A professional who operates remote-controlled equipment in hot cell to conduct metallurgical and chemical tests on radioactive materials. Responsibilities include:

• Controls slave manipulators from outside cell to remove metal or chemical materials from shielded containers inside hot cell and places on bench or equipment work station.
• Tests chemical or metallurgical properties of materials according to standardized procedures, and observes reaction through cell window.
• Sets up and operates machines to cut, lap, and polish test pieces, following blueprints, x-ray negatives, and sketches.
• Tests physical properties, using equipment, such as tensile tester, hardness tester, metallographic unit, micrometer, and gauges.
• Immerses test sample in chemical compound to prepare for testing.
• Places irradiated nuclear fuel materials in environmental chamber to test reaction to temperature changes.
• Records results of tests for further analysis by engineers, scientists, or customers.
• Places specimen in shielded container for removal from cell, using manipulators.
• Participates in cleaning and decontamination of cell during maintenance shutdown.
• May devise adapters and fixtures for use in hot cell operations.
