Inspection 70-938/79-01
Dear Mr. Smith:
Massachusetts Institute of Technology submits the following information in response to your letter of April 20, 1979 (received April 25, 1979) stating that certain of our activities were apparently not conducted in full compliance with NRC requirements.
A.
Failure to post a high radiation area with the required caution sign.
The area in question should not have exhibited radiation levels in excess of 100 mr/hr.
A worker had placed radioactive material in a shielded storage cave within the waste storage area.
Upon completion of the task, he did not replace the lead shield cover over the normally shielded cave.
The i==ediate corrective action was to replace the shielding, thereby reducing radiation levels to less than 100 nr/hr at the surface of the shielding and elsewhere outside it.
In order avoid recurrences, the individual worker involved has been informed of the importance of =aking radiation ceasurements and securing the area upon ccepletion of any work involving radioactive materials. As an additional precaution, the Reactor Radiation Protection Office has instituted a daily (working day) radiation survey of the area to assure that radiation levels are as 1cw as reasonably achievable and that the area is properly posted.
This type of survey was started on March 24, 1979, so that we are now in full compliance in this regard.
B.
Failure to use a written procedure for loading and closing a package containing licensed special nuclear material.
D.
Failure to maintain a record of shipment cf fissile caterial showing the results of the determinations required by 10 CFR 71.54 for a shipment cade on August 23, 1977.
Corrective action for both of the above items of non-compliance (B & D) has consisted of drafting the required written procedure.
Included in the procedure are the routine determinations required by Theprocedurewillbereviewedandapprovedforusgjjg 10 CFR 71.54.
q90 7 p,3 0(e7
Attn:
Mr. George H. Smith hay 15, 1979 page 2 no later than May 31, 1979 unless another shipment of fissile material is made before that date, in which case the procedure will be implemented prior to the shipment.
C.
Failure to adopt appropriate procedures pursuant to 10 CFR Part 21, except for Reactor License No. R-37.
Corrective action has consisted of drafting a revised written procedure, which is to be reviewed and approved for use no later than May 31, 1979.
Please contact ce if you should have any questions regarding the above =atters.
Sincerely, wn n b
Lincoln Clark, Jr.
