Attached are the aanlytical results for liquid sesqples conectedduring the inspecties of the subject licensee ca June 8-9, 1964.The inspostion ins enmeluded with an .wrelately aceplev,ed fbrinABC-591.

As noted in time zugest of the inspection ocadmeted an Espeuber 27-29,1962, and Jammary 15, 1963, the licensee's samlytical procedure foranalysis' of the *mf11mps pond effluent discharge am11md for filtrationat the first step to remove any suspended solids. The rammining stepsin the analysis are reportedly the same as the c{ ;" J. used by Claude-

Sill of the Aanlysis Brusseh, ID. As a check on this procedure,'twoefflamat discharge semples were conected. One semple (Semple No. 1in the at+N table) was aanlysed by the standard method used bySin, i.e., adding dilaat.e nitric acid as the first step for dissolutionof the readily hydrolyseble thorium and redissa. The second sample(Semple No. 2 in the table) was first filtered by Bill and then thefiltrate and residue solids were each analysed for Ra-226 and Th-230.

As a basis for wison, the licensee's analytical results for thefirst three e of the year are also listed. Pentape it is verthacting that, while the liesasee performs an aanlysis of the solidresiduos obtained 21 ram the filtration, the results reported to theCemanimaion by letter dated Jaaaary 28, 1964, imelule only the datafbr the filtrate.

You vill note that the Pb-210 result for the tailings pond eff1mntsliEhtly exceeds the permissible concentration of 1210#pc/cc. Thelicensee, of course, has not performed Pb-210 or Po-210 analyses.

Please contact us if you have any questions regarding the analyticalresults.

samplers during the entire operstlos and that the semplers were frequentlychecked to assure that the collection ability of the sameplers was not adverselyaffected by butid-up of material on the collection media.

k should be acted that, with the exception of asters! uranium, the concentrationsof the various teetopes la the barren raffinate, as reported by ID, are in excessof'the AEC lisants for average samual release of these isotopes in the solubleform. Deze is a significant variance la the enacentrattoms of Ra-226 and%-230 as soposted by ID sad the licensee. His varisace is probably a directresult of a diftssemos inrID's and the licensee's analytical procedures. Priorto smalysis of a sesspie, the ID procedure calls for achlttication of the samplewith a 2% oolantes of IICL (page 9, " Determination of Radium 226 and narium-

230 la Mill stammamem", by Ebersole, et aQ whereas, Mr. Bety reported thatprior to analysis they filter the sample. Mr. Bety stated that their rationalefor filtrattas is based en their laterpretatloa of "solubt!!ty" as meaning soluble

,

la the carrytag fluid. We predor the ID technique because it is our optalon that"solutdlity"is defined as belag soluble in human body fluids and acktification

f3 with dinnes hcl woodd be more representative of the process whleh takes pieceD in the inunas gut.

Operations at the sut$ect licensed facility were terminated on March 1,1965,thestfore, additlemen saanples are not sva11able. A citation for release ofconcentrations of Ita-223. -224, and -226. n-228 and 282, Pb-210 and Po,210la excess of the le CFR 24 Appsedix R, limits is not applicable based on therosatts of a single asseple bocesse concentratiots may be averaged over aperiod of one yaer (IS CFR 20,106(b)). A citarlos for noncompliance withcondities No. i2. A.(2) et the anbject license is warranted; however, becausethe subject licensed facility is ao longer la operatica we feel that this citationwould serve no useful purpose.

Based on Mr. McCormick's statement during the inspection, that they had not I

processed Alaskast are since the previous inspection, the concentrations of%-232, n-228 and Ra-224 in the barren raffinate were surprising. However,Mr. Daty stated that during the process of scraping the ore pads prior todecoinmisatosing they had probably uncovered some previously unprocessedAlaskan ore. It should be acted that the licensee was processing the scrapngsfrom the ozw pode at the time the barren raffinate sample was collected.
