During this outage it took only 32 hours.The lessons learned from OPPD’s renovation project have far-reaching consequences for the next generation of nuclear plants. It was the first time this method had been used on a steam generator replacement in the U.S. In addition, the steam generators and pressurizer were covered with asbestos insulation, so OPPD had to remove the asbestos before the components could be removed.All these circumstances—added to the significant number of pipe welds required to reconnect the systems, post-weld heat treatments, nondestructive examinations, and hundreds of support tasks such as designing scaffolding and temporary systems for power and air—made this outage the most challenging ever undertaken.The project staffing plan was a key element in the project’s success. Instead, the team had to use a self-erecting gantry system that traveled on rails from one side of the containment to the other to lift the steam generators (Figure 3). )The team also installed upgraded “rapid fueling” features, including a cable bridge, and performed asbestos abatement on the steam generators and pressurizer. The city includes Fort Atkinson, the first fort built west of the Missouri River. The population was 908 at the 2010 census. Based on data reported to EIA, 420 MW of electricity generating capacity is expected to be added in Nebraska in 2016 and 2017, with wind and natural gas accounting for the new generation.

To cut the 15-foot-diameter hole in the 4-foot-thick reinforced concrete wall, Bechtel had to remove (and subsequently replace) 68 tendons and detension an additional 40 tendons—much higher numbers than the company had encountered on other post-tensioned containment structures. As of August 2016, nuclear power provided 26% of Nebraska’s electricity generation.
The plant is owned and licensed to OPPD, and has been operated by Exelon since 2012. That was the latest proposed restart date for the troubled Fort Calhoun Nuclear Station located about 20 miles North of Omaha. Location of Fort Calhoun, Nebraska. Exelon has announced the planned retirement of its Clinton plant in central Illinois by June 2017, followed by its Quad Cities plant in northwestern Illinois by June 2018 and its Oyster Creek plant in eastern New Jersey in 2019.
(The main condenser and moisture separators had been replaced during a 2005 outage in preparation for this outage. The industry would do well to examine Fort Calhoun’s successful outage plan as a potential template for the future, when new construction schedules will need to be significantly shortened if new projects are ever to get off the drawing board.OPPD’s rigorous planning paid off. In addition to routine maintenance activities planned for every outage, one-third of the fuel assemblies in the reactor core were replaced.The project team encountered many challenges, as would be expected with a project of this magnitude.

Bechtel Power, with more than 30 nuclear renovation projects under its belt, was engaged by OPPD to manage the project, which included more than 5,000 individual scheduled activities. City. Both formal and informal team-building sessions were conducted to fully integrate all the contractors and station personnel. Additionally, Pacific Gas and Electric announced that it will not seek license extensions for its Diablo Canyon nuclear power plant north of Los Angeles, California. Several other nuclear plants have announced plans to retire in the near future.
In addition to accomplishing the most challenging outage in the industry, the work at Fort Calhoun was done safely with no lost-time accidents and came in some $40 million below the $417 million OPPD had budgeted. Entergy Corporation has announced plans to retire its Pilgrim plant in eastern Massachusetts by June 2019. To help unite the various stakeholders into a single, cohesive team, OPPD’s project slogan was “One Team, One Goal.”The scope of work that was completed reads much like a complete plant equipment list.
