'UBCOMMITTEE REVIEW FOR FULL-TEPJ! OPERATING LICENSE llembers of the t!onticello ACRS Subcommittee, H. Etherington and H. S. Isbin, met in Washington D. C. , on September 11, 1972, with Nortnern States Power Company (NSP) and AEC Directorate of Regulation (DR) representatives to review the NSP application for a full-term operating license (FIDL) dated June 15, 1972, and the AEC Directorate of Licensing (DL) Saf ety Evaluation dated August 25, 1972. DL was questioned about General Electric report NEDO 10299 (January 1971),
Flow Distribution Measurements in Monticello Core, specifically whether or not we had considered this report in the Monticello Safety Evaluation for a FTOL. We responded that the repor t had nut been evaluated as part of the DL Safety Evaluation.
Mr. E. C. (A1) Ward was the spokesman for the NSP representatives when they joined the meeting and began their formal presentation. -An agenda for the meeting and a list of NSP attendees was distributed while Mr. Etaerington, Chairman of the Subcommittee, made his opening remarks which included plans f or a second Subcoamittce meeting prior to the full ACRS meeting which, at the conclusion of the meeting, was tentatively scheduled for October 5 or 5, 1972.
NSP f ollowed the attached agenda with f requent references to their FTOL application. Dana Ditmore of General Electric (GE) presented -
the f ollowing comparative fuel information (not previously presented) as a oasis f or the conclusion that GE fuel clad creepdown is negligible and that, in accordance with GE NEDO 1050, " Fuel Irradiation Experience",
supported by extensive visual, neutronic and gacma graph examination of GE irradiated fuel, there is no evidence of fuel clad collapse and none is expected.
Clad creepdown is an important clad collapse consideration, as GE sees it, based on the limited nonproprietary information on Ginna fuel clad collapse made available to them by the AEC.

No such indications were expected or discovered. He also noted that total length of fuel columns had not changed by more than 0.5% and that this value may be lower because good preirradiation ref erence measurements were not made.
The Subcommittee requested:
- 1. NSP to furnish copies of all agreements with the State of Minnesota or other state agencies.
- 2. NSP to provide isotope release limits permitted by the State compared with proposed Appendix I to 10 CFR Part 50.
- 3. A point by point review of the P. A. Morris October 1971 letter to USP.

- 4. Reconsideration of the significance of the grinder caused ,
torus damage.

- 5. Reevalnation of the effect on fuel life of transients such as pribary u stem / blawdowns. [CE had indicated that fuel rous with hydride blisters could pop earlier but that net (end of core life) fuci rod douage would not be increased by such blowdown incidents.)
- 6. A reanalysis by General-Electric of the consequences of '
I uccond, or the f astest possible, isolation valve closure instead of the minimum c) sure time of 3 seconds as currently required by the Technical Specifications.
- 7. An evaluation by DR of comparative isolation valve closure and Icak rateo for operating BWRs.
- 8. An evaluation by DR of of f-gas release experience as f uel depletes at other BWRs, and modifications that have been made at other operating LWRs.
- 9. An analysis of the effects of transient iodine releases during power level changes or blowdowns.
At the conclusion of the meeting, the Chairman- confirmed the necessity ,
for another Subcommittee meeting prior to the full ACRS meeting early in October to review in detail (2-3 hours) with the DL staf f the DL Safety Evaluation for Monticello', to consider NSp evaluation of a number of significant abnormalities such as those revealed by NSP in Attachment 7, and other generic items to be identified by Dr.1sbin and made available to NSP through the DL staff. Dr. Isbin was to 4
consult with tne full ACRS committee with regard to desirability for the -
DL staf f or the ACRS to meet with state officials to review arrange-ments aud agreements between NSP and State of Minnesota agencies as related to accidents at Monticello that could affect the health and -
safety of the public, and advise us of the outcome.
