Holtec Manufacturing Division (HMD)

The Holtec Manufacturing Division is located in Turtle Creek, Pennsylvania, a suburb of Pittsburgh located about 10 miles east of downtown and 25 miles from Greater Pittsburgh International airport. The fabrication plant occupies over 175,000 square feet of heavy shop space in the Keystone Commons Industrial Facility (formally Westinghouse East Pittsburgh works, which also housed George Westinghouse’s office, now a registered historic building). This 92-acre site is serviced by truck and rail siding to the factory floor.

All shop areas are serviced by bridge cranes ranging from 10 to 200-ton capacity. Heavy machining is performed on CNC vertical and horizontal milling and boring machines. Two CNC plasma-cutting systems, complete with 14 x 40 foot water tables provide for efficient and accurate part preparation. Metal forming operations are performed with CNC press brakes and bending rolls. HMD employs the latest technology in grit blast and painting in an environmentally controlled autonomous in-shop paint facility. Nondestructive testing capabilities include the entire gamut of methods used in the metal fabrication industry, such as liquid penetrant, magnetic particle, radiographic, helium leak, hydrostatic, ultrasonic, load and functional testing. In addition, the factory is served by a proven array of subcontractors who provide a multitude of services ranging from laboratory testing services to laser metal cutting.

Over 80% of HMD’s manufactured equipment are destined for commercial nuclear plants.

HMD seeks to differentiate itself as a distinguished manufacturer for discerning clients by a total commitment to nuclear quality, by maintaining a first-rate manufacturing infrastructure and by a vigorous program of developing and nurturing high quality craftsmanship. State-of-the-art manufacturing machinery supported by a cutting-edge information management system constitutes the manufacturing infrastructure of the company which has successfully served many blue chip companies around the world by fabricating complex capital equipment fabricated to the exacting codes and standards invoked in their purchase specifications.

While HMD maintains a cadre of skilled industrial engineers in the offices adjacent to the fabrication facility, it also has total and immediate access to the vast technical and management resources at Holtec’s Marlton, New Jersey, headquarters. In all custom-engineered and/or safety- significant projects, the corporate engineering organization based in New Jersey stands ready to support HMD’s manufacturing undertakings.

Another major operational link between the factory and the headquarters is Quality Assurance. To establish complete independence between production and quality, HMD’s quality group reports directly to the corporate QA Manager, based in Marlton, NJ. The Quality personnel are direct employees of Holtec International, while the production personnel are on HMD’s payroll. The organizational independence of QA from production is an important element of Holtec’s corporate organization.

While the great bulk of HMD’s manufacturing output is based on Holtec Nuclear Division’s engineered designs, and is largely of safety-significant pedigree, HMD also manufacturers commercial heat exchange equipment and weldments for the Fossil Power Division. Manufacturing of equipment engineered by external clients (such as GE, Westinghouse, Framatome, and Bechtel) takes place side-by-side with Holtec International-designed equipment.

HMD’s wide range of structural fabrication capabilities for nuclear power plants include safety-related special tools and handling equipment, storage and shipping containers for radioactive waste, heat exchangers, pressure vessels and storage casks, and spent fuel storage components. HMD’s ASME N and NPT Quality Assurance Certifications enable it to design, fabricate, test, and deliver the whole array of capital equipment and structural weldments needed by nuclear plants.

HMD uses a broad range of quality-certified engineering and manufacturing processes that include computer-aided design, precision machining and welding, and performance testing. Operating processes and procedures are continually verified to meet the most stringent requirements of HMD’s customers.

While the company concentrates principally on the manufacturing of complex components made of stainless steel, and exotic metals (like Hastaloy and Titanium), tank and vessels made of carbon steel are also fabricated in the factory in a physically segregated area. As the manufacturing capability data summarized on the website would indicate, HMD’s capability to manufacture complex weldments and structures compares favorably with the best in the world.
