Tuesday, July 5, 1994 10:14 am Subjects NC TECHNICAL ASSISTANCE REQtTST Attached is our response to NC's TAR.
There was not enough information for us to specifically answer Ms. Haden's request. The attachment references information that is required to perform the review and which upon review would address Ms. Haden's request (bullets 2,3, and 4 of Richard Woodruth's letter)
Bullet 1.of Dick's letter is unclear.
If they mean what training does RTI have to have in_the way of engineering design, the answer is - no specific training is required.
If you have any questions about this response please feel free to contact me.

Q RESPONSE TO NORTH CAROLINA'S-TECHNICAL ASSISTANCE REQUEST We have reviewed the package provided to Ms. Haden.
In order to
-review the new source rack design and its' acceptability for licensing, at a minimum, the design specifications of the current system are required.
These. specifications are required in order to answer the following questions.
- 1) What are the dimensions (including tolerances) of the current rack system (i.e., modules, sources, rack, etc.)
- 2) How is the current rack system moved from the shielded to the exposed position?
What are the specifications (i.e.,
-rated-loads, torque, speed, etc.) for the pneumatic cylinders, motors or other components that are used to move the source rack?
- 3) What is-the maximum weight of the current rack system?
- 4) What are the materials of. construction of the current rack system and why were these materials chosen?
In addition, RTI needs to' submit information regarding the following:
'1) The new rack design may affect how the irradiator is licensed-(i.e.,-' source loading / unloading, maintenance and emergency procedures, increased radiation levels, etc.).
The applicant should submit any necessary information that t
may affect the current license.
- 2) Weight of the new rack design when fully loaded in the exposed position and shielded position.
For the exposed position, the weight should include the weight of'any water that may be trapped (no drainage holes shown on rack).
- 3) How is the eye bolt attached?
Is the eye bolt welded to the rack?
j
- 4) Diameter of the source rack guide tubes.
- 5) Any prototype testing performed on the rack (i.e., drop l
test, temperature test-(warpage), etc.).
