An experimental program (Project Cleer) was initiated to investigate the heat transfer characteristics of a surface covered with a wick-like material and cooled by a capillary liquid. The preliminary heat transfer analyses developed and the measuring equipment and methods to be used are discussed. (LCL)

The purpose of this report is to provide a basic working tool for determining the relationship between the allowable temperature increase within the Columbia River reach at the Hanford Site and the actual temperature increase as associated with various reactor operating modes. This basic tool can be utilized for day-to-day operating purposes or for the achievement of historical information.

The annual report on the previous fiscal year`s accomplishments attributed to process development has been provided about six months after the end of the fiscal year. In accordance with a recent request, the date of this report has been advanced to coincide with the end of the fiscal year. Further, the scope of the report has been expanded to include a narrative assessment of program accomplishments. Because of this enlargement of scope some liberty has been taken in identifying new products and development gains. The Douglas United Nuclear process development program can be categorized into the following: (1) Cost Reduction, (2) Increased Plant Life, (3) Versatility, and (4) Safety and Licensability. The overall program goal is to develop technology that will provide greater efficiency at reduced cost and yet be responsive to an increasing variety of product requirements while continuing the excellent plant safety performance. The goal is significant when considered in view of increasing budgetary pressure. The projected defense requirements after 1975 are not expected to require the full capacity of the Hanford reactors. However, based upon the anticipated growth of electric power requirements and space exploration power requirements, the current full productive capacity of the Hanford reactors will …

The following is all the information the authors can get on the graphite bar history from the A and G test holes at C-Reactor. The A test hole was charged with 18--23 1/2 inch long graphite bars before the original startup of C-Reactor. This was 6/12/53. On 9/21/63 seven of the graphite bars were discharged. Position {number_sign}18 thru {number_sign}12. Positions {number_sign}11 thru {number_sign}1 are still in the reactor. Data on the seven bars discharged and the eleven bars still in the reactor is given. On 7/21/59 a 2-foot section of tube block was removed from the G test hole. This tube block had received 15,462 MWD/AT at time of discharge. On 4/21/60 three solid graphite bars were removed from the G test hole. These bars received a total of 18,642 MWD/AT. There are six more bars in the G test hole. They are in positions 1 thru 6. The approximate total exposure is given.

This report presents the details of the activities of Douglas United Nuclear at the Hanford site during the month of May 1968.
