BRUNSWICK STEAM ELECTRIC PLANT UNIT NUMBEP5 1 & 2 REQUEST FOR ADDITIONAL INFORMATION Inservice Inspection Program Review Materials Engineering Branch
- 1. The Bruntwick Steam Electric Plant inservice iospection program states that two examination category B-B welds in the reactor vessel ce considered inaccessible for volumetric examination due in part to high radiation levels. Esi'aste the radiation exposure in man-rem to conduct these examinations and discuss the feasibility of increasing the extent of examination on accessible category B-B welds to compensate for the examinations which cannot be performed.
- 2. The ISI program contains a request for relief from volumetric examination of welds in several Class 1 lines based on no safety consecuences of failures within these lines. Relief can only be granted for examinations which are imoractical due to the limitations of design, geometry, or materials of construc-tion of components, as stated in 50.55a(g). Your justification does not meet these criteria and relief cannot be granted based on the information supplied.
- 3. The ISI program states thtt one weld in each Type A containment penetration is inaccessible for volumetric examination.
Indicate the type and proximity of leak detection systems to each of these penetrations. We will require augmented examination of the outer out-of-containment Class MC/ Class 1 or 2 containment pressure boundary weld using volumetrfc or surface techniques where practical.
- 4. The code recuired volumetric examination of various welds in pipe of greater than.3 inch wall thickness is neither specified in the examination tables nor covered in a relief request. Modify the tables to include volumetric exam-inations where recuired.
- 5. Describe the limitations of design or geometry which make volumetric or surface examinations of lines inside the suppression chamber impractical.
- 6. Relief was requested.from the visuel examination recuirement for the recirculation pump internals. Provide the following additional information for our review:
I
- a. the specific tasks and man-hours for dissassembly of the pump.
- b. The estimated radiation exposure in man-rem resulting from these examinations.
- c. The field experience of the casing material in this applicaticn.
In addition, submit a proposal for cotMucting thickness measurements of the casing with UT for detection of' internal degradation.
- 7. Several Class 1 welds are described as having limited accessibility for volumetric examination. For each weld, indicate the ASME Code examination category, the design or access features which prevent access, the estimated percentage of code required volume which can be examined, and any surface examinations-performed to supplement the limited. volumetric examinations.
5
' 8. The examinations scheduled for Category B-G-1 bolting in your procram are not in accordance with the code requirements. Modify the program to include the code required volumetric ard surface examinations.
