Sampling Glove Boxes

The sampling glove boxes developed and manufactured in 2021 make part of the TUE re-extraction facility for the the Fabrication/Refabrication Plant (FRP) of the Pilot Demonstration Energy Complex (PDEC) at the Siberian Chemical Combine (SCC). 

The dry precipitate glove box is designed to receive dry powder, take samples, weigh samples and discharge the powder for further storage.

The glove box equipment includes:

• inlet, exhaust, and maintenance vents,
• TV camera mounting fixtures,
• LED lights,
• negative pressure and temperature measuring transmitters,
• a cyclone dust collector,
• scales.

The glove box design provides the space to install and connect a manual station for sending samples via pneumatic tube capsules.

A bag port to remove decontaminated objects, a drain, a sample outlet, and a container port are designed at the bottom of the glove box. The bag port design provides for attaching plastic bags. A height-adjustable table on the base frame under the bag port facilitates the bag-out of the objects from the glove box. The glove box accessories include a sample carrying container.

A cyclone dust collector with a nuclear-safe catch-pot unified for in-box application in the FRP is utilized for dry cleaning.

The glove box is supplied with a sampling kit, including a sampler, a tray, a scraper, a wide trowel, a narrow trowel, a mortar, a pestle, and a funnel.

The receiving hopper fills a can with dry powder. A sample is taken from the can, and sampled powder is sent in a specialized container via pneumatic tube to the laboratory. Upon the availability of the sample analysis results, the can is loaded into a TUK-30М2 container through the airlock. The container is tightly attached to the airlock to maintain the glove box containment.

Specifications of the dry precipitate glove box:

The sampling glove box is designed to take and prepare samples of the process media from the equipment of the TUE extraction facility to be sent to the analytical laboratory.

The glove box equipment includes:

• inlet, exhaust, and maintenance vents,
• a transfer airlock to connect to the dry precipitate glove box,
• an antechamber to post in the tools and chemical agents,
• negative pressure and temperature measuring transmitters,
• a LED light,
• a drain.

Dry cleaning of the glove box is carried out, if necessary, with the cyclone dust collector located in the dry precipitate glove box.

The sampling from the equipment of the TUE extraction facility is remote and initiated by the operator’s command from the local I&C workplace. The liquids from the extracting equipment are fed via the sampling line to the glove box, where the operator takes the samples by manually opening the valves. Then, the samples are sent to the analytical laboratory.

Specifications of the sampling glove box:

The shielding wall is mounted in front of the glove boxes and receiving hopper to protect the personnel against ionizing radiation. The thickness of the biological shielding is 40 mm of steel and 20 mm of polyethylene. The windows are made of ТФ 5 plate with a thickness of 36 mm and polycarbonate panel with a thickness of 10 mm. The height of the shielding wall is 2 meters from the floor level. The shielding below the table level is sliding to provide access to the space under the box.
