CH2M Hill

CH2M Hill is one of the joint venture partners operating the former nuclear weapons test site in the US (now called the Nevada National Security Site). The site continues to conduct nuclear weapons related experiments, sending data to both US and UK nuclear weapons laboratories. It was acquired by Jacobs Engineering in December 2017.

Company profile

CH2M Hill, based in the US, provides consulting, design, design-build, operations, and programme management services for the energy, environmental, facilities, resources, transportation and water sectors.[1] On 2 August 2017 it was announced that CH2M Hill will be acquired by Jacobs Engineering Group Inc. in the first quarter of 2018[2]

In the financial year ending 31 December 2016, CH2M Hill generated revenues of US$ 5.2 billion (€5.0 billion), resulting in an operating loss of US$ 240.0 million (€ 227.8 million) and a net income of US$ 15 million (€ 14.2 million).[3]

In December 2017, Jacobs Engineering acquired CH2M Hill.[12]

Nuclear weapons

Together with partners BWX Technologies, Aecom and Northrop Grumman, CH2M Hill is a joint venture partner in National Security Technologies (NSTec). The exact ownership distribution is not known. Since 2006, NSTec has managed the Nevada National Security Site (NNSS), previously known as the Nevada Test Site.[4] The US$ 3.1 billion (€ 2.3 billion) contract includes operation and maintenance of over 500 facilities and laboratories as well as associated infrastructure, vehicles, and IT/communications.[5] The contract expired in September 2016,[6] but has been updated a few times. The last update was in June 2017 for an additional 3 months.[7] The NNSS is the only US nuclear test site where subcritical tests are still taking place, and is a critical facility for the modernisation of the US nuclear arsenal. The most recent subcritical test was the Pollux test in December 2012.[8] In the financial years 2014 to 2016, the National Nuclear Security Administration (NNSA) successfully completed the Lyra-series of three scaled-integral implosion experiments providing information for the US and UK nuclear weapon laboratories; these included Vega, a subcritical experiment in the NNSS complex using a plutonium pit.[9]

The joint venture is responsible for managing the nuclear explosives safety team, as well as support for hazardous chemical spill testing, emergency response training, and more.[10] CH2M Hill claims to be responsible for planning and integration of the entire site, waste management, including operating a low level radioactive disposal facility, environmental restoration of the land contaminated from many years of nuclear testing, and legal counsel.[11]

Top 20 Producers

Looking for information on other nuclear weapon associated companies? Check here.

In some nuclear-armed states – in particular the United States, the United Kingdom and France – private companies are hired by governments to carry out work on maintaining and modernising nuclear arsenals.

This report looks at the top 20 companies that are providing the necessary components to develop, test, maintain and modernise nuclear weapons.The contracts these companies have with nuclear armed countries are for materials and services to keep nuclear weapons in their arsenals. The companies described are substantially involved in the nuclear weapons programmes of the United States, the United Kingdom, France, or India and are themselves based in France, India, the Netherlands, the United Kingdom and the United States. More information on other companies involved in nuclear arsenals, not listed in the top 20, can be found here.

In other nuclear-armed countries –Russia, China, Pakistan and North Korea – the maintenance and modernization of nuclear forces is carried out primarily or exclusively by government agencies.


The nuclear weapon producers identified were selected on the basis of a predetermined set of criteria.
– Information on investments is publicly available.
– The company is directly involved in the development, testing, production, maintenance or trade of nuclear weapons related technology, parts, products or services.
– The company’s involvement is related to warheads, or to delivery systems such as missiles, that are specifically developed for nuclear tasks. This includes technology that is designed for ‘dual use’ (military and civilian) but excludes technology that is not designed for, but can be used in nuclear warfare. It does not include delivery platforms such as bombers and submarines.

State owned or controlled nuclear industries are outside the scope of this research, as are companies not publicly listed. Our research uncovered a number of Universities involved in nuclear weapons programmes, but these are also outside the scope of the report.

The list of nuclear weapon producers investigated was compiled through a wide variety of sources, including financial institution exclusion lists, civil society reports, media reports, etc. Additional details on the contracts and components is on the website.
We welcome information at any time about possible nuclear weapon producing companies to investigate.
