About Holtec International

Holtec International is a global turnkey supplier of equipment and services for the Nuclear, Solar, Geothermal, and Fossil Power Generation sectors of the energy and petrochemical industry. As a fully integrated supplier, Holtec possesses in-house capabilities to design, engineer, analyze, construct, license, and deploy the technologies offered by the company; this includes technologies to manage used nuclear fuel and waste discharged from nuclear reactors and wet and dry (air cooled) heat transfer equipment for commercial power plants. Holtec is also developing a Small Modular Reactor (SMR), which will provide for modular, distributed, carbon-free, base-load energy. Holtec International’s industrial activities are principally focused on six continents: North America, South America, Europe, Asia, Africa and Australia. Britain, Spain, Switzerland, Belgium, China, Ukraine, Canada, Mexico, the United States and Brazil are among the countries where Holtec International has provided significant goods and services. The domestic market in the United States, however, has been the catalyst for Holtec’s technical innovations in its fields of endeavor, which the company has successfully parlayed into business successes in overseas markets. Over 70% of Holtec’s output is consumed by the domestic power industry; the balance is destined for foreign markets. Holtec’s corporate moorings are firmly and deeply anchored in the power industry: Over 150 power generation stations in the U.S., including over 80 commercial nuclear power plants, have been Holtec customers over the past two decades. Holtec International has a long and excellent reputation for honesty and integrity in business dealings. This reputation is a priceless asset which must be safeguarded continually by all Holtec employees. To succeed, Holttec must have the trust and confidence of its customers, subcontractors, suppliers, fellow associates and the public. Maintaining an unwavering commitment to the highest standards of business ethics and conduct is crucial to Holtec’s future.
