Follow Up Questions To UCSB Licensee's Response to Original Question #

3 In your response to our question you state in part that "... the carbon steel outer shield tank is not appreciably activated", and you imply that this tank will be disposed of as nonradioactive material. The .

regulations do not identify levels of licensed material that are below regulatory cnneern. All licensed material must be disposed in accordance with the regulations in 10 CFR 20. In your response indicate your commitment to dispose of any radioactive licensed material by means provided in 10 CFR 20, 9 In your response to this question it is implied that you may have to store licensed material, intended for disposal, after you have requested that your license be terminated. The regulations do not permit the possession of licensable material without j a license, even if packaged for disposal and only stored prior to being shipped for disposal.

Describe your provisicns for disposition of all licensed material prior to requesting license termination. You will not be permitted to store radioactive reactor components under the General License for UCSB from the State of California.

10 Your response to this question does not include locations for the surveys on the walls, ceiling, drains, trenches or other locations. Describe more fully the locations of your sampling survey.

12 and Region V #5 As part of your final report to the NRC you will

- be required to certify that the release criteria of 5 microrem per hour above background at one l meter from any surface has been met. The indicated Micro-R-Meter is not a true dose equivalent ratemeter and does not provide a dir.:ct measurement. Describe the means (e.g.

calculations, etc.) that will be used to conclude that the above criterion has been met.

Region V #1 Describe your method for analyzing the shielding water in more detail. Your response does not sufficiently describe your analytical procedure to determine its acceptability.

Region V #3 It is not clear from your response that: UCSB management has reviewed and identified the applicable portions of the Rocketdyne radiation protection program to assure that the Rocketdyne program complies with the conditions and commit-ments of the UCSB license. Please clarify your response.
