ICPP, Idaho Chemical Processing Plant

The conceptual design and operation were stated to be based on experiences AEC has accumulated in its operations. 7 In fact the design was based on the ORNL pilot plant concept incorporated in the Idaho Chemical Processing Plant which cost about 20 million TOE was based on experiences at Hanford and SRP in plants that cost about 100 million. The TOE for the ICPP was not 80%, but 3%8,and there were major safety deficiencies. 

An interesting application of emissions control catalysts occurs in management and inmiobilization of spent radioactive fuels and wastes in the nuclear industry. During nuclear waste processing (NWP) at the Idaho Chemical Processing Plant (ICPP) NOx (NO and NO2) and CO pollutants are typically discharged at levels of 1-3% to a waste gas stream. It is necessary to control both NOx CO emissions in order to comply with current and anticipated regulatory requirements. 

The Idaho Chemical Processing Plant (ICPP) soluble poison meter was developed as an instrument to monitor continuously the amount of nuclear poison entering non-geometrically safe process vessels for dissolution of spent nuclear fuel elements. The nuclear poison (gadolinium or boron) is added to the dissolver with the dissolving acid. The meter detects the poison concentration with an accuracy of il%, including errors resulting from calibration, analytical techniques, drift, and statistical... 

In the reprocessing-of highly enriched uranium at the Idaho Chemical Processing Plant (ICPP) corrosive concentrated uranium solutions are generated from process upsets, custom processing, and sample residues. A study was performed to determine an alteriiatlve critically safe storage c -stem to the one in present use for these solutions, .- ... 

Moderation control in operations with fissile material makes some proposals technically feasible and can result in significant cost savings in others. Often designs can be simplified and processes made more efficient. However, there are many problems and pitfalls both in calculations and implementation. Therefore, current criticality safety philosophy at the Idaho Chemical Processing Plant (ICPP) permits moderation control only within shielded facilities capable of containing the consequences of an accidental criticality. This requirement was imposed midstream in the development of several projects and necessitated Some redesign. I will discuss... 

Reprocessing of highly enriched irradiated reactor fuel at the Idaho Chemical Processing Plant (ICPP) presents significant problems to the Criticality Safety (CS) and Safeguards Security (S S) Sections. Two major interactions between these sections occur when irradiated fuel is stored and fuel b dissolved. 

This paper discusses how the safe U mass and boron limits were determined for toe zirconium fuel dissolver at the Idaho Chemical Processing Plant (ICPP). This vessel, which has a S08-mm (20-in.)-o.d. cylinder with a complicated internal structure (Fig. 1), uses borated hydrofluoric acid to dissolve highly enriched uranium-zirconium alloy fuete.
