(a),Unit 3 The extent of the examination of these systems is marked in green adjacent to the appropriate components.
Examination of Class 1 canponents and systems (and their supports) were conducted to the ASME Code Section XI (1970 Edition through the Winter 1970 Addenda) during the Fall 1974,
- 1975,
& 1976 and Winter 1977,
& 1979 refueling outages.
The examinations were performed by Westinghouse (W) in 1974 and by Southwest Research Institute (SwRI) thereafter-The nondestructive examination procedures (for Class 1 components and systems) and the results of examinations are on file at the plant site.
The procedures have been qualified by W and SwRI and contain acceptance criteria for each examination.
There were no reportable examination findings.
Unit 4 The extent of the examination of these systems is marked in green adjacent to the appropriate components.
Examination of Class 1 components and systems (and their supports) was conducted to the ASME Code Section XI (1970 Edition through the Winter 1970 Addenda) during the Spring 1975 and the Spring 1976 refueling outages.
Examination of Class 1 and Class 2 components and systems (and, their, supports) was conducted to the Technical Specifications and the:ASME Code Section XI (1974 Edition through the Summer 1975 Addenda); during the Summer 1978 and the Spring 1979 refueling outages.
