~~ REQUEST FOR ADDITIONAL INFORMATION INSERVICE INSPECTION PROGRAM Arkansas 1 4 1. General Under the change in regulation,10 CFR 50.55a effective November 1, 1979, your ISI program, when finally approved, will cover the last 80 months of your current 10-year inspection interval, i.e., 'fron April 19, 1978 to December 19, 1984. Does this result in any changes you wish to make in your relief requests? Do you require other ISI relief? 2. Extant of Volumetric Examinations (Question 1, Ref. 2)- In this question you were asked whether full volumetric examinations can a be performed in accordance with code requirements for all Class 1 and 2 systems. Your response suggested that the plant has some partially inaccessible welds for which relief requests have not been prepared. For example, the use of Article I-5121 to record limited examination is discussed and the suggestion is made that "a supplemental... surface examination could be performed". Formal relief requests should be submitted on welds for which complete compli-ance with code requirements is not possible. The fraction of the weld which is inaccessible should be estimated as well as the total fraction of inaccessible welds or weld length in a given ' code item. As appropriate, a definite commit-ment should be made to perform any supplemental, alternative examinations. 3. Exemption due to Paragraph IWC-1220 of Section XI (Question 6, Ref. 2) In your response you identified Class 2E systems on your P&lD's as being ~ exempted from examination because of paragraph IWC-1220. The NRC does not accept the " chemistry control" provision of the S-75 addenda as a basis for exempting systems for inspection. You should develop an ISI program for the ECC, RHR, and CHR (containment heat removal) systems that complies with the intent of the.S addenda, in which the " chemistry control" provision has been deleted. A commit- ~ ment to such a program,with any necessary relief requests for reasons other than chemistry control, should be provided in response to this inquiry. 1 .-o, .m m
4 -~. o 4. Item B5.6, Volumetric Examination of Pump Casing Wel_ds, and Others (Ref. 2) Your response to Question 2 indicates "that relief request on this item is to follow at a later date". Possible relief requests are also pending on: (a) Question 6 - pressure testing of Class 2E systems, (b) Question 7 - pressure testing of service water system, and (c) Question 9 - supplementary information (resulting from !4 arch 1,1979 outage) re. HPI and core flood l'ine welds. P. lease provide as much of the missing information as possible. REFEREf1CESi 1. Cavanaugh, APL to Davis, 11RC, #1-107-7, October 19, 1977. ' 2.
