REQUEST FOR ADDITIONAL INFORMATION REGARDING l -

RADIOLOGICAL ASPECTS OF RTD BYPASS MANIFOLD SYSTEM REMOVAL

1. Describe the actual hardware changes and activities that will be made to j accomplish RTD Bypass Manifold System removal. Include those construction

steps which result in occupational exposure to personnel or generate radioactive waste. Identify differences, if any, in these changes and activities for the two McGuire units.

2. Provide an estimate of the occupational radiation dose detennined for the overall RTD Bypass Manifold System removal project at McGuire 1 & 2. This should include the following:

a) doses and manpower for major subtasks b) typical dose rates expected c) maximum dose rates expected, and locations.

i 3. Provide a comparison of occupational dose estimated for task perfonnance i and dose to be avoided (e.g., reduced leakage and maintenance, ISI require-

ments reduced, reduced numbers of shutdowns, reduced general area dose rates, fewer " hot spots" and crud traps) over plant life by removal of the RTD Bypass Manifold System.

4. Identify measures to be taken to assure that doses to workers during task perfonnance will be ALARA. This should cover, for example, task planning, special training, use of mockups, area and system decontamination and airborne radioactivity, efforts to minimize number of workers, and applica-tion of experience from similar efforts in the industry.

5. Identify the types and volumes of radioactive waste which are expected to be generated (e.g., piping, components, insulation), and discuss disposal

, plans for these wastes. '

l 6. Identify and briefly discuss any associated with this task (e.g., very special highradiological problems dose rates, very high contamina- which may be tion levels, high radioiodine levels, need for multiple dosimetry, brief stay times).
