Westinghouse Electric Company and CBS Corporation

Naming Rights

Although no longer associated with the current CBS Corporation, Westinghouse Electric Company LLC as of 2011 still uses the trademarks owned by Westinghouse Licensing Corporation,[15] CBS' brand management subsidiary, under license, as is the case with other Westinghouse licensees.

KDKA Radio

Westinghouse Electric Company was the primary sponsor in 2010 for the 90th anniversary celebration of KDKA, a radio station licensed to Pittsburgh, launched by the original Westinghouse on November 2, 1920, and which is now owned by CBS Radio.

New generation of reactors

A revived interest in the nuclear power generation field[when?] led to Westinghouse's development of the AP1000 reactor, the first Generation III+ reactor to receive final design approval from the NRC in 2004.[16] As of 2014, four of these units are under construction in China, though the first was due to come on-line in November 2013.[17] and has been delayed until December 2014. The delay due to the constantly changing, and consequently untested, design prompted Li Yulun, former vice-president of China National Nuclear Corporation, in 2013 to raise concerns over the safety standards of the plant. Citing a lack of operating history, he questioned the manufacturer's assertion that the AP1000 reactor's "primary system canned motor pumps" were "maintenance-free" over 60 years, the assumed life of the reactor, and noted that Westinghouse had yet to receive approval from British authorities on an improved version of AP1000.[18]

As of January 2009, six AP1000 plants had been ordered in the US, and several other customers had chosen the AP1000, if they were to build new nuclear plants, for a combined total of at least 14 new plants, announced by the NuStart Consortium, Duke Power, Progress Energy, Southern Nuclear and SCE&G.[17] In May 2011 after the Fukushima Daiichi nuclear disaster, US government regulators found problems with the design of the shield building of the new reactors. Gregory Jaczko, chairman of the Nuclear Regulatory Commission since 2005 said that computations submitted by Westinghouse about the building’s design appeared to be wrong and “had led to more questions.” He said the company had not used a range of possible temperatures for calculating potential seismic stresses on the shield building in the event of an earthquake, for example. The NRC asked Westinghouse not only to fix its calculations, but also to explain why it submitted flawed information in the first place. Westinghouse countered that the “confirmatory items” that the commission was asking for were not “safety significant.”[19]

In November 2011, the AP1000 Oversight Group published a report highlighting six areas of major concern and un-reviewed safety questions requiring immediate technical review by the NRC. The report concluded that certification of the AP1000 should be delayed until the original and current “unanswered safety questions” raised by the AP1000 Oversight Group are resolved.[20]

In December 2011, the UK’s Office for Nuclear Regulation published a design assessment report on the AP1000 reactor which highlighted 51 'Generic Design Assessment' issues remaining that must be addressed before the assessment would be completed.[21]

In October 2013, US energy secretary Ernest Moniz announced that China was to supply components to the US nuclear power plants under construction as part of a bilateral co-operation agreement between the two countries. Since China’s State Nuclear Power Technology Co (SNPTC) acquired Westinghouses's AP1000 technology in 2006, it has developed a manufacturing supply chain capable of supplying international power projects.[22] Industry analysts have pointed out that there are gaps in the Chinese supply chain.[23]

International business


Westinghouse Electric Company fully owns several subsidiaries in Europe, such as the European Service Center, also called Westinghouse Electric Belgium located in Nivelles, Belgium, where equipment is prepared for projects throughout Europe. After Westinghouse's 1990 takeover of ABB Reaktor in Germany, it transferred radiological storage activities located in Ladenburg, Germany, to consolidate in Nivelles, which had to be extended.[citation needed] Soon afterwards[when?] another expansion was necessary as employees in the Brussels office were transferred to Nivelles. It was estimated that 200 people were working in Nivelles at the end of 2011.[who?][citation needed]

In 2001, Westinghouse took over Logitest in Les Ulis, France, one of 3 companies qualified to inspect nuclear steam generator plants for Electricité de France.[24] After the French nuclear market partially opened in 2004 to suppliers from outside the country to fulfill European Commission directives regarding international competition, Westinghouse started to expand its business in France with a Westinghouse team located in Metz in charge of repair, replacement and automation services. By 2005 Westinghouse had 160 employees in France and two-thirds of Westinghouse's business in France was fuel supply.[25] Westinghouse Electrique France is located in Orsay and Manosque near Marseille (engineering development). As of 2014, about 400 employees are part of Westinghouse in France.

Westinghouse owns a nuclear fuel fabrication plant at Västerås, Sweden which has provided nuclear fuel for nuclear reactors from Eastern Block countries. The 2008 contract with Ukraine has been crucial for the plant.

Nuclear power in Ukraine

Westinghouse also has business locations in Germany, Spain, the UK, Russia, and Bulgaria.


In South Korea, Westinghouse has been involved in the construction of new nuclear plants since 1972, with the first plant Kori Nuclear Power Plant starting up in 1977 and in commercial operation in 1978, followed by eight reactors under construction in the early 1980s. Combustion Engineering (now Westinghouse) entered into a ten-year technology transfer program with the Korean nuclear industry aiming at self-reliance, which was extended in 1997.[26]

In December, 2006, China’s State Nuclear Power Technology Company (SNPTC) selected Westinghouse to provide four new AP1000 nuclear power plants.[14] The first was due to come on line in 2013, has been delayed until the end of 2014.[18]


Westinghouse has been involved in South Africa through support of the Koeberg Nuclear Power Station since the 1990s, both reactors are Westinghouse-licensed. In 2007 Westinghouse acquired IST Nuclear (Pty) Ltd, and won the final bidding process for new nuclear plants in South Africa, for which it signed an MOU in 2013.[27] IST Nuclear provides services and systems for the pebble-bed reactor.

Environmental Record

There have been a number of major Westinghouse-related environmental incidents in the US. Below is a short list of these.

  • Sharon Plant: The Westinghouse Sharon Plant is a 58-acre facility Westinghouse power-plant and production facility in Mercer County, Pennsylvania. The EPA's Recent Second 5-Year Overview (2013) of this toxic Superfund site determined that the Shenango River is heavily polluted due to Westinghouse operations in this area. The report notes that "the PCB concentrations in the fish tissue results for the channel catfish and smallmouth bass samples, an unacceptable risk is present even for [...] consumption rates of one meal per month" [28]
  • Adams County Plant: Westinghouse was fined $5.5 million in 1996 for polluting groundwater in over 100 wells, as well as and other water sources, while operating its Adams County, Pennsylvania plant. Toxic degreasers and other chemicals were released over a 5-year period in the 80s, though the legal battle was not settled until the EPA's involvement. (Pittsburgh Post-Gazette – Nov 12, 1996)
  • Horseheads Site: Westinghouse is responsible for illegal pollution at what is now known as the Kentucky Avenue Wellfield Superfund site in Horseheads, New York. Westinghouse knowingly polluted acres of soil, affecting the safety of a nearby aquifer and wells used by residents. One phase of the clean-up effort describes "Westinghouse Electric Corporation's facility, designated "Disposal Area F" and the "Former Runoff Basin Area," which are contaminated with volatile organic compounds (VOCs), polycyclic aromatic hydrocarbons (PAHs) and arsenic, will be cleaned up using a combination of soil excavation and soil vapor extraction. At Disposal Area F, the area of contamination is about 0.3 acres. At the Former Runoff Basin Area, the contaminated soils cover approximately 0.7 acres. Disposal of the excavated soils will be at appropriate off-site facilities. The removal of the PAHs and arsenic contamination will protect site workers and employees at the Westinghouse facility and the cleanup of the VOCs will help restore the quality of the Newtown Creek Aquifer." [29]
  • Sunnyvale Plant: The extent of the pollution at this Sunnyvale, California site has been found to cover the following: "Groundwater and soil are contaminated with PCBs, fuels, and volatile organic compounds (VOCs). Potential health threats to area residents include accidentally ingesting or coming into direct contact with site contaminants in soil or groundwater." There are municipal drinking water wells within 1/4 mile from this site, and 300,000 people get their drinking water from within three miles of the site.[30]

Sale to Toshiba

In July 2005 BNFL confirmed it planned to sell Westinghouse, then estimated to be worth $1.8bn (£1bn).[citation needed] However, the bid attracted interest from several companies, including Toshiba, General Electric and Mitsubishi Heavy Industries. When the Financial Times reported on January 23, 2006 that Toshiba had won the bid, it valued the company's offer at $5bn (£2.8bn).[31] On February 6, 2006 Toshiba confirmed it was buying Westinghouse Electric Company for $5.4bn and announced it would sell a minority stake to investors. [32] The sale surprised many industry experts who questioned the wisdom of BNFL selling one of the world's largest producers of nuclear reactors shortly before the market for nuclear power was expected to grow substantially; China, the United States and the United Kingdom were all expected to invest heavily in nuclear power.[33] Reasons in favor of a sale were: The commercial risk of the company's business in Asia may have been too high for a company then owned by taxpayers; if Westinghouse won the bid for any new nuclear stations in a UK competition, questions may be raised of favoritism, but if it lost, it might have been seen as a lack of faith in its own technology. Finally, the record of UK governments building nuclear plants had been a commercial disaster.[34]

On October 16, 2006 the acquisition of Westinghouse Electric Company for $5.4 billion was completed, with Toshiba obtaining a 77% share, partners The Shaw Group a 20% share and Ishikawajima-Harima Heavy Industries Co. Ltd. a 3% share.[35] On 13 August 2007 Toshiba sold 10% to Kazatomprom, the national uranium company for the Republic of Kazakhstan, for US$540 million, leaving Toshiba with 67%. Kazatomprom's ownership is entirely passive, with no voting or veto rights or presence on the board of directors.[36]

In September, 2011, Toshiba was reported to be in talks to acquire the Shaw stake[37] and both companies confirmed the story soon thereafter. Shaw CEO James Bernhard said[when?], that Toshiba was paying US$1.6 Bn for the Shaw-owned 20% stake, and that it was the 50% rise in the yen on its yen-denominated debt over five years, which had led it to exercise its sale option. Toshiba said[when?] it was open to, and considering, having other partners invest in the business. The purchase closed in January 2013, and brought Toshiba's share in the company to 87%.[38][39]

In 2015 concerns were expressed that the value of assets and goodwill in Westinghouse were overstated. Following an accounting scandal in which profits were overstated at Toshiba, leading to the CEO resigning, Toshiba stated that the Westinghouse nuclear business was more profitable than at acquisition in 2006.[40][41]

Move to Cranberry Township

After several years of doing business there, Westinghouse decided to move its world headquarters from the Energy Center in Monroeville, Pennsylvania, to Cranberry Woods in Cranberry Township, Butler County, Pennsylvania, as reported in a 2007 memo to its employees[42] that stated the main reason was the rapid expansion of the global nuclear industry. Construction began in July 2007, the move lasted from June 2009 to December 2010. The Repair, Replacement and Automation Services (RRAS) business segment moved to Cranberry Township earlier than other business segments to help alleviate space issues at the headquarters in Monroeville and was completed in spring of 2008. As part of this move, Westinghouse piloted the first commuter shuttle running an all-day loop between Monroeville and Cranberry Township. The shuttle ceased operation after Westinghouse formally closed, and sold their Monroeville facility in 2012.
