ATIPLIFENT I OYSTER CREEK NtK1 EAR GENERATING S'IATION I. E. BUILETIN 80-08 1.
Determine if your facility contains the flued head design for penetration connections, or other designs with containment boundary butt weld (s) between the penetration sleeve and process piping as illustrated in Figure NE 1120-1, Winter 1975 Addenda to the 1974 and later editions of the ASbE B&PV ODde.
Response
We have determined that 17 containment penetrations are of the type illustrated in Figure NE 1120-1, Winter 1975 Addenda of the ASbE Boiler and Pressure Vessel Code.
2.
If an affirmative answer is reached for Item 1, determine the following:
a)
Applicability of the ASME Code including year and addenda and/or Regulatory Guide 1.19, b)
Type of nondestructive examinations performed during construction, c)
Type of weld joint (including pipe material and size) and whether or not backing bars were used, d)
Results of construction nondestructive examinations, i.e.,
if repairs were required, this should be identified includ2ng extent of repairs and description of defects encountered during repair, if known.
Response
a)
All joints are full penetration butt welds in accordance with ASbE Section III, 1965 and the addenda in effect at August 1967.
b)
See Attachment II.
c)
See Attachment II.
d)
All construction nondestructive examinations wre acceptahle except for Reactor Feedwater system penetration welds F-RF-N1, F-RF-N2 and F-RF-S1 which were rejected for porosity. The e.xtent of the repairs i
is not known; however, the radiographs perforned after l
repairs were acceptable.
l Cont'd... 2
ATIAQs err I Page 2 3.
For those facilities cmmitteri during construction to perform volumetric examination of such penetrations through SAR com-mitnents which have not performed radiography, justify not performing radiography or subnit plans and schedules for parforming radiographic examinations.
Response
All of the information for the welds is not available at this time. Further efforts will be made to find the weld records for the Liquid Poison System (weld SW NP2-B) and Reactor Feedwater Systen (welds S1367 and S1364). A written response will be made within 45 days of this date containing the weld information requested or a schedule for perfornung radiographic inspection of the above welds if physically possible.
