Crystal River 3 Nuclear Power Plant

The Crystal River Nuclear Plant, also called the Crystal River 3 Nuclear Power Plant, or simply CR-3, is a closed nuclear power plant located in Crystal River, Florida. As of 2013 the facility is being decommissioned, a process expected to last 60 years. The power plant was completed and licensed to operate in December 1976, and operated safely for 33 years until shutdown in September 2009. It was the third plant built as part of the 4,700-acre (1, 900 ha) Crystal River Energy Complex (CREC) which contains a single nuclear power plant, while sharing the site with four operational fossil fuel power plants. The Crystal River reactor went offline in September 2009 for refueling, OTSG replacement (once through steam generator), and 20% power up-rate outage. In preparing the containment building for making the opening to replace the two OTSG's, tendons in the containment building wall were detensioned. During the concrete removal in creating the opening workers discovered a large gap in the concrete of the containment building wall. The main cause of the gap, which further engineering analysis determined was a large delamination, was attributed to the scope and sequence of the tendon detensioning. The plant had originally been scheduled to restart in April 2011, but the project encountered a number of delays. Repairs were successful, but additional delamination began to occur in adja
