Reference:

Letter from F. R. Standerfer, 4410-85-L-0110, to B. J. Snyder, dated June 18, 1985 In order to complete our review and evaluation we will require additional information. Picase respond to the following items so that we may respond to your request.

1.

Describe your program for controlling the use of respirators and minimizing their impact on comunications. Your discussion should include equipment, training, and results achieved.

2.

It is not clear from your submittal what fraction of the iodine you are assuming in your accident scenario is in particulate, organic, elemental, etc. form; please clarify your source term assumptions. What are your plans for the use of adsorbents to protect against iodine? Do you intend to apply for such an exemption; if so when? The information provided by your staff, to date, indicates that an exemption to 10 CFR 20.103 for

'odine protections would be required.

3.

Describe your plans for assuring that personnel accessing the control room during an emergency have respirator qualification, fit proper respirator type in stock, eyeglass inserts, etc.

4.

Describe your provisions for physiological stress associated with long tenn (greater than two hours) use of respirators, especially assuming the control room chillers are inoperable. This should include a description of available relief crews and your experie1ce with use of respirators in adverse conditions such as those that might occur with chillers inoperable.

!!r. F. R. Standerfer October 2, 1985 l-i S.

Since the safety evaluation assumes an infiltration of 1350 cfm you should either retain your current method of verifying the control room i

envelope is intact or a new surveillance should be developed for this i

purpose. Which strategy will be employed?

j 6.-

If there is a problem with the ventilation system which brings its i

operability into question will you have a method of checking it quickly?

i (Currently flow can be ascertained via control room readout. Uill there i

be a method to determine if you're meeting the a pressure requireatent?)
