D ATTACISEhT A The reference (a) letter described how Commonwealth Edison would meet the reference (b) license condition.
For doors #377, 380, 446, 447, 452, and 453 CECO stated " Remove existing surface applied unlabeled door stops and install Pioneer Fireproof Door Company's "PIO-SEAL" door stops...
(for the aforementioned doors). UL will provide a letter stating that this construction is identical to a tested assembly." CECO considered that letters from U.L. dated April 22, 1983 and May 15, 1986 were sufficient to comply with the commitment.
A recent Region III inspection and phone coversation between NRR (9-10-86) and CBCo has determined that the two U.L. letters do not meet our commitment as stated in our 1983 letter. Accordingly CECO agreed with NRR that our previous commitments (regarding doors 377, 380, 446, 447, 452, 453) will be satisfied by completing the following:
1.
Forward to NRR the letter from Pioneer Fireproof Door Company to U.L. dated October 20, 1982 and include a letter from U.L.
confirming that if what Pioneer says is correct, the doors could qualify to be labelled (enclosed).
2.
Have U.L. physically verify the installation of Pioneer's j
"PIO-SEAL" Fire Door Seal. The schedule for this U.L. task is:
9-12-86:
U.L. at LaSalle to perform the dimensional verification of "PIO-SEAL" and obtain samples of the "PIO-SEAL" to perform chemical verification tests.
9-16-86:
U.L. will issue their report on the physical verification of the "PIO-SBAL".
l 9-24-86:
U.L. will complete the chemical verification testing of the "PIO-SEAL".
9-26-86:
U.L. will issue their report on the chemical test.
9-30-86: Ceco letter to NRR documenting closure.
I If this issue is not resolved before start-up of Unit 1 Ceco will have an hourly fire watch (both sides) on the six doors until there is resolution.

Re: La Salle Codocy Station Pioneer Job #C8300
Dear Mr. Gruszynski:
With ref erence to the letter dated 10/12/82 from Commonwealth Edison, a copy of which should be in your possession, please consider this your authoritation to rwiew Pioneer's door / frame procedures for the purpose of re-evaluating " label construction" openings. To facilitate your rwiew, the following is a brief list-ing of procedures, sections, etc. involved along with various comments relating to the Sargent & Lundy drawing #ASK92382:
A) The lef t hand column of this drawing concerns fire door frames. The 3 piece frame detailed is "as fabricated", however we cannot locata a similar detail in file R3259 or in U.L. 63.
B) Frame #296 was f abricated in accordance with R3259 'Vol.1 Sec.1 and was lab eled.
c) Frames #377-380-446-447-452-453 were fabricated similar to file R3259 Vol.1 Sec.1 Ill.13, except that in lieu of the gasket detailed, a #170 aluminum / neoprene gasket as manufactured by Zero Weatherstripping, Bronx, New York, was applied.
D) Frame #391 was fabricated as the 3 piece frame detailed except that the Zero
- 170 gasket was substitutad for the integral stop.
C.n E) Framea #149-160 are fabricated similar to R3259, Vol.1 Sec. 4 and 5 except that in lieu of glass or panel in the transom, the entire transom arca is a cased opening profile. A grille provided "by others" was installed in the transos opening.
Perhaps Commonwealth Edison can provide information on this grille.
F) The right hand column of the drawing pertains to doors, all of which are fabricatad similar to R7221 Vol. 1, Sec. 1.
In the case of doors 149-58-222-251-257-262-265-268-302 the doors were fabricated with a seamwelded edge to accomodata continued on page 2

Any dorrespondence or clarifications pertinent to Pioneer's' material should be directed to the writer's attention.
