Dear Mr. Johnson:

Be nuclear alarm system referred to in Dr. Leaders 8 letters to you dated November 28, 1958, and January 22,1959, has been inst /.dled and tested and is now in operation at the Hematite Plant. E nuclear alarm system is tested once a week by applying a radioactive schrj~e36~orie of the~ radiation detectors in the plant aisi!~~PirTo~cTic~ inspections of the c

detectors Kre Made thr66ghouilhe week to determine that they are in proper flinctioning order.

Enclosed you will find a series of instruction sheets whidi have been given to the personnel of the Hematite Plant. You will notice that the instructions have been sub-divided with one sheet of instructions detailing the emergency procedure to be followed by all personnel on the sounding of the ahrm. Detailed instructions for the Emergency Directar have not bem distributed to all personnel but have been distributed to.311 persons W1o might be called upon to perform as Emergency Director. Rese procedures are presently stored in the evacuation control center, the tiled barn, which is about 500 feet from the nearest processing area.

It is anticipated that routin_e_dd.11s will be conducted in_ the_,near future to familinize the personnel with_the pro.cedures to be followed in j

~~

the event there is i~ndclesf~lEcident.

l If yini^hhv'e'afiy~qdesiforis~concerning this alarm systen, please do not hesitate to contact us.

Gen W. Roy, Chief, Materials and Fuels Facilities Branch Division of Compliance, Headquarters MALLINCKRODT CHEMICAL WORKS, MALLINCKRODT/ NUCLEAR ST. LOUIS, MISSOURI - LICENSE NO. 24-04206 Enclosed is an inspection report, for your information, of an announced inspection of the subject byproduct material program conducted on December 6 - 9, 1971.

j A total of five items of noncompliance were noted. Three of these items related to the exposure of one individual to en excessive concentration of iodine 131 as evidenced by thyroid glar.d ceunting and the failure of 1

the licensee to report this exposure to the Coumission and to the 1

individual as required by 10 CFR 20.405.

l During routine th roid c nt on the mornin of Friday, July 2, 1971, A6 o

in I

l showe a t

thyroid burden of 1.49 x 0.14 microcurie o iodine n the thyroid.

Subsequent thyroid counting of this individual on July 6 showed 1.14 x permissible; on July 7, 1971, a thyroid count of 97% was found; and on July 8, 1971, a thyroid count of 90% was found. Subsequent daily thyroid hoved the thyroid burden to be reduced to 10% by July 28, 1971.

thyroid burden for the seven consecutive days of July 2 through 4

y 8, 971, was, therefore, an average of approximately 1.24 x 0.14 microcuries. Don Soldan advised during this inspection that Mallinckrodt had interpreted seven consecutive days as taking place in one calendar week rather than any seven consecutive days; therefore, the numerical average, by calendar week, was not excessive and as a result, was not reported as required by 10 CFR 20.405.

It was clearly explained to Soldan by E. C. Ashley during this inspection that the thyroid gland does not know of the existence of calendars and the presence of iodine in the thyroid gland in excess of 0.14 microcuries, averaged over any seven consecutive day period, is considered by Region III as excessive thyroid burden, which constitutes noncompliance with 10 CFR 20.103 and is reportable under 10 CFR 20.405(a) and (b).

J l

Cen W. Roy December 27, 1971 The fourth item of noncompliance concerned the failure of the licensee to maintain records of an evaluation of personnel exposure.

In this instance, two air samplers in the resultsof1.33and1.65x9x10gualityControlDepartmentshowed microcuries per m1, respectively, during the week of July 29 to August 5, 1971. Although it was deter-mined by interview with licensee employees in the QC Department and the Health Physics Unit during this inspection that time weighted personnel i

exposure evaluations were made to show that no one was exposed to excessive concentrations of iodine 131, no records of these evaluations were available for inspection, contrary to 10 CFR 20.401(b).

The fif th item of noncompliance concerned the failure of the licensee to submit reports to the Commission and to individuals who have ter-minated employment or work ansignment, as required by 10 CFR 20.408.

The licensee stated during this inspection that a total of 31 persens

/

have terminated employment or. work assignmeit'in the liisnsei'T facill~

, ties in 1971 up to the date of this inspection, and that failure to r

rabmit reports to the Commission or to the individuals was an oversight on their part.

During this inspection, it was noted that the licensee had been steadily reducing the external exposures to individuals. A review of personnel

, monitoring records showed that during the second and third quarters of

[ 1971, the maximum whole body exposure to any individual has been l

approximately 2 rem per, calendar quarter. Also, with the exception of the one person noted above, thyroid counting data showed that during the period May 1 to December 3, 1971, only two or three persons have l

exceeded 50% of 0.14 microcuries averaged over any seven consecutive days.

I During the Summer of 1971, the licensee made extensive modifications and improvements to their air handling systems which has resulted in L significant reductions in air effluents. These modifications also included the construction of one inch thick Jead walls around the filter bank housings which serve the hot cell and have resulted in a significant reduction in radiation levels at the boundary of the licensee's facilities.

(Paragraph 8)

Licensee Action on Previously Identified' Enforcement Matters The last previous reinspect'on was conducted on May 10 - 14, 1971. The licensee was cited for fe:t items of noncompliance in a letter from the Division of Compliance, Headquarters, dated July 28, 1971. The licensee responded to this letter in a letter dated August 13, 1971. During this inspection conducted on December 6 - 9, 1971, each of the previously noted items of noncompliance were reviewed as to licensee action. These itsas and corrective actions are noted below:

A.

10 CFR 20.105(b)(2) - Excessive radiation levels during January and February 1971 on an unrestricted roof of a building across from the licensee's facilities.

This item was corrected by the licensee moving his vaste handling crea prior to the inspection of May 1971 and the modification of the air handling system on the roof of the licensee's Building 100, including shielding, following the May 1971 faspection.

B.

10 CFR 20.201(b) - No stack sampling was performed of the Building 300 Dispensing Lab laboratory exhaust during January 11, 1971, to May 11, 1971.

It was noted during this inspection that stack sampling at that location began on May 11, 1971, and stated in the licensee's August 13, 1971 letter.

l l

, i 10 CFR 20.201(b) - No inplant air sampling was performed in Building C.

300 dispensing laboratory during January 11, 1971, to May 10, 1971.

The licensee's August 13, 1971 letter advises that air sampling was begun at that location on January 11, 1971, using portable air samplers, and later added to the in-house air sampling system.

I Records reviewed during the inspection of December 6 - 9, 1971, showed that temporary portable air samplers wdre used in the Dispensing Laboratory of Building 300 on January 11 and 12, 1971.

Also, permanent air sample stations were' begun there on January 20, 1971.

D.

10 CFR 20.201(b) - The licensee performed inadequate evaluation of high TLD results, re Item A above.

The licensee's August 13, 1971 letter advised that the TLD results

.were received from the supplier too late for them to act on this i

matter.

It is noted that this problem resulted from the licensee's

, dismantling and moving of their waste handling area and the necessity i

to make the filter change during the period in question due to a Mo-99 processing problem which caused a high radiation level at the absolute filter on the roof of Building 100.

Unresolved Items: None Status of Previously Reported Unresolved Items: None reported.

Unusual Occurrences: None Persons Contacted The following Mallinckrodt/ Nuclear personnel were contacted during the inspection:

Norman E. Drissell, Director of Operations Donald W. Soldan, Supervisor, Radiological Protection Department (Health Physics) and Chairman of the Isotope Committee i

Ralph Nuelle, Group Leader, Health Physics Warren Fadling, Group Leader, Health Physics Robert Wester, Technician, Health Physics Robert Ament, Special Warehouseman (Building 300 Shipping Area)

Mrs. Diane M. Duvall, Technician, Quality Control Department Robert Granger, Jr., Technician, Production Department l

, Management Discussion The following subjects were specifically discussed with Messrs. Drissell and Soldan on December 9, 1971:

A thyroid burden of greater than 0.14 microcuries of iodine 131 averaged over seven consecutive days to one individual and failure to report this to the Commission and to the individual. It was noted that they inter-preted seven consecutive days as taking place in one calendar week rather than any seven consecutive days, therefore, the numerical average by calendar week was not considered excessive and as a result was not reported.

(Paragraphs 5 and 6)

Failure to maintain records of results of an evaluation of personnel exposure. It was stated that normally, records of these evaluations are maintained, but somehow this was overlooked this time.

(Paragraph 7)

Failure to submit reports to the Commission or to terminated individuals as required.

It was stated that this was an oversight on their part.

l 97% was found and on July 8, a thyroid count of 90% was found.

Subsequent daily thyroid counting showed the thyrofd burden of this person to be reduced to 10% by July 28, 1971. The thyroid burden of this individual for the seven consecutive day period July 2 through July 8, 1971, was, therefore, an average of approxi-mately 1.24 x 0.14 microcurie, This individual was interviewed alone on December 7, 1971, regarding this July 1971 occurrence.

It was said that no work was performed before the routine 8 a.m. thyroid counting on July 2.

The individual was performing a triolein and oleic acid iodine 131 on July 1, 1971, in a glove box. The individaul remembers using hot tap water from a nearby sink to get hot water to be placed in the glove box for part of this prep work. The individual thinks the sink must have been contaminated with iodine 131 when the hot water splashed causing contamination to the face and head. This individual stated that upon leaving the laboratory area, no contamination was detected on feet, hnnds, or general body area according to this person. On the morning of July 2,1971, af ter the high thyroid count, head decon-tamination was accomplished.

This individual stated that instructions have been issued to prohibit the use of hot water in this method and also that any sink to be used in the laboratory area must have a prior survey.

The individual's statement generally agrees with information gathered from Health Physics personnel.

The exposure of the above referenced individual to excessive con-centrations of iodine 131, as evidenced by thyroid gland counting, constitutes noncompliance with 10 CFR 20.103(a).

Reports of Personnel Exposures The licensee had not, up to the date of this inspection, reported the overexposure of the person, noted above in Paragraph 5, to the Commission or to the individual which constitutes noncompliance with 10 CFR 20.103(a) and (b).

The licensee did not consider the individual's high thyroid count as a reportable overexposure because they considered " averaged over seven consecutive days" as meaning seven consecutive ca?endar days (Monday through Sunday).

It was clearly explained to the licensee that the thyroid does not know of the existence of calendars and that the

Records of Personnel Exposure Evaluations During the week of July 29 through August 5, 1971, two air samplers in the Quality Control Department showed results of 1.33 and 1.65 x 9 x 10-9 microcuries per al, respectively. Although it was deter-mined during this inspection that personnel exposure evaluations were made to show that no one was exposed to excessive concentrations of iodine 131, no records of these evaluations were available for inspection which consititutes noncompliance with 10 CFR 20.401(b).
