined manually and a final report describing the results will be completed by the end of March 1988. It was stated that results of the manual inspection program could lead to future improvement of inspection results, if the following items are given proper attention:
o Knowledge of the fabrication materials, o Knowledge of the nature of defects, o Improved understanding of the sound team propagation mechanism, i
