In 1985, he moved with Westinghouse to the Waste Isolation Pilot Plant in New Mexico and in 1989 to the Savannah River Site in Aiken, South Carolina. While there, he served in a number of management positions related to business, infrastructure, and information services.
Plung joined Washington Closure when the company assumed management of the River Corridor Closure Project in 2005. He served as manager of Infrastructure and Information Services and then deputy director of Project Services until 2009 when he transferred to Sellafield, England. While there he was a program manager responsible for designing and implementing a management and compliance system. He returned to Washington Closure in October 2011.
He earned a bachelor’s degree in English at City College of New York, as well as a master’s degree and doctorate in English at Idaho State University, Pocatello, Idaho. In addition to his work in the nuclear industry, Dr. Plung has taught as an adjunct faculty member at the University of South Carolina and at Washington State University, Tri-Cities and is author of a college textbook, “Professional Communication: The Corporate Insider’s Approach.”
As controller and CFO, Siron is responsible for all payroll, accounting and financial reporting activities. He began his career as a tax accountant and auditor for Coopers & Lybrand in 1980. He went to work as chief accountant of tax equalization in 1985 for Morrison Knudsen International, later acquired by Washington Group International, then URS.
He served in a series of senior financial management positions with the organization before being transferred to Washington Closure in March 2010. He is a certified public accountant and earned a bachelor’s degree in business at the University of Idaho in Moscow, Idaho.
