United States Nuclear Regulatory Commission Attachment II to Serial: RNP-RA/04-0097 Page 1 of 2 H. B. ROBINSON STEAM ELECTRIC PLANT, UNIT NO. 2 60-DAY RESPONSE TO NRC BULLETIN 2004-01, "INSPECTION OF ALLOY 82/182/600 MATERIALS USED IN THE FABRICATION OF PRESSURIZER PENETRATIONS AND STEAM SPACE PIPING CONNECTIONS AT PRESSURIZED-WATER REACTORS" NRC Bulletin 2004-01, "Inspection of Alloy 82/182/600 Materials Used in the Fabrication of Pressurizer Penetrations and Steam Space Piping Connections at Pressurized-Water Reactors," in Section (1) of the Requested Information, requires that within 60 days of the issuance of the bulletin all pressurized-water reactor (PWR) licensees provide to the NRC the requested information.

NRC Request (a) A description of the pressurizer penetrations and steam space piping connections at your plant. At a minimum, this description should include materials of construction (e.g., stainless steel piping and/or weld metal, Alloy 600 piping/sleeves, Alloy 82/182 weld metal or buttering, etc.), joint design (e.g., partial penetration welds, full penetration welds, bolted connections, etc.), and, in the case of welded joints, whether or not the weld was stress-relieved prior to being put into service. Additional information relevant with respect to determining the susceptibility of your plant's pressurizer penetrations and steam space piping connections to [primary water stress corrosion cracking] PWSCC should also be included.

Response

Based on a review of technical information and specifications it has been determined that there are no Alloy 82/182/600 materials used in the fabrication of any of the pressurizer penetrations or steam space piping connections for the H. B. Robinson Steam Electric Plant (HBRSEP),

Unit No. 2, pressurizer. No additional information has been determined to be relevant with respect to determining the susceptibility of the HBRSEP, Unit No. 2, pressurizer penetrations and steam space piping connections to PWSCC.

NRC Request (b) A description of the inspection program for Alloy 82/182/600 pressurizer penetrations and steam space piping connections that has been implemented at your plant. The description should include when the inspections were performed; the areas, penetrations and steam space piping connections inspected; the extent (percentage) of coverage achieved for each location which was inspected; the inspection methods used; the process used to resolve any inspection findings; the quality of the documentation of the inspections (e.g., written report, video record, photographs); and, the basis for concluding that your plant satisfies applicable

United States Nuclear Regulatory Commission Attachment II to Serial: RNP-RA/04-0097 Page 2 of 2 regulatory requirements related to the integrity of pressurizer penetrations and steam space piping connections. If leaking pressurizer penetrations or steam space piping connections were found, indicate what followup NDE was performed to characterize flaws in the leaking penetrations.

Response

Based on the response to Item (a) above, i.e., there are no Alloy 82/182/600 penetrations or steam space piping connections in the HBRSEP, Unit No. 2, pressurizer, this requested information is not applicable.

NRC Request (c) A description of the Alloy 82/182/600 pressurizer penetration and steam space piping connection inspection program that will be implemented at your plant during the next and subsequent refueling outages. The description should include the areas, penetrations and steam space piping connections to be inspected; the extent (percentage) of coverage to be achieved for each location; inspection methods to be used; qualification standards for the inspection methods and personnel; the process used to resolve any inspection indications; the inspection documentation to be generated; and the basis for concluding that your plant will satisfy applicable regulatory requirements related to the structural and leakage integrity of pressurizer penetrations and steam space piping connections. If leaking pressurizer penetrations or steam space piping connections are found, indicate what followup NDE will be performed to characterizeflaws in the leaking penetrations. Provide your plans for expansion of the scope of NDE to be performed if circumferential flaws are found in any portion of the leaking pressurizer penetrations or steam space piping connections.

Response

Based on the response to Item (a) above, i.e., there are no Alloy 82/182/600 penetrations or steam space piping connections in the HBRSEP, Unit No. 2, pressurizer, this requested information is not applicable.
