The B&W Technical Services Group, Inc. Hot Cell Facility consists of four independent beta-gamma type hot cells.
The hot cells are connected to each other by transfer ports and a common isolation room. The hot cells are designed to be flexible and allow the interiors to be revamped, when necessary, so work can be performed quickly and at the lowest possible cost. The largest of the cells is connected to a water-filled transfer canal by an access hatch. The transfer canal leads to a 25-foot deep storage pool, which is located in a high bay area equipped with a 25-ton bridge crane for cask handling.
Work in the hot cells since 1985 has consisted of examinations to investigate extended burn-up commercial LWR fuel rods, examination of advanced spacer grid designs (both capsule and full sized assemblies), failed in-core instrument detectors, and failed fuel rods.
Hot Cell Descriptions
- Cell 1 is 16' x 8' x 15' high and has the capability for accepting full length commercial LWR fuel assemblies and fuel rods, and is rated for 300,000 Ci of Co-60.
- Cell 2 is 14' x 5.75' x 15' high, is used primarily for metallography and is rated for up to 6,000 Ci of Co-60.
- Cell 3 is 6' x 4.5' x 15' high and is rated for up to 600 Ci of Co-60.
- Cell 4 is 6.25' x 4.75' x 15' high and is rated for up to 10,000 Ci of Co-60.

Isotope Re-Encapsulation Facility
A shielded clean facility is located in the Cask Handling Area to handle uncontaminated radioactive specimens that must be returned to use in the field. It is used for re-encapsulating Cs-137 and AmBe neutron oil well logging sources. In all, we have re-encapsulated hundreds of gamma and neutron sources. The facility could be used to re-encapsulate other types of sources as well. The stainless steel work area measures 4' wide by 4' high by 12' long, and is divided into three work areas.
Services
The following remote operations can be performed in the isotope re-encapsulation facility:
- Milling
- TIG welding
- Liquid penetrant inspection
- Video inspection / recording
- Decontamination
- Hydrostatic pressure testing
- Dimensional verification
