110NTICELLO HUCLEAR GENERATING PIANT l DOCKET No. 50-263 LICENSE NO. DPR-22 LICENSE AMENDMENT REQUEST DATED JANUARY 18, 1978 PROPOSED CHANGES TO TECHNICAL SPECITICATIONS Pursuant to 10CFR50.59, the holders of Provisional Operating License DPR-22 hereby propose the following changes to the Appendix A Technical Specifications:
PROPOSED CilANCES A. Section 1. Definitions Add the following new definitions to Section It AB. Pressure Boundary Leakage - Pressure boundary leakage shall be leakage through a non-isolable fault in the reactor coolant system pressure boundary.
AC. Identified Leakage - Identified leakage shall be:
- 1) Reactor coolant leakage into drywell collection systems, such as pump seal or valve packing leaks, that is captured and conducted to a sump or collecting tank, or
- 2) Reactor coolant leakage into the drywell atmo-sphere from sources which are specifically located and known not to be Pressure Boundary Leakage and Which do not significantly impair the methods used to detect reactor coolant Icakage.
AD. Unidentified Leakage - Unidentified Icakage shall be all reactor coolant leakage which is not Identified Leakage.
AE. Non-Conforming Linen - Pipe and fitting material, including veld metal, which has not been shown to be highly resistant to oxygen-assisted stress corrosion in the as-installed con-dition. Type 304 stainless steel is non-conforming unless:
- 1) All piping and welds aFi~in the solution annealed condition, or
- 2) The component is protected from exposure to reactor coolant by cast or veld overlay austenitic stain-less steel with 5% minimum ferrite or other materials having high resistance to oxygen-assisted stress corrosion.
AF. Service Sensitive Lines - defined as those that have ex-perienced stress corrosion cracking in boiling water reactor service or are particularly susceptible to such cracking because of high stress or because they contain relatively stagnant, intermittent, or low flow coolant.

- 2. Add new pages 189U and 189V to Exhibit B of Monticello License Amendment Request dated August 30, 1977 to revise the Bases
. to include the above changes. Refer to pages 1890 and 189V in l Exhibit B, attached.
! REASON FOR CHANCES These changes are being proposed at the request of the NRC Staff. They are consistent with the recommendations contained in NUREG-0313, July,1977,
" Technical Report on the Material Selection and Processing Guidelines for BWR Coolant Pressure Boundary Piping."
) All of the reactor coolant system pressure boundary piping and fitting material, including weld material, has been reviewed and compared to the material' selection and processing guidelines contained in NUREG-0313.
Materials that do not meet these guidelines are identified in Table 1 (Non-Confoming Lines which are not Service Sensitive) and Tabic 2 (Non-Confom-ing Lines which are Service Sensitive). Tables 1 and 2 contain the following
, infoma tion:
t
- a. System identification
] b. Weld identification i c. History of completed examinations l d. Examination sucnary and future examination schedule All Non-Confoming Lines at Monticello consist of pip;ng constructed of
- - Type 304 stainless steel. Field welds in these lines were not solution annealed. Service Sensitive Lines at Monticello consist of
- a. Core spray lines
- b. Recirculation bypass lines-(welds between 304 and 304L stainless steel) l To date, no other lines can be statistically demonstrated to be l Service Sensitive.

- l l The proposed changes conform to the requirements of NUREG-0313 with j one exception. Type 316 stainless steel is not considered to be ,
1 Non-Conforming in the mill annealed plus field welded condition.
] General Electric Company records show that no incidents of stress corrosion cracking have occurred in any Type 316 stainless etce.
1 pressure boundary line in which the piping system is in the i metallurgical condition of ' bill anneated + welded." 1145 veld J joints of Type 316 stainless steel have performed satisfactorily in 1 BWR service with no cracking incidents. 305 of these Type 316
, stainless steel veld joints have seen duty in Service Sensitive '
Lines. Laboratory tests by General Electric have confirmed these i obse rva tions .
l Type 316 stainless steel is used at Monticello in the Residual IIcat
, Removal System piping. These lines are listed in Table 3 which
- also contains a sunmary of examinations performed on them. No 4 augmented inspection of these lines is planned.
SAFETY EVALUATION a
j '
1 The proposed changes to the technical specifications consist entirely of additions to the limiting conditions for operation and surveillance require- ,
i ments now in effect. The proposed measures to detect the occurrence of
! stress corrosion cracking are positive actions consistent with existing
) technology.
j 1mplementation of these proposed changes will significantly reduce the possibility that stress corrosion cracking will go undetected.
