Perma-Fix has been developing technologies for the nuclear waste industry for decades. Our staff possess a broad range of skills across numerous disciplines that give us a real advantage in developing new waste treatment technologies.

Our latest innovation, the Pump and Purge system is a unique and innovative treatment technology for tritium oxide. Utilizing a vacuum/suction process and air with both naturally occurring moisture content and saturated moisture, contaminants are cleared from system equipment and piping, allowing those systems to be shipped without removing them from the associated skids. Newly developed custom software precisely tracks pumping activities to accurately monitor contaminant levels.

This system was custom designed to remove legacy tritium from the Princeton Plasma Physics Laboratory with a goal of reducing the risk of a release and safely disposing of contaminated materials. Perma-Fix serves as the technical expert for this project, providing project management, characterization, and material disposal services. Project commenced in October 2021 and is scheduled for completion in winter 2023.

How It Works

During the pump/purge process, the amount of tritium removed will be measured by capturing the flow rate and tritium content of the vapor stream exiting the System in one second intervals and automatically calculating the total tritium in that interval. The intervals will be continuously summed to determine the quantity of tritium that the molecular sieve bed has absorbed since it was placed in service. The molecular sieves are specifically designed to absorb water or any moisture in air. Pumping pressurize moist air into systems is used to soak a system and release more tritium oxide from internal surfaces. After soaking, the system can be used to pull a vacuum on the same system.

The pump/purge equipment will be connected to an identified piping/equipment System at locations that promote flow through the System. Those connection points could be existing connection points, line breaks or, in most cases, “hot” taps that create openings to the larger (2” ‐ 3”) piping. The “hot” tap consists of a fixture that is attached to the pipe, typically by clamping, that contains a sealed drill bit and an inlet/outlet port. There is a ball valve installed on the port. Once the connection points are established, the pump cart is attached to the inlet port and the purge cart is attached to the outlet port. Valves in the System between the inlet and outlet ports are aligned open (usually manually) so that air can flow through all portions of the System.

Once an acceptable tritium removal rate is achieved, the pump/purge equipment will be disconnected from the System. Swabs will be used to collect smear samples from the inside of the piping on the inlet and outlet connections, accessed through the ball valve on the connection. Those smear samples will be analyzed, and the results used to determine if the System can be shipped (a separate procedure governs the determination of shipping suitability). If the System does not meet shipping requirements, a repeat of the pump/purge process may be initiated, or encapsulation of the piping interior will be employed. Throughout the process, localized ventilation will be established at any breach point, connected to the building ventilation System. In addition, local tritium monitoring will be established in the room. If an alarm sounds, valves will be closed, and the pump/purge System will be shut down.

pps demonstration pps demonstration

The total tritium that each molecular sieve bed processes is tracked and, at a predetermined total (typically no more than 540 curies per bed), the flow from the System will be switched to the second installed bed. The first used bed will be removed, and a new bed installed as a separate activity. During System operation, breakthrough of tritium past the bed will be monitored intermittently on the exhaust from the molecular sieve bed or vacuum pump discharge.

Other Applications

Perma-Fix is actively evaluating other applications for the Pump and Purge system for any projects or systems with high amounts of air borne contamination. Alternate filtration media is being evaluated for non-aqueous form contaminates. Applications may include reducing air borne contaminates in glove boxes, hot cells, or pump houses prior to entry or servicing. This technology can be adapted to serve the needs of the oil and gas markets as well as treatment of hot cells. Contact us today to learn more.

"It goes beyond just the technology -- at Perma-Fix we deliver turn-key solutions."

In spring 2020, Perma-Fix debuted Perma-Sort, a new automated radiological characterization and segregation system for bulk materials. Drawing on our team of project managers, nuclear engineers, and certified health physicists (CHPs) with more than 50 years of soil sorting experience, Perma-Fix built a customized conveyor-based radiological assay system designed to provide 100% characterization of material efficiently and with industry-leading measurement quality. This innovative system offers management of end-point uncertainty with the characterization of both material exceeding the site acceptance criteria for transportation and disposal offsite and material meeting the site unrestricted release criteria.

How Perma-Sort Works:

Materials are loaded into a large feed hopper and then transported through the system with an electronically controlled conveyor survey belt. While on the survey belt, the material is analyzed and tracked. At the end of the survey belt, the material is transferred to a short reversing conveyor that spins in one direction for below criteria material and in the opposite direction for above criteria material. The reversing conveyor transfers materials to standard stacking conveyors which can then create piles of material or transfer directly to trucks or waste containers.


Supports a Broad Range of Contaminates:

  • Fission Products
  • NORM/TENORM
  • Transuranics
  • Heavy Metals
  • Beryllium
  • UXO/MEC

Perma-Sort Capabilities:

  • Trailer mounted system for simple and rapid mobilization and setup
  • Material output can be discharged into virtually any container size or managed with multiple takeaway conveyors
  • Capable of processing > 200 tons of bulk materials per hour
  • Industry leading radiological measurement quality
  • Operating software supports multiple material profiles for varying bulk material types
  • Automated reporting supports MARSSIM and FSS objectives as waste disposal objectives such as profiling and waste disposal
  • Abundant guards, railings, remote e-stops, and keyed lock-outs ensure safety for system operators and near-by support staff
  • Material is processed with minimal effluent and noise emissions

Mercury Almalgamation

Leverage Our Extensive Experience with Elemental Mercury Disposition

Mercury of various forms have been widely used throughout the U.S. and internationally, and to date, more than 600,000 pounds of this radioactive waste co-contaminated with mercury have been processed by one of Perma-Fix's many treatment technologies. Perma-Fix has implemented treatment solutions based on available and patented technologies to address these problematic wastes.

Perma-Fix provides effective treatment of radioactive-contaminated elemental mercury via amalgamation, the required treatment method for these wastes. Perma-Fix employs a patented amalgamation process using proprietary reagents that meet the EPA technology treatment standard (AMLGM). This process treats elemental mercury waste to meet the requirement of AMLGM using chemical reagents that bind the mercury and render it non-leachable. Mercury treatment is provided in a dedicated area of the facilities, with its own air handling and filtration system, for treatment of large volume, mercury contaminated wastes (elemental) using a proprietary amalgamation and stabilization process.
