TEST CONDITIONS Challenge Conc.:. 5 - 10 ppm'CH I Humidity: 60 + 3% and 90 + 3% 3(minimum of six cans at-eacii humidity) ~

' Temperature: 1100F Cyclic Flow: 192 LPM for 0.82 sec.; O LPM for 1.64 sec.,

repeating this cycle throughout the test.

This gives a minute volume of 64-L.

PROPOSED LOT ACCEPTANCE PLAN 4.1.1 MIL-STD 414, Level II, AQL 1% would be used to (1) select the proper number

- of cans to test, depending on lot size, and (2) to interpret'the results regarding ' lot acceptance or failure. ,

. 4.1.2 The cans would be tested under the conditions of section 1; however, all tests would be conducted at 90% RD. Tests-would be stopped at eight hours and the precent leakage recorded at this time. From evidence presented in the preceding

sections, results et 9pg are not significantly different from those'at 100%.

4.1.3 'The percent leakage values' would be compared to the spec. limit of 1.0%, using the single spec. limit, variabibigunknown, standard deviation method of MIL-STD 414. Acceptance .would 'tx3 based on this analysis.

..of cans to test, dependingo ' n lot size, and (2) to interpret the results regarding lot acceptance or failure.

• 4.1.2 The cans would be tested under the conditions of section 1; however, all tests would be conducted at 90% RD. Tests would be stopped at eight hours and the precent leakage recorded at this time. From evidence presented in the preceding sections, results at get are not significantly different from thoserat 100%.

4.13. The percent leakage values would be compared to the spec. limit of 1.0%, using the single spec. limit, variabibi unknown, 9 stindard deviation method of MIL-STD  :

LICENSEE: Alabama Power Company (APCo) iACILITY: Farley Units 1 and 2

SUMMARY

OF MEETING HELD ON APRIL 25, 1984, BETWEEN THE NRC STAFF AND ACP0 REPRESENTATIVES TO DISCUSS APC0'S REQUEST FOR EXEMPTION TO 10 CFR 20 TO ALLOW USE OF PROTECTIVE FACTORS FOR RADI0IDINE CANISTERS k INTRODUCTION 1

The NRC Project Manager introduced the subject of the meeting as noticed on

- April 11,1984 The NRC staff was introduced. Alabama Pcwer Company (APCo) representative, Mr. Wayne Carr, was introduced. The meeting was held in response to APCo's letter dated March 5, 1984. List of attendees is attached.

4 DISCUSSION Ey letter dated Jar.uary 13, 1984, supplemented February 13, 1984 APC0 applied to the Commission for exemption to 10 CFR 20 as it relates to 4 Appendix A protection factors. The NRC review has been suspended pending APCo's obtaining additional canister qualificacion information and responding to NRC staff cor.cerns expressed in NRC letter dated February 17, 1984. APCo's letter dated March 5,1984, advised that a final response

. would be delayed unit testing was completed. APCo desired to meat with NRC at that time.-

• APCo representative, Mr. W. Carr, introduced the canister vendor.

representative, Dr. E. McKee, of Mine Safety Appliances Company (MSA) who discussed the current qualification data for their GMR-I canisters. A vue-graph presentation included the attached material. The MSA proposed-lot acceptance plan was includeo in the discussion. Dr. McKee, MSA, stated the plan would conform to MIL-STD 414, Level II, AOL 1%.

MSA letter to APCo dated April 13, 1984 was presented for information. The F letter will be submitted by APCo to NRC in response to NRC' staff concerns expressed in NRC letter dated February'17, 1984. Other NRC concerns expressed in NRC letter dated February 17, 1984 were discussed. APCo agreed to provide a detailed response in the near future.. At that time the NRC

• staff review would continue.
