Megatons to Megawatts Program

Last updated

The Megatons to Megawatts Program, also called the United States-Russia Highly Enriched Uranium Purchase Agreement, was an agreement between Russia and the United States. The official name of the program is the "Agreement between the Government of the Russian Federation and the Government of the United States of America Concerning the Disposition of Highly-Enriched Uranium Extracted from Nuclear Weapons", dated February 18, 1993. [1] Under this Agreement, Russia agreed to supply the United States with low-enriched uranium (LEU) obtained from high-enriched uranium (HEU) found to be in excess of Russian defense purposes. The United States agreed to purchase the low-enriched uranium fuel.

Contents

The original proposal for this program was made by Thomas Neff, a physicist at MIT, in an October 24, 1991 Op-Ed in The New York Times . [2] On August 28, 1992, in Moscow, U.S. and Russian negotiators initialed the 20-year agreement and President George H. W. Bush announced the agreement on August 31, 1992. [3] In 1993, the agreement was signed and initiated by President Bill Clinton and the commercial implementing contract was then signed by both parties. The program was successfully completed in December 2013.

Terms of the program

Under this Agreement, the United States and Russia agreed to commercially implement a 20-year program to convert 500 metric tons of HEU (uranium-235 enriched to 90 percent) taken from Soviet-era warheads, into LEU (less than 5 percent uranium-235). The terms of the agreement required that it be implemented on commercial terms without government funds. The agreement named the Department of Energy as the executive agent for the US side. [4] The DOE appointed the newly privatized United States Enrichment Corporation (USEC) as the commercial agent, its executive program contractor. The Russian Federation designated Techsnabexport (TENEX), a commercial subsidiary of its Ministry for Atomic Energy (Minatom), as the agent to implement the program on commercial terms. On January 14, 1994, the commercial contract between USEC and TENEX (HEU-LEU Contract) was signed. The terms also required that the HEU be converted by dilution (downblending) to LEU in Russian nuclear facilities. USEC would then purchase the low-enriched fuel and transport it to its facilities in the US. The first shipment of LEU took place in May 1995.

The value of the process is in two components: the LEU Feed (feed component of natural uranium) and the work involved in the conversion process, measured as separative work units (SWU). Both have separate commercial values. Early disagreements on interpretations of the terms of the governmental and commercial agreements on this issue led to controversy and some delays. Although each shipment contains LEU, the commercial nature of the global uranium market defines the uranium and the enrichment components as separate commercial values and costs. The solution reached was for USEC to continue payments for the SWU component it purchased and also to transfer the equivalent of the LEU feed component to the Russian side. In March 1999, Minatom and the US Department of Energy signed the Agreement Concerning the Transfer of Source Material to the Russian Federation (the Transfer Agreement), and at the same time TENEX signed a Contract with a Group of Western Companies (Cameco, Canada; Cogema, France; Nukem, Germany/US) regarding the purchase of the LEU Feed. As years passed, numerous commercial contract terms were renegotiated and revised to accommodate mutual interests.

Summary of program

The Megatons to Megawatts program was initiated in 1993 and completed on schedule in December 2013. A total of 500 tonnes of Russian warhead grade HEU (equivalent to 20,008 nuclear warheads) were converted in Russia to nearly 15,000 tonnes tons of LEU (low enriched uranium) and sold to the US for use as fuel in American nuclear power plants. The program was the largest and most successful nuclear non-proliferation program to date. The first nuclear power plant to receive low-enriched fuel containing uranium under this program was the Cooper Nuclear Station in 1998. [5] During the 20-year Megatons to Megawatts program, as much as 10 percent of the electricity produced in the United States was generated by fuel fabricated using LEU from Russian HEU. [6]

During this period, on a comparatively modest basis, the US government has also been converting some of its excess nuclear warhead HEU into power plant fuel. Efforts have also been undertaken to demonstrate the commercial feasibility of converting warhead plutonium into fuel to augment nuclear fuel for US power plants.

Nuclear industry sources forecasted high demand trends that would require finding other uranium supply sources after the completion of the Megatons to Megawatts agreement. [6] In 2011, TENEX and USEC signed a long-term contract (Transitional Supply Agreement – TSA) for the provision of enrichment services to the United States that could see annual deliveries after 2015 reaching a level of around half the annual supply volume under the HEU Deal. [7] No plans have been announced for new initiatives similar to the Megatons to Megawatts program.

South Korea has the raw materials and equipment to produce a nuclear weapon but has not opted to make one. In August 2004, South Korea revealed the extent of its highly secretive and sensitive nuclear research programs to the International Atomic Energy Agency (IAEA), including some experiments which were conducted without the obligatory reporting to the IAEA called for by South Korea's safeguards agreement. The failure to report was reported by the IAEA Secretariat to the IAEA Board of Governors; however, the IAEA Board of Governors decided to not make a formal finding of noncompliance. However, South Korea has continued on a stated policy of non-proliferation of nuclear weapons and has adopted a policy to maintain a nuclear-free Korean Peninsula.

The Portsmouth Gaseous Diffusion Plant is a facility located in Scioto Township, Pike County, Ohio, just south of Piketon, Ohio that previously produced enriched uranium, including highly enriched weapons-grade uranium, for the United States Atomic Energy Commission (AEC), US nuclear weapons program, and Navy nuclear propulsion; in later years it produced low enriched uranium for fuel for commercial nuclear power reactors. The site never hosted an operating nuclear reactor. The Portsmouth plant, so named because of its proximity to the city of Portsmouth, Ohio, approximately 22 miles south of the site, was one of three gaseous diffusion plants in the United States, alongside the K-25 plant in Oak Ridge, Tennessee and the Paducah Gaseous Diffusion Plant in Kentucky. The plant was constructed from 1952–1956, with the first enrichment cells going online in 1954. The former plant facilities are currently undergoing decontamination and decommissioning (D&D). Some site facilities are overseen by the United States Enrichment Corporation, a subsidiary of Centrus Energy. The D&D work on the older facilities to prepare the site for future use is expected to continue through 2024 and is being conducted by Fluor-B&W Portsmouth LLC.

Peak uranium is the point in time that the maximum global uranium production rate is reached. After that peak, according to Hubbert peak theory, the rate of production enters a terminal decline. While uranium is used in nuclear weapons, its primary use is for energy generation via nuclear fission of the uranium-235 isotope in a nuclear power reactor. Each kilogram of uranium-235 fissioned releases the energy equivalent of millions of times its mass in chemical reactants, as much energy as 2700 tons of coal, but uranium-235 accounts for only 0.7% of the mass of natural uranium. While Uranium-235 can be "bred" from 234
U, a natural decay product of 238
U present at 55 ppm in all natural uranium samples, Uranium-235 is ultimately a finite non-renewable resource. Due to the currently low price of uranium, the majority of commercial light water reactors operate on a "once through fuel cycle" which leaves virtually all the energy contained in the original 238
U - which makes up over 99% of natural uranium - unused. Nuclear reprocessing is a technology currently used at industrial scale in France, Russia and Japan, which can recover part of that energy by producing MOX fuel or Remix Fuel for use in conventional power generating light water reactors. However, at current uranium prices, this is widely deemed uneconomical if only the "input" side is considered.
