Areas of Corporate Excellence


The Team Holtec companies represent an alliance of North America’s most celebrated nuclear service companies. With cutting edge expertise in complementary areas, this alliance can carry out a complex decommissioning program with minimum aggregate dose to personnel and utmost safety. Each member company is an ace in its field.

Nuclear Fuel and Waste Management

Nuclear Fuel & Waste Management

Holtec International provides safe, robust, reliable solutions for managing the backend of the nuclear power cycle. Holtec provides the entire array of equipment and services required to successfully implement used fuel and non-fuel waste projects; providing custom solutions to address client-specific needs.

Heat Transfer Equipment

Heat Transfer Equipment & Services

Holtec’s core heat transfer equipment business focuses on large heat transfer equipment essential to the operation of a power plant. Prominent among such capital equipment are the water cooled condensers, air cooled condensers, feedwater heaters, component cooling water heat exchangers, steam generators, preheaters, superheaters, and auxiliary heat exchangers.

Engineering & Consulting Services

Holtec’s principal mission is to provide design, engineering and consulting services to the world’s electric power industry. Although most of Holtec’s business is derived from the electric power generation industry, the organization is fully equipped to render services to industries as diverse as defense, aviation, chemical, or pharmaceutical.


Holtec International and the Eddy Lea Energy Alliance have partnered to establish an underground consolidated interim storage facility in southeastern New Mexico. The storage facility will store the canisters bearing the fuel underground and will be designed for a 100 year service life with unrestricted capability to retrieve and move the canisters at any time during the facility’s service life.

Neutron Absorber Material

Neutron Absorber Material

Holtec pioneered the development and licensing to structurally qualify the neutron absorber, Metamic-HT, for use as the sole material of the MPC basket for the dry storage and transport systems, serving the dual function of structural integrity and criticality control. Metamic is also exclusively utilized in our high density wet storage racks and our DREAM inserts enabling plants to recover criticality safety margins lost due to neutron absorber degradation or to enhance fuel reactivity following a power uprate.

Custom Fabrication

Reverse Engineered Components

Holtec possess in-house capabilities to design, engineer, analyze, fabricate, construct, and deploy virtually any system, structure or component for our clients no longer wish to procure from the original OEM. Holtec is also versed in enhancing existing SSCs equipment supplied by another vendor that is now an obsolete technology. Holtec has the capability to perform custom fabrication on a 24/7 basis ensuring we meet even the most challenging schedule.

Site Services

Holtec’s goal is to help its clients solve their most challenging problems through innovative thinking, practical engineering, advanced fabrication processes, and experienced site implementation teams. Holtec strives toward this goal with an attitude of continuous improvement, leveraging in-house expertise in technical and licensing services, material development, manufacturing, and site construction services to provide integrated products and services, often on a turnkey basis.



SMR-160 is a passive, intrinsically safe, secure and economical small modular reactor that has the flexibility to be used in remote locations, in areas with limited water supplies or land, and in unique industrial applications where traditional larger reactors are not practical. SMR-160 is walk away safe and can be sited next to population centers without any threat to the local environment or populace.

Davit Crane

Holtec’s Davit Crane for Decommissioning Structurally-Challenged Fuel Pool Enclosure Buildings in Nuclear Plants exploits the load bearing capacity of the fuel pool’s walls and adjacent slab to handle the loaded cask.


Holtite™ Neutron Shield

Holtite is the trademarked name of Holtec’s proprietary neutron shield material that is used for absorbing thermalized neutrons in a neutron-emitting environment. Holtite was first used in the fleet of Holtec’s HI-STAR 100 casks built by Holtec in the late 1990s. Since then Holtite has been been the neutron shield of choice in Holtec’s transportation and transfer casks and even a vertical ventilated cask (HI-STORM MIC) to reduce the neutron dose to infinitesimal levels adjacent to the cask.

Forced Helium Dehydrator

Holtec’s Forced Helium Dehydrator (FHD) provides an alternative to the vacuum dryer. The FHD was certified by the NRC in 2001 and was extensively used to dehydrate Trojan’s fuel assemblies, a number of which had water-laden fuel rods. Since then, over 20 nuclear units utilize the FHD including Chernobyl in Ukraine and Sizewell B in the U.K.


HERMIT (an acronym for Holtec Earthquake Response Mitigator) is a device that was developed and perfected by Holtec to enable cask loading operations to be carried out without physically typing down the cask to protect against earthquakes.

Variable Elevation Cask Pedestal (VECASP)

Holtec’s invention, VECASP, is a device to eliminate the root cause for potential crane contamination, which is the wetting of the crane block and its ancillary parts by the pool water.

Zero Profile Transporter (ZPT)

Holtec developed the so-called Zero Profile Transporter (ZPT) that allows the cask to traverse the truck bay while literally hugging the surface on which the cask is being moved. The ZPT is a “zero height dolly”, i.e., the door openings need only be a smidgen taller than the height of the cask.
