June 11, 1982 Mr. Matthew C. Jay 8411 Neva Avenue IN RESPONSE REFER San Diego, CA 92123 TO F0IA-82-241
Dear Mr. Jay:
This is in response to your recent undated letter in which you requested, pursuant to the Freedom of Information Act (F0IA), four categories of records pertaining to the " safe end" technique for joining or repairing piping in boiling water reactors. This confirms the information relayed during the telephone conversation between you and Linda Robinson on June 9, 1982.
Categories 1 and 2.
The NRC has no records subject to these categories of your request because the NRC neither accepts nor rejects safe end techniques for joining or repairing piping in boiling water reactors.
However, for your information and whatever assistance it may be to you, NRC staff provided the following information on this matter.
The NRC accepted the American Society of Mechanical Engineers Boiler and Pressure Vessel Code ("ASME" Code), as specified in the Code of Federal Regulations (10 CFR Part 50).
The ASME Code allows the safe end approach in fabrication.
The NRC has not approved any specific safe end technique.
The NRC only has restrictions on the materials allowed in recently 4
constructed boiling water reactor coolant pressure boundary piping, as specified in report No. NUREG-0313, Revision 1, which you mention in your request.
(The NRC staff further noted that the use of cast safe ends or weld overlaid austenitic stainless steel allowed in NUREG-0313, paragraph I.2, dated July 1977, predates your patent, and that the technical basis for allowing cast stainless for safe ends to prevent intergranular stress corrosion cracking was well known by industry prior to publication of NUREG-0313.)
Category 3.
Inasmuch as voluminous requested records exist, and in light of comments noted above, you and Ms. Robinson agreed that we would provide to you a representative listing of requested records (see enclosure, found in NUREG-75/067) and should you decide you are interested in such records you will submit a separate F0IA request to this office.

.o g,
Mr. Matthew C. Jay Additional listings of requested records are found as references in various reports.
Although references in these reports may not include all requested records, the following reports present the information upon which the NRC made its decisions in this area.
1.
NUREG-75/067, " Investigation and Evaluation of Cracking in Austenitic Stainless Steel Piping of Boiling Water Reactor Plants".
2.
NUREG-0531, " Investigation and Evalution of Stress-Corrosion Cracking in Piping of Light Water Reactor Plants".
3.
NUREG-0679, " Pipe Cracking Experience in Light Water Reac tors".
4.
GE Topical Report No. NED0-21000-1, " Investigation of Cause of Cracking in Austenitic Steel Piping".
Should you decide you would like a copy of any of these reports, you may obtain a copy by calling (202-634-3273) or writing directly to the NRC Public Document Room (PDR),1717 H Street, N.W., Washington, DC 20555.
Upon your agreement to pay the copying charges, the PDR will arrange for the records to be copied by a private contractor servicing the PDR.
You will be billed by the private contractor for the copying charges, plus tax and postage.
Category 4.
With regard to this category of your request, NRC staff g
members informed this office that all domestic nuclear power plants use safe ends. Thus, all utilities owning nuclear power plants, nuclear steam supply system manufactures, nuclear power plant architect / engineering firms and constructors of nuclear power plants use safe ends.
A listing of such organizations appears in the February 1982 issue of the magazine, Nuclear _ News, available from public sources such as your local public l ibrary.
This completes NRC's action on your request.
If you have any questions about our response to your request, please call Ms. Robinson at (301) 492-8133.
