Diablo Canyon Power Plant, in operation since 1985, uses two Westinghouse Pressurized Water Reactor units to produce 18,000 gigawatt-hours of electricity. PG&E retained SGH to support the re-evaluation of their Long Term Seismic...
The Institute of Nuclear Energy Research (INER) of Taiwan retained SGH to support the new Seismic Probabilistic Risk Assessments (SPRAs) of three Nuclear Power Plants (NPP), which each use different reactor designs. The Chinshan NPP is a...
Kori Unit 3 is a 900 MW pressurized water reactor that has been in service since 1985. All operating nuclear power plants in Korea are required to perform a Periodic Safety Review (PSR) every ten years against eleven safety elements per the...
The Department of Energy uses the Advanced Test Reactor (ATR) at Idaho National Laboratory to test nuclear fuel systems and materials. SGH engineers performed the experienced-based seismic qualification of Seismic Category I equipment at the ATR...
The 1,097 MW power plant went into commercial operation in 1971 and consists of a single-unit boiling water reactor. The owner/operator of the Mühleberg Nuclear Power Plant (KKM) needed to submit an updated Level 1 probabilistic safety...
Deep Well No. 4 provides make-up water to the Advanced Test Reactor (ATR) in the event of a seismic-induced loss-of-coolant accident. A new diesel generator system was required to supply backup power to Deep Well No. 4. The associated structures...
The Department of Energy uses the Advanced Test Reactor (ATR) at Idaho National Laboratory to test nuclear fuel systems and materials. The light-water moderated and cooled reactor has a four-leaf clover design that allows for a variety of testing...
