Recovery of uranium and plutonium from Redox off-standard aqueous waste streams

Recovery of uranium and plutonium from Redox off-standard aqueous waste streams

Date: December 31, 1949
Creator: Holm, C.H. & Matheson, A.R.
Description: In the operation of countercurrent extraction columns as in the Redox process, it is possible, and probable, that from unexpected behaviour of a column, operator error, colloid formation, etc., there will result from time to time excessive losses of uranium and plutonium in the overall process. These losses will naturally accumulate in the waste streams, particularly in the aqueous waste streams. If the loss is excessively high, and such lost material can be recovered by some additional method, then if economical and within reason, the recovered materials ran be returned to a ISF column for further processing. The objective of this work has been to develop such a method to recover uranium and plutonium from such off-standard waste streams in a form whereby the uranium send plutonium can be returned to the process line and subsequently purified and separated.

Peroxide process -- 234-5 Building

Peroxide process -- 234-5 Building

Date: October 11, 1949
Creator: Groswith, C.T.
Description: The mechanical line being developed at Los Alamos is designed around the peroxide precipitation process. Development work, at that site, on this process has progressed to the point where actual plant equipment can be designed for future use. The process for converting the peroxide to a reducible fluoride is known. From the reduction step on, no change is necessary in the present process. The possibilities of a satisfactory peroxide process were recognized before design and construction of the R.G. Line, but the development work necessary for this process had not progressed far enough to have been included in that line. The gain to be realized by the adoption of the peroxide method is so great that the amount of work necessary for development of this process can certainly be justified at this time. Advantages of this process are summarized and it is recommended that serious consideration be given to using the peroxide process before design of the R.M. Line goes further.

Determination of slug temperatures for various power levels

Determination of slug temperatures for various power levels

Date: January 5, 1949
Creator: Burda, E.J.
Description: This study was undertaken to determine the maximum temperatures that may be expected in slugs under various operating power levels. Information of this nature is required to properly evaluate the effects on the slug of pile operation at power levels higher than those currently in use.

Four in. three jaw type connector suitable for vertical mounting sample for job 11

Four in. three jaw type connector suitable for vertical mounting sample for job 11

Date: July 8, 1949
Creator: Grubbe, A.C.
Description: As authorized by purchase order No. 11-2532 dated March 11, 1949 of the Kellex Corp., the first sample of a 4 inch three jaw type connector for Job 11 was fabricated. The design of the connector was per Crane Co. drawing DR-25126-D except vertical mounting. The materials were per Crane Co. drawing A-24491-C. As instructed in verbal conversation with Dr. D.D. Jacobus and as requested in Mr. J.J. Cuniffe`s letter of May 6, 1949, and Ingersoll-Rand Company`s 1 1/4 inch 534 impact wrench with suitable socket to fit the hexagon head of the operating screw of the 4 inch connector was procured on loan to make some preliminary tests. Engineering drawings are listed in a second report on the data base.

Material balance flowsheet Redox Production plant

Material balance flowsheet Redox Production plant

Date: June 6, 1949
Creator: Tomlinson, R.E.
Description: The attached material balance flowsheet for the proposed Redox Production plant is based on the two chemical flowsheets submitted by R.B. Richards of the Technical Division in HW 13,320 (INDC-3130) and HW 13,452 (INDC 3176). Production rates for the plant have been assumed as 2.5 short tone U per day (including a maximum of 0.75 short tons of U from stored Bi PO{sub 4} waste) and 19 kg. Pu per month (633 gms/day) as established by the Redox Committee. The flowsheets for preparation of solvent extraction feed from Bi PO{sub 4} waste, as well as the waste treatment systems will be covered in a future document.
