SUBJECT:
SID9tARY OF JANUARY 8,1981 MEETING WITH PtBLIC SERVICE COMPANY OF INDIANA. INC.
A meeting was held on January 8,1981 in Bethesda, Maryland with Public Service of Indiana, Inc. (PSI) to discuss the results of inspections and additional testing performed by PSI relating to cadweld splices at Marble Hill Units 1 and 2. The meeting agenda, a list of th9 attendees, and handouts provided during the meeting are enclosed (Enclosures 1, 2, and 3).
PSI's inspection of accessible cadwelds, as par *, of the " Construction Verifi-cation" program at Marble Hill Units 1 and 25 revealed neberous visual deficiencies which exceeded tne acceptance criteria,both the Marble Hill project and manufacturer's specifications. Of the 2431 accessible cadwalds inspected, 504 cadweld's (20%) were identified to have deficiencies which would cause rejection of the cadwelds under the original project specifications. Approximately 50% of the deficient cadweids }
had gage mark indication problems although there is not a requirement for permanent 'l markings. Approximately 7500 cadwelds are buried in concrete and therefbre not accessible for inspection.
l Tests on accessible cadwalds were performed to evaluate the types of deficiencies in the accessible population to draw conclusions on the acceptability of the buried cadwelds. A random sample of 59 cadwelds were selected and reinspected.
For cadwelds which failed the visual inspection or radiography criteria, tensile ;
tests were performed. All 59 cadwelds met the visual inspection criteria or l had acceptable tensile test results. An additional sample of 58 cadwelds with gage mark deficiencies, biased by selecting the worst cases, were radio-ggepted. Three cadwelds were additionally identified to exceed gage mark tolerances. These were tens 11ed tested and had acceptable results. Also, 21 cadwelds with the worst case physical deficiencies were removed and tensile l tested. These 21 also set the tensile test requirements. Based on the acceptable results from the additional tests and inspections performed and ,

- The cadweld deficiencies at Marble Hill were clearly beyond those covered by NRC Regulatory Guide 1.10 and normal industry practica. The NRC staff had previously expressed that in addition to reviewing the strength charac-teristics of the defective cadwelds, PSI should evaluate the affects of l
' strain (softening) on the behavior of the structures. To address this issue l PSI evaluated the past and current code requirements for cadweld splices, )
compared testa performed for the cadweld manufacturer (Erico) and the situation edfMarble Hill, and performed stress analysis of structures assuming no load carrying capability for physically defective cadwelds. In sinumary, PSI concluded that (1) strength ndrstrain is the primary criterion of concern; (2) the Erico tests, although more severe than the situation at Marble Hill, showed acceptable results; and (3) the ACI code allowable stress-fbr reinforcing bar was met for the worst case (crecking is not significant). R In conclusion, the NRC staff provided the following cannents:
1.
PSI should submit a written report describing with sufficient detail the discussions presented during this meeting. It was agreed that the report would be previded by January 23. 1981.
2.
As an itan for inferimetion, the Region III Office would review the results of the radiography test program.
3.
PSI should rejectable cadwelds. address the corrective actions, if any, planned for the visually The NRC would review those specific cases in which removal and replacement of cadwelds would be impractical (such as "B" type splices attached to the contaissent liner).
4.
PSI should indicate in the written report the acceptance criteria that would be used for the future production of cadwelds. PSI indicated that thesubsequent for original Marble work. Hill project acceptance criteria would be applied l S.
l PSI sho41d provide in the written report a. discussion of the effects of
! deformation (deflection) on the structurns related to the analysis assaing i
no load carrying capability for the physically defective cadwelds, 6.
A detailed NRC review of the written report will be necessary, but it appears based on the discussions during this meeting that additional testing will not be required. PSI would be formally notified if additional actions are required.
The written report has been submitted to the NRC and is being initially reviewed in this office. It is anticipated that the review of this issue will be formally transferred to MRR. The Structural Engineering Branch, NRR has been kept informed of this issue at Marble Hill and has been involved in discussions with the IE staff.
