We are pleased to announce the successful completion of our Friction Stir Welding (FSW) development program for joining Metamic-HT®; a nano-particle reinforced Metal Matrix Composite (MMC) that serves both as the neutron absorber and as the structural material of the fuel baskets in Holtec’s latest model Multi-Purpose Canisters (MPC) and transportation casks.  The successful demonstration and qualification of the joining process, the development of which began in earnest after the certification of Metamic-HT by the USNRC in 2009, now gives Orrvilon the option to utilize FSW instead of the previously planned Metal Inert Gas (MIG) welding process.

Holtec has continued its technology leadership in the wet storage of nuclear fuel this past year with new contracts for development of high density racks for the latest generation reactors (APR-1400 and ABWR), for capacity expansion at operating plants, and for site construction services in which the Company has a storied past of heroic achievements going back to the 1980’s. A new milestone in site services was reached last month when the Company successfully de-gassed storage cells at a U.S. Nuclear Plant using remote means, liberating eight (8) used fuel assemblies that had lain entrapped in constricted storage cells for decades. Other pioneering undertakings in 2012 included analyses (and technical solutions, as needed) of Fukushima inspired events such as severe earthquakes, boron dilution, postulated loss of water, and energy impacts of wind born projectiles entering the spent fuel pool. A new passive pool cooling technology, named HI-COOL, was also developed for retrofit at operating plants. (more…)

We are pleased to note, over the past two years, Holtec’s Power Plant Component Division (PPCD) has emerged as a prominent supplier of heat transfer equipment for Nuclear Power Plants. PPCD has designed, fabricated, and supplied numerous heat exchangers and other heat transfer equipment for Nuclear Power Plants based in the U.S. and overseas. Each piece of heat transfer equipment identified below was fabricated at Holtec’s Manufacturing Division (HMD) located in Turtle Creek, Pennsylvania. HMD is a 657,000 sq. feet state-of-the-art manufacturing facility, holding ASME stamps including Section VIII, Section III (Nuclear) and ISO certifications. (more…)
