Item 1 Eetermine if your facility contains the flued head design for penetration connections, or other designs with containment boundary butt veld (s) between the penetration sleeve and process piping as illustrated in Figure NE 1120-1, Winter 1975 Addenda to the 197h and later editions of the ASME 3&PV Cede.
Restonse to Item 1 The Big Rock Point Plant contains the folicving types of mechanical penetrations as described above:
A) Total Penetrations:
11h
- 3) Flued Head Design Penetrations:
O C) Butt Welded (piping):
35 D) Electriesl Penetrations:
L8 E) Socket Welds:
19 8
F) Miscellanecus:
12 ID 8007140WY
2 Item 2 If an affirmative ansver-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 veld 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 including extent of repairs and description.of defects encountered during repair, if known.
Response to Item 2 A) The containment structure at the Big Reck Point Plant was designed in accordance with the requirements of the ASME Code,Section VIII,1959 Edition, per the Big Rock Point FHSR, Section 3.2.3.
Reg. Guide 1.19 was not in effect during the design and construction of the Big Rock Point Plant and does not impact the design / inspection of the penetrations.
B) No NDT required during construction.
C) See Attachment 1 D) There are no records of repairs made to these velds.
Item 3 For.those facilities committed during construction to perform volumetric examination of such penetrations through SAR co=mitments waich have not performed radiography, justify not performing radiography or submit plans and schedules for performing radiographic exa=inations.
Response to Item 3 The Big Rock Point Plant had no committment to perform radiographic exsmina-
