Transmitted herewith are three charts showing the temperatures attained at various points of the slugs in a typical tube of a flat ended pile. These charts are based on the latest information available to us on September 15, 1944. They are valid for any power load when the water rate is 21.0 gpm, whatever may be the inlet temperature of the cooling water. A simple method is provided for correcting the curves for deviations in water rate from 21 gpm. There is appended a detailed explanation of their derivation and of the evaluation of the constants involved in their construction. The current discovery that the pile will be self-poisoned by transient fission products means that the true temperature curves will be somewhat flatter than those here presented.

This barely legible document describes the canning process, B area activities, and the 200 area activities.

Hood Worthington reports that slug testing in autoclaves shows improvement to substantiate a meeting on the initial loading of pile B and production for B.F. Babcock report examining five drafts of Operating Standards for the 100 Area. C.W.J. Wende are considering alternative loading schemes due to the observation that lead dummy slugs at the inlet end of a tube may mushroom when subjected to the stress of discharging. J.A. Wheeler reports on heavy metal content of reclaimed slugs compared to normal slugs. Also, temperature measurements on slugs in 105-B and corrosion rates of heavy metals are given. P.F. Gast reports on safety rod control calculations. T.B. Drew report on volume estimations of the B pile and analysis of data from leakage tests. Lastly, W.K. Woods reports on testing of solid aluminium dummies in the W-tube using an electric needle technique to detect motion of the pieces. Water flow considerations are discussed.

The metabolic properties of the carrier free long lived fission products in the adult rat have been investigated at different intervals ranging from one to sixty-eight days following administration of the radioactive material. The radio elements studied include the most important long lived fission products, namely, Sr, Y, Zr, Cb, Ra, I, Xe, Cs, Ba, La, Ce, Pr, Np, and the unseparated uranium free fission mixture. The routes of administration included intraperitoneal, intramuscular, oral and intrapulmonary. The tissues assayed for the distribution of the administered radio elements included heart, liver, kidney, testes, spleen, muscle, skin, stomach, small intestine, large intestine, bone, blood, lungs, brain, fat, adrenals, lymph nodes. Urine and feces were collected separately at daily intervals for assay. Data acquired is provided in tabular form. For the fission products which were poorly absorbed from the site of both intramuscular arid intraperitoneal injection (namely, Y, Zr, Cb, Ru, La, Ce, Pr, Np, and the uranium free fission mixture) only the intramuscular data are given here and it is expressed in terms of the distribution of the fraction absorbed from the site of injection. For the radio elements which are completely absorbed following intraperitoneal and intramuscular injection or are absorbed in …
