Basic surface-water and precipitation data collected from June 1961 through June 1965 at 10 stations in Lower Little Creek basin of Lamar and Marion Counties, Mississippi, are presented. The U.S. Atomic Energy Commission's Tatum dome site of Project Dribble is in Lower Little Creek basin. The data show a 3.80-inch deficiency in precipiation in the Tatum dome are from April 1964 through June 1965 and an 11.72-inch deficiency from June 1961 through June 1965. The mean monthly discharge at Lower Little Creek (4892.40) was less than the median monthly value during 11 of the 15 months from April 1964 through June 1965. Chemical analyses of water samples collected from five streams in the Tatum Dome area indicate that the water is of generally good quality; for example, dissolved-solids content ranged from 16 to 23 parts per million for samples collected during the period from October 31, 1961, through October 23, 1964. 4 figures, 4 tables.

The completion of Phase III construction in B Plant will provide facilities to meet certain common needs of departmental Waste Management and Fission Product programs. This is an estimate of the total and unit costs of operation in these facilities on a `goin concern` basis, recognizing full well the highly tentative nature of information available with respect to staffing, process rates, equipment, etc., approximately 3 to 4 years in advance of operations. It is planned that this document serve as an operating cost guideline during the interim period, subject to periodic revision as more firm data of significant cost impact becomes available. This review covers those functions performed within B Plant proper plus a PAW feed material preparation function tentatively planned for Purex head end for convenience purposes. Feed material streams from supernatant and sludge removal functions are considered F.O.B. B Plant. No staffing or costs have been included for tank farm activities or the 200 North storage function. Cesium and strontium costs include processing to a solid and packaging in a high integrity container compatible with final confinement requirements. Staffing is provided to perform a peroxyacetate strike or similar function for the cerium-rare earth fraction, but additional study would …

The incentives, objectives, and previous test results of the hot-die- sizing program have been presented in recent documents. The test described in this report is one additional step in the evaluation of an alternate fuel fabrication process.

This document provides details of the Report to the FEDC Working Committee for the period of January to April 1966. N-Reactor fuel development and production is discussed.
