Discover the revolutionary REACh™ system for low-level waste characterization and classification. By measuring gamma dose rates and gamma emitting activity, REACh™ provides quick and accurate results. With waste stream specific scaling factors from the RADMAN™ database, even hard-to-detect nuclides are accounted for, ensuring complete characterization and classification in a single step. Trust REACh™ for efficient and precise waste management solutions. Unlock the Potential - Embrace the Future The REACh™ Detector System revolutionizing LLRW Waste Package Characterization - Where Accuracy Meets Efficiency! An Innovative Step The REACh™ System signifies an advancement in the way low-level waste is characterized and classified. By directly measuring gamma dose rates and gamma emitting activity of radionuclides, the REACh™ System can provide rapid and precise characterization results. This is made possible through a fully integrated system involving the REACh™ Detector and the RADMAN™ industry standard radwaste management platform. The detection of hard-to-detect radionuclides (e.g., H-3, C-14, Tc-99, TRUs, etc.) is achieved by utilizing waste stream specific scaling factors from the RADMAN™ database, thus enabling comprehensive characterization and classification in a single straightforward process. The Challenge Overly conservative results can significantly increase the costs associated with packaging, transporting, and disposing of the waste. Current methods for characterizing low-level radioactive waste rely on rough approximations that often lead to overly conservative results. To reduce cost and determine disposition alternatives, more accurate methods are necessary. The current regulatory guidance for characterizing Dry Active Waste (DAW) is hardly representative and the inaccuracies of this method are compounded by the practice of compositing the swipes over time prior to analysis. This leads to an underestimation of short-lived radionuclides, which are typically found in low-level radioactive waste (LLRW). When dose-to-curie conversion techniques are utilized and hard-to-detect radionuclides are estimated using scaling factors relative to Co-60 or Cs-137, underestimating the short-lived gamma emitters results in an overestimation of the hard-to-detect radionuclides, as well as Co-60 and Cs-137, since the majority of the dose rate is attributable to these two radionuclides. Reliable and efficient real-time radionuclide concentration data is crucial during the processing of nuclear waste at commercial power plants. Our Solution The REACh™ Detector system is the solution that has been developed to provide a fast, accurate In-Situ Characterization as compared to what is currently available. This Solution has been designed to save the user time with instantaneous readings, thus minimizing dose with an ALARA conscious solution, and minimizes potential human errors with the integration of both software and hardware.

< Back An Interview with our founder, Peter Tuite Dec 2, 2021 We sat down with Peter to ask him some questions about the industry, how he got his start, and more. What made you decide to start your own nuclear engineering company? Because, I had some skills that I thought could be applied. And you got to remember, when we first started, we did hazardous waste as well as nuclear waste. I had a partner, Bob, when I started, but it didn’t last very long. What were some of the biggest challenges you faced early on? Money. The first year, we went through 100k at the bank, and they called the note. That’s when Bob decided to go back to teaching (laughs) and we paid the bank off, and then I was on my own. How did RADMAN come into development? Well, I was involved in writing Part 61 before I started WMG. So, I worked with the guys at the NRC, and they had just instituted the topical report deal. So, I figured we’d put something together and submit a topical. The original RADMAN ran on a TRS 80 computer and included a dot matrix printer. What are some of the biggest changes or trends you’ve seen happen in the industry since you started WMG? There’s not much money to spend. Utilities are spending less money, there’s a larger focus on economics than there was before. Remember, they used to be able to just get automatic rate increases, which is no longer the case. And the guys in Radwaste are still pretty low on the totem pole. They don’t get the recognition in the industry that they deserve. When the NRC first started auditing plants, the guys in Radwaste had a lot more clout internally because nobody wanted to have conflict with the NRC. That is no longer the case. What is the most interesting customer support call you have ever received? (laughs) Wow. I won’t name the plant, but I trained them. In those days we used to send the code on about 5 floppy discs. And I got a call from one of the guys I trained, he was having problems with the new release. He said something along the lines of “I can get 3 of the discs in the drive, but I can’t get the fourth one in!!” What achievement are you most proud of? The longevity of the company. For it to have lasted so long, and to now have passed it on to my son. What advice do you have for younger engineers who are just starting out? Put in the time and know the subject better than anybody else you deal with. Be the smartest person in the room on the subject at hand. Where would you like to see WMG in another 10 years? (laughs) Around. I’d like to see us keep doing what we do, continuing to excel in engineering and software. Previous Next

< Back NUREG BR-0204, Revision 3 Update Oct 5, 2020 WMG Update Notification and Timeline of the NUREG BR-0204, Revision 3 Implementation On June 30, 2020, the Nuclear Regulatory Commission (NRC) published NUREG/BR-0204 Revision 3 titled Instructions for Completing the U.S. Nuclear Regulatory Commission’s Uniform Low-Level Radioactive Waste Manifest . On July 2 they made notice of this publication in the Federal Register , stating that, “Revision 3 and its forms became effective on July 2, 2020. Use of the NUREG/BR0204, Revision 2 forms should be discontinued on or before September 30, 2020.” This release caught many stakeholders by surprise, some of whom had been commenting and working with the NRC on the development of the revision. Of particular concern was the relatively short 3-month suggested implementation period. Multiple utilities requested the Nuclear Energy Institute (NEI) to ask the NRC to delay the implementation of Rev 3 of the 540/541 forms beyond the 9/30 date. On September 14, 2020, the NRC held a Webinar titled Implementation Status of NUREG/BR-0204, Revision 3, and Associated NRC Forms . Based on discussions and input from stakeholders, the NRC agreed to publish a notice in the Federal Register soon after evaluating an extension to the implementation date. Stakeholders and the NEI suggested a date of 3/31/2021. For the near future, the NRC has indicated that they would be willing to “exercise enforcement discretion” so that no one would be cited for using Revision 2 beyond the 9/30 date. The preface of NUREG/BR-0204 Revision 3 states that the changes from Revision 2 include: Updated instructions to reflect changes to the Uniform Manifest Forms. Updated references to U.S. Department of Transportation (DOT) regulations to reflect the current DOT regulations. Additional discussion on the reporting of inventories based on lower limit of detection values, the potential use of indirect methods to determine these inventories, and the use of indirect methods in waste classification calculations. Clarification of the intent of the certification statement on Form 540. Overall improvements to the clarity of the document. As with many things nuclear power related, “the devil is in the details”. Changes to the forms include page size, layout, the title of numerous columns, and minor formatting changes. The methods for annotating that a nuclides inventory is based on a lower limit of detection (LLD) value has changed, including the addition of a # symbol to indicate if that value was determined by “the use of indirect methods”. The revised certification statement will now consist of a statement based on the DOT’s certification statement required by 49 CFR 172.204 and statements based on the NRC’s certification statement required in 10 CFR 20, Appendix G, Section II. On September 30th, the last day of the original “grace period”, NRC published an update in the Federal Register stating, “Use of NUREG/ BR–0204, Revision 3 has been delayed. Until further notice, licensees should continue to use NUREG/BR–0204, Revision 2 and the versions of NRC Forms 540, 541 and 542 that were renewed in January 2020, or equivalent, as defined in NRC’s regulations.” WMG is working on inclusion of compliant NRC 540/540A and 541/541A forms in the RADMAN™ suite. We will likely be “holding” that software release, Version 9.5, pending further guidance from the NRC about an updated implementation date. Until then, we are working on a revision to the RADMAN™ software (version 9.4.2), targeted for release by the end of October, that will have the updated 2020 Emergency Response Guides in addition to the January 2020 Uniform Waste Manifest.
