In August 2012, Generation entered into an operating services agreement with the Omaha Public Power District (OPPD) to provide
operational and managerial support services for the Fort Calhoun Station and a licensing agreement for use of the Exelon Nuclear Management
Model. The terms for both agreements are 20 years. OPPD will continue to own the plant and remain the NRC licensee.
Nuclear Uprate Program. Generation is engaged in individual projects as part of a planned power uprate program across its nuclear fleet.
When economically viable, the projects take advantage of new production and measurement technologies, new materials and application of
expertise gained from a half-century of nuclear power operations. Once all projects are completed in 2016, Generation will have placed in-service
538 MWs of new nuclear generation.
As of December 31, 2015, under the nuclear uprate program, Generation has placed into service projects representing 536 MWs of new
nuclear generation at a cost of $1,436 million, which has been capitalized to property, plant and equipment on Exelon’s and Generation’s
Consolidated Balance Sheets.
Nuclear Waste Storage and Disposal. There are no facilities for the reprocessing or permanent disposal of SNF currently in operation in the
United States, nor has the NRC licensed any such facilities. Generation currently stores all SNF generated by its nuclear generating facilities in
on-site storage pools or in dry cask storage facilities. Since Generation’s SNF storage pools generally do not have sufficient storage capacity for
the life of the respective plant, Generation has developed dry cask storage facilities to support operations.
As of December 31, 2015, Generation had approximately 75,800 SNF assemblies (18,800 tons) stored on site in SNF pools or dry cask
storage (this includes SNF assemblies at Zion Station, for which Generation retains ownership even though the responsibility for decommissioning
Zion Station has been assumed by another party; see Note 16—Asset Retirement Obligations of the Combined Notes to Consolidated Financial
Statements for additional information regarding Zion Station Decommissioning). All currently operating Generation-owned nuclear sites have on-site
dry cask storage, except for Clinton and Three Mile Island, in which on-site dry cask storage will be in operation at Clinton in 2016 and is projected
to be in operation at Three Mile Island in 2023. On-site dry cask storage in concert with on-site storage pools will be capable of meeting all current
and future SNF storage requirements at Generation’s sites through the end of the license renewal periods and through decommissioning.
For a discussion of matters associated with Generation’s contracts with the DOE for the disposal of SNF, see Note 23—Commitments and
Contingencies of the Combined Notes to Consolidated Financial Statements.
As a by-product of their operations, nuclear generating units produce LLRW. LLRW is accumulated at each generating station and
permanently disposed of at licensed disposal facilities. The Federal Low-Level Radioactive Waste Policy Act of 1980 provides that states may
enter into agreements to provide regional disposal facilities for LLRW and restrict use of those facilities to waste generated within the region.
Illinois and Kentucky have entered into such an agreement, although neither state currently has an operational site and none is anticipated to be
operational until after 2020.
Generation ships its Class A LLRW, which represents 93% of LLRW generated at its stations, to disposal facilities in Utah and South
Carolina. The disposal facility in South Carolina at present is only receiving LLRW from LLRW generators in South Carolina, New Jersey (which
includes Oyster Creek and Salem), and Connecticut.
Generation utilizes on-site storage capacity at all its stations to stage for shipping campaigns and store, as needed, Class B and Class C
LLRW. Generation has a contract through 2032 to ship Class B
