1 June 10, 1988 Docket No. 50-128 Mr. Donald E. Feltz, Director Nuclear Science Center Texas A & M University College Station, Texas 77843-3575

SUBJECT:

CLARIFICATION OF MEANING OF EXPLOSIVE MATERIALS In regard to your request of May 26, 1988 for clarification of the term explosive materials, we consider the term explosive materials, as used in your Technical Specifications (TS), Section 3.6.2(a), to toean Class A explosives as defined by the U.S. Department of Transportation (49 CFR Chapter I). That is, explosive material as used in your TS means explosives which possess, detonate, or otherwise contain maximum hazard; such as dynamite, nitroglycerine, picric acid, lead azide, fuliminate of mercury, black powder, blasting caps and detonating primers.

As required by your TS in Section 4.6, however, experiments must be reviewed to assure that material being placed in the reactor and its experimental facilities does not cause damage or causes to be released excessive amounts of radioactive materials as a result of failure. Therefore, material not identified as Class A explosives, which could explode or ignite under certain conditions, must be reviewed in accordance with this section when being plac.ed in the reactor and its experimental facilities.

Sincerely, original signed by Theodore S. Michaels, Project Manager Standardization and Non-Power Reactor Project Directorate Division of Reactor Projects III, IV, Y and Special Projects Office of Nuclear Reactor Regulation ec: See next page Distribution:
