Hello
Used Fuel Services
TransWare's staff are experts in the management and disposition of fuel once it has left the rector core. With expertise in all of the leading cask designs, loading procedures, and industry requirements, our team is ready to help you with any and all stages of your used fuel management.
Overview
Overview
The strategic handling and disposal of used fuel can be an overwhelming task complicated by fuel histories spanning almost 40 years, a variety of cask vendors, and ever changing loading requirements. Fuel misloadings and tech spec violations can be devastating. Sub-optimal loadings can paint you in a corner and excessive campaign or off-site dose can be dangerous to your staff.
Planning for your first campaign involves many coordinated steps that our team’s experience can help you with immensely. We can help you successfully initialize and complete your first dry cask storage campaign, whether we are helping you chose a cask vendor, develop procedures, or characterize your entire fuel inventory. Based on your specific needs we can help you get on the right path or drive a campaign to completion by incorporating best practices our team has implemented to develop hundreds of successful cask loads. Maintaining a used fuel program can be equally challenging, especially for smaller utilities where sporadic loading activities can pull staff away from other critical work. Frequent cask vendor license amendments can affect your future loads in unforeseen ways. Partnering with our constantly engaged team will help ensure that your fuel is out of the pool and onto the pad without impacting other plant operations.
With more recent focuses on the integrity and full core offload capabilities of spent fuel pools, we’ve focused additional efforts on developing methods to support our industry partners with a variety of spent fuel pool analyses. Gamma and neutron heating sources can affect the integrity of the concrete walls. Long-term exposure of the absorber plates can lead to a loss of their ability to effectively control neutron sources. With advanced in-house and industry standard methods available, our team can assemble a customized solution for you. TransWare is 50.59 and 72.48 qualified at several utilities and has performed work under the utility QA program or under their own NUPIC-approved quality assurance program that meets the requirements of 10CFR50, Appendix B and 10CFR21.

We offer a variety of consulting services at TransWare Enterprises Inc., including marketing, strategy, operations, and more. Our team is made up of experts in each of these areas, and Without an appropriate, long-term view of your fuel loading plan, you can find yourself in a corner, limited by the available fuel and unable to cost-effectively utilize your casks and pad. TransWare can improve the functional and cost performance qualities of your program by making sure that the optimal fuel is loaded in each cask at the right time. Effective fuel loads rely on considerations of available fuel in the pool, cask licensing requirements, and site dose restrictions, among others. By incorporating a holistic approach to our program, we can help you achieve the optimal plan for your plant’s current and future loadings. we work together to provide our clients with comprehensive solutions that meet their unique needs.
Spent Fuel Pool
TransWare has experience performing spent fuel pool dose and flux evaluations to determine the impact of those components on the concrete walls, steel liner and poison plates within the spent fuel pool. We can utilize industry standard tools (MCNP, ORIGEN) as well as our in-house, advanced transport solvers to generate accurate flux and d
TransWare has experience performing spent fuel pool dose and flux evaluations to determine the impact of those components on the concrete walls, steel liner and poison plates within the spent fuel pool. We can utilize industry standard tools (MCNP, ORIGEN) as well as our in-house, advanced transport solvers to generate accurate flux and dose maps of your pool. Additional tools have been developed to support concrete heating analyses that account for environmental and pool conditions to support the determination of the long-term health of the concrete walls and liner of the pool. Our methods have assisted with fuel placement within the pool and the determination of areas of interest for in-situ poison rack measurement campaigns.
Dose Evaluations
- Off-site and occupational dose evaluations based on as-loaded fuel design parameters and pad arrangements.
- Gamma and neutron dose contributions included.
- High-fidelity models support precise surface dose calculations around the entire cask.
- Support for industry-accepted and site-licensed MCNP methods. Additional methods developed in-house provide additional code verification resources.
