Project 74-1-a Additional facilities, high level waste storage, Savannah River, South Carolina
$6,000,000 This project provides for the installation of four additional high level waste storage tanks, a high level waste evaporator, and associated waste transfer piping in the waste storage tank farm serving the F chemical separations plant at Savannah River.
Initiation of this project in FY 1974 is necessary in order to provide additional waste storage and evaporation capacity in the F area by early FY 1977, when existing capacity in the F area will be fully utilized.
The $6.0 million dollars for FY 1974 will be required for design, construction, including excavation, procurement of steel, and general procurement of auxiliary equipment for the waste storage facilities. The net increase in operating cost is expected to be about $200,000 per year.

Savannah River F chemical separations area. Project 74-1-b Replacement ventilation, air filter, This project provides for construction of a replacement sand filter for ventilation air exhausted from the F Area chemical separations production facility. The proposed new sand filter will be contained in a concrete enclosure currently envisaged The filter bed will consist of evenly distributed and stratified layers of sup- to be 360 feet by 100 feet by 18 feet deep. Air supply and return tunnels will also be provided. porting materials and filter media.
The design basis for the current estimate of cost includes a concrete structure containing a bed of graded stone and sand approximately 8 feet thick, an air distribution system of corrosion resistant materials, and an air velocity through the Because of the observed deterioration in the existing filter structure on the inlet side (pre- filter of 5 feet per minute. sumably due to acid corrosion), changes will be made in design and materials of construction to minimize such deterioration The four existing exhaust fans will be modified to operate at higher speeds and will be equipped with in the new filter. higher horsepower motors. The normal electric power supply for the new motors will be increased in capacity through instal- lation of a new transformer.
It is necessary to filter the exhaust air from a chemical separations (fuel reprocessing) plant in order to protect the envi- ronment against particulate releases of radioactivity into the plant ventilation system due to accident or process upset. Initiation of this project in FY 1974 is required to assure continuity of production in the F chemical separations area be- cause the bed support members of the existing sand filter in the area of the air supply laterals are progressively deteri- orating, and because the pressure drop through the filter bed has doubled since initial operation in 1954. The F Area sand filter is approaching the end of its useful service life. Research and development on this project is estimated to be $100,000, of which $40,000 and $60,000 will be used in FY 1973 and FY 1974, respectively. Details of Cost Estimate:*

Project 74-1-c Calcined solids storage and plant safety improvements Idaho Chemical Processing Plant, National Reactor Testing Station, Idaho
This project provides at the Idaho Chemical Processing Plant (ICPP), National Reactor Testing Station, for (a) additional waste solids storage bins to contain highly radioactive solids from the Waste Calcining Facility (WCF), (b) the relocation of eating facilities away from process areas and (c) the modification of the main building entryway and employee change room to improve contamination control and prevent the spread of contamination.
The waste solids storage addition will consist of a concrete vault, largely below grade, containing stainless steel bins in which highly radioactive calcinèd solids will be stored, and two small, separate, enclosed rooms one for instrumentation, and the other to house a cyclone separator and block valves in the transport air system. The solids storage addition and all associated utilities and transport air system will be integrated into, and will be compatible with, the existing WCF and existing solid storage facilities. The design will include provisions for retrievability of the calcined wastes.
The plant safety improvements will include: (1) constructing either a single story, pumice block, multipurpose building or an addition to the chemical processing plant facility to house the cafeteria-lunchroom, operator training center, and a few administrative offices, and (2) expanding the employee change room with modifications of the main building entryway to improve the separation of "clean" and regulated areas for minimizing the spread of contamination.
Vacated space in the existing eating area will be converted into engineering support offices to help alleviate overcrowded conditions now existing; cafeteria equipment, now in the existing eating area, will be relocated to the multipurpose build- ing location. All utilities for the buildings, primarily water, steam, and electricity, will be provided from existing sources.
Initiation of this project in FY 1974 is required to provide additional solids storage facilities to contain calcined solids resulting from operation of the WCF. Existing solids waste storage facilities will be filled by the end of FY 1976. In addi- tion, modification to the ICPP facilities are necessary to update them to present contamination control standards, as well as to provide improved support facilities to meet current stringent standards for contamination control and personnel protection.
