Holtec’s Pioneering Technology for Wet Transfer of Used Nuclear Fuel Licensed and Proven as a Safe and Low Dose Operation

Commencement of the movement of used fuel from the storage pool in Unit 3 to the storage pool in Unit 2 at Entergy’s Indian Point Energy Center (IPEC) this week marks the successful culmination of more than three years of work. Holtec International successfully labored at developing a safe set of equipment, processes, and procedures to enable the transfer of used fuel, fully submerged in water, from one fuel pool to another. Under the performance and team-oriented leadership of Joe DeFrancesco, Entergy’s Project Manager, the site will safely place used fuel from Unit 3 into dry storage without the need for extensive modifications to the Unit 3 fuel storage building. This “wet transfer” operation utilizes a Holtec designed Shielded Transfer Canister (STC) designed to hold up to 12 PWR assemblies, and an external shield cask (a HI-TRAC transfer cask). Wet transfer of fuel is admittedly a technically complex evolution because of the two-phase condition (water and steam) that may exist within the cask’s cavity. The benefits of wet transfer, however, are quite compelling. Most prominent is the fact that the fuel remains in its native aqueous environment throughout the transfer process. (more…)

Two‐Year R&D Effort Yields a Safe and Cost Effective Solution for Hauling Casks Heavier Than the Rated Capacity of a Nuclear Plant’s Truck Bay

We are pleased to report that the widely encountered problem of moving modern loaded casks across the nuclear plant’s “truck bay” (typically) designed for much lighter casks of 1970s vintage has been solved. The truck bay in a power plant is the main artery that links the plant to the outside world: It is the area through which all payloads used by the plant (component and machinery) must come and go. Unfortunately, truck bay slabs in a number of U.S. and overseas plants have local areas of structural deficiency that do not permit a modern full size cask, weighing as much as 200 tons, to be hauled across the bay in a conventional manner. This problem has forced some plants in the past to install support columns and girders to buttress the slab at a considerable expense. Others have resorted to temporary palliatives such as “load distribution systems” that must be assembled at each cask loading campaign and disassembled thereafter at considerable effort and cost. A cumbersome structure in the Truck Bay evidently is also an (undesirable) impediment to the movement of tools and equipment into and out of the plant. (more…)

Recover Lost Storage Capacity and Regain Reactivity Control Using Holtec’s Patented DREAM Inserts

We are pleased to report that the U.S. Patent and Trademark Office (USPTO) has issued patent number 8,158,962B1 to Holtec’s engineers for the design and method of installing the DREAM (acronym for “Device For REActivity Mitigation”) insert technology for used fuel storage racks. The DREAM insert serves to replace the neutron attenuation function of the degraded neutron absorber material in the host rack allowing the nuclear plant to recover the lost storage cells and also increase the criticality safety margins in the pool. DREAM inserts consist of precisely formed shapes of Metamic™ with remote handling features. Metamic is a porosityfree metal matrix composite of aluminum and boron carbide widely used for reactivity control in high density fuel storage racks and dry used fuel storage casks. (more…)

License Application for HI-STORM UMAX, the Universal Underground Used Fuel Storage System, Submitted to the USNRC on June 29, 2012

We are pleased to announce the license application for securing the general certification of the HI-STORM UMAX, multi-purpose canister based storage system, was submitted to the USNRC last Friday, June 29, 2012. Engineered to store used fuel canisters in a below-grade configuration, HI-STORM UMAX is anatomically similar to the previously licensed HI-STORM 100U system, the development of which was prompted by the beyond-the-design-basis-threats in the wake of 9/11. HI-STORM UMAX is a larger version of HI-STORM 100U, with enhanced air circulation features and an increased cavity diameter to permit storage of any canister thus far in use at any site in the US.
