C \\ / Y ) RfAss in E TsnGAT W The investigation was conducted as a result of a written report by the subject licensee to the Director, Division of co=pitance, dated August 15. 1967; subjec.t: " Report of Inhalation Exposures at Atomic International". That report indicated a number of employees had received inhalation exposures to highly enriched uranium-aluminum (UA1) dusts. SUytRY 0? TACTS The licensee began using highly enriched uranium aluminum (UA1) in powdered form about January, 1966 From that time until approximately July, 1967, thirty-one licensee employees were exposed intermittentiv to urcnium dust in conty trations in excess of 10 CFR Part 20 airborne limits for insoluble uranium-234U in restrie-ted areas. These exposuyes resulted in the deposition of between one and four eax-ieum permissible lung burdens in at least six c-'ployees. The licensee's evaluation of personnel exposures is continuing. The cause of the incident is attributed to a number of citenstances and conditions ,hich are listed below: w Effective communication in health physics matters did not exist between the a. Supervisor, Radiation Safety Unit, end his lead engineer. b. The health phystes lead engineer did not present an integrated analysis of survey data indicating trends in' airborne concentrations. The licenree erroneously assumed the UA1 product to be soluble in the hu an c. body and thereupon based his eclection of airborne concentration limit and his evaluation of bioassay results. tion in safety factor, Thet assu ption introduced a six-fold reduc-d. The licensee applied his (erroneous) airborne concentration limit for soluble uranium-234 on the basis of general room air samplies rather than breathing zone sa:-pling..The room air concentrations appear to be lower than breathing zone concentrations by at least a factor of ten. The licensee did not adequately control equipnent surface and floor contamina-e. tion levels in his UA1 powder production area although internal procedures rea quired such control. f. The containment equipment used in urenium powder handling was inadequately de-signed. The licensee has taken the following action to correct and control high uranium airborne concentrations and to minit:ize or preclude similar inciden'ts in the future. The health physics lead engineer has been replaced by a professional health physicist assigned to the pwder. production area of the licensee. improvement in the containment design cnd ventilation of processing equip-Interin cent along with a strong surface contamination control effort hes resulted in average uranium airborne concentration of approximately 5 x 10-11-c/cc at operator breathing zones. The maxi z:m permissible air concentratien for insoluble uranium <234 (10 CTR 20) is 1 x 10-10,efee, The licensee has instituted a conthly radiation safety report to be executed by health physics technicians and distributed to health physics supervision. The report is designed to indicate trends in health physics survey results. The licensee is continuing to evaluate personnel exposures using excretion data as well as whole body counts. Overexposed personnel have been re=oved from work with reficactive meterials. The licensee has completely redesigned his uranium powder production line, providing eiere operating room, better ventilation, and glove box containment of most operations. Page f _ of.2.

When asked if a review of the radiolo;ical hazards associated with this production had beca cade, they replied that such a review had been'cade but that this recent experience showed that review was inadequate. A review of the nuclear safety and production operating proccdures for the Advanced Test Reactor and hperiment:1 Test Reactor fuel production indi-cated that 3:r. K. L. !!attern, Chairn n, Fuel Co:::nittee, had given his sig-nature approval of these procedures from the radiological safety point of view. 1:r. Alexander and the investigator noted that these procedures are addressed primarily to nuclear safety and contain little or no radiological analysis.

25. Uhen asked to produce radiatica safety procedures for operation in the pov-der production area,1:r. Alexander relarenced the license S:01-21 renewal ap-plication dated June 29, 1955

"'hzt application has, es an cmandment, a loose-leaf binder which includes in its Section III the health and safety procedures pertaining to fuel m nufacturing. Region V can find no licenso ref erence to those procedures.

12. Alo::nder also referenced the internal procedure for radiation safety. This procedure is attached to this report as

• e x E.

26. Review of Annex E reveals the follcuing:

The date of the radiation safety procedura (Annex I) is Dece ber 9,1955, a. i.e., approximately twelve canths after the beginning of fuel manufactur-ing operations in the powder area. b. Section III.A.2 of that procedura rccuires inmedicto cicaning of surface contacination above est:blished limits. The licensee's survey results (Annex C) shou that contenination levels chove the licensee's limit rou-tinely existed in the powder area prior to July, 1967 c. Section II.C.2 requires that vork secticas at which glove box cnd hocd air flow rates fall below 100 lineer fact per minute shall be closed until tho situatica is corrected. '2. Alexander stated that the Radiation Safety Unit had not monitored the linas; air flow rate at those operations be-ccuse it was the responsibility of tha Industrial Safety Depart =en:;. Alexander indicated that flow rates at hoods and at the door to the ccc-pact press enclosure had fa'.len below 103 linear feet per minute without his knowledge. }Ie further indicceed that the licensee's investig:tien of this incident disclosed that a linear velocity near 300 feet per t:inute was required to control airborna contc=instion, d. Section V.B requires that all ::diolo;ical deficiencies in operations be reportcd to supervision. Alcxandar stocad that he had conferred alt:ost daily with 1:. Johnson and had been assured thct operations in the potzder production area vcre satisfsetcry from the radiological safety stcndpoint. A review of survey records indicated th:t airborne end surfcce contamina-tion data for the powier predaction crea had been compiled on a quarterly basis and presented to ;t. Alexander Ly :2. Johnson. Carrective ' ctions listed in paragraph 19 of this report were taken by the li-27 a censco to bring an immediate airborno contcmination proL1cm under control. Tha licensee has notified the thirty-ono cmployces of their potential overen-posures as required by 10 CT2 20.?O5G). In cddition to those actions already taken, the licensee has the following plc for pern:ncat correction: According to Alexander, tha iml% cirborre limit of 10 Cpa 20 is being a. and vill be used in connectica with che production of UA1 powders.

Uilliam Lillingham vill continua es full-:ica supervisor in the powder pro-due: ion arca. Licenses representztives assured the investigator that ;2. Willica Eeine (present health physics powder arca supervisor) was eninently = ore qualified than his predecessor, 12. Johnsoa. s

31. Alexander gave his assurance that the present de;ree of control over the cir-borne ccatarination probica would con:inua throu;h the instc11ation of the n:V pcuder production line. Ee added th:: breathin; zone air sa. plea sould be continued after the new line ves pisecd in usa.

32 The investigator stated that although no specific references appeared in 11-cesse SNM-21, the licensee failed to follou internal procedures for monitoring powder production ar'ea ventilction cnd decon:::iaation of surfaces. Further-core, he stated that tha Eccith cad Safe;y, Scction III of the licensec's application for reneual and c=entment of S;n-21 dated June 29, 1955 contcined conditions which were not followed in tha pctdcr production area. Specifi-cally, that section states in parc;reph 9, pace III-6 that " Dry machining of erriched uranium is carried out in the glove boxes". The investigator indi-cared that the licensee was in cppcrent nonce pliance with that condition in that glove box containment was not provided for a ne:ber of operations in the powder production area and stated : hat the violation was contributory to tha incident. (Upon subsequent review of licensa 323-21 b; 2a; ion V, it vcs discovared that the procedures attached to the cpplicction d::aa Juna 29, 1965 were n4ver in-corpora:.d in that license.

12..;12x:nder was so informed by a talcphone ec11 on October 19, 1967, at shich tira :he ci:: tion va retrac:cd on that tech:1-cc1 ground.)

In reply, l1. Alencnder it.dic:ted the: tha incent of p:::;reph 9, p ;e I;!-5 of the reneual :pplication uss not to rascric: all operations to glove bon con-tiincent. In the ensuin; discuasics, it uns noted ths giova box contcin= cat ves acadad and would be used in :ha neuly-desig cd production line for cil pov-dar operztions.
