Question: Who helped develop nuclear power, and also worked with Ernest Walton?
Context: Ernest Thomas Sinton Walton (6 October 1903 – 25 June 1995) was an Irish physicist and Nobel laureate for his work with John Cockcroft with "atom-smashing" experiments done at Cambridge University in the early 1930s, and so became the first person in history to artificially split the atom. Since 2004 Nigeria has a Chinese-origin research reactor at Ahmadu Bello University, and has sought the support of the International Atomic Energy Agency to develop plans for up to 4,000 MWe of nuclear capacity by 2027 according to the National Program for the Deployment of Nuclear Power for Generation of Electricity.  Nigeria hoped to begin construction in 2011 and start nuclear power production in 2017-2020.  On 27 July 2007 Nigeria's President Umaru Yar'Adua has urged the country to embrace nuclear power in order to meet its growing energy needs.  Construction has not begun but plans have not been canceled by 2016. The Karachi Institute of Power Engineering, commonly refers to KINPOE, formerly known as Karachi Nuclear Power Plant (KANUPP) Institute of Nuclear Power Engineering, is a post-graduate and engineering university that offers programme to the field of nuclear and power engineering, and the physical sciences.  It also offers Post-diploma Program.  The engineering university located near at the Karachi Nuclear Power Complex (KANUPP-II) near at Paradise Point in Karachi, Sindh Province of Pakistan.  The Institute is known for its research and training in nuclear power engineering and sciences. In the 1960s the Austrian government started a nuclear energy program and parliament unanimously ordered a nuclear power plant built.  In 1972, the German company KWU began construction of the Zwentendorf Nuclear Power Plant boiling water 700 MWe reactor.  In 1976, two years prior to the nuclear power plant opening, the government began a program to educate its citizens on the benefits and safety of nuclear power.  However, this campaign began a public discussion that led to large demonstrations against the Zwentendorf plant in 1977.  On 15 December 1978, the Austrian Parliament voted in favor of a ban (BGBI.  No. 676) on using nuclear fission for Austria’s energy supply until March 1998.  This law also prohibits the storage and transport of nuclear materials in or through Austria.  On 9 July 1997, the Austrian Parliament unanimously passed legislation to remain an anti-nuclear country. The Kaliningrad Nuclear Power Plant (also referred as Baltic Nuclear Power Plant (NPP) or Baltiiskaya NPP, Russian: ) is a nuclear power plant under construction 13 km south-east of Neman, in Kaliningrad Oblast, Russia.  It is seen as a counter-project to the plan to build the Visaginas nuclear power plant in Lithuania and is considered not only as an energy, but also as a geopolitical project.  In June 2013 the construction was temporary stopped for re-designing the project. The Karachi Nuclear Power Complex or KNPC is located in Paradise Point, Karachi, Sindh, Pakistan.  It consists of the Karachi Nuclear Power Plant (KANUPP) and the Pakistan Atomic Energy Commission's Control & Instrumentation Analysis Lab (CIAL KARACHI).  Two new nuclear power plants, KANUPP-2 and KANUPP-3, are also under construction at the site.  When complete, the complex of civilian nuclear power plants will produce over 2000 MW of electricity.  The International Atomic Energy Agency safeguards and inspects the complex.  The plant is under construction by the Pakistan Atomic Energy Commission (PAEC) and is financed by the IAEA, the China Guangdong Nuclear Power Group, the China National Nuclear Corporation, and the China Atomic Energy Authority. Sir John Douglas Cockcroft, (27 May 1897 – 18 September 1967) was a British physicist who shared the Nobel Prize in Physics in 1951 for splitting the atomic nucleus with Ernest Walton, and was instrumental in the development of nuclear power. Vietnam has been considering to develop nuclear power for peaceful purposes based on modern, verified technology since 1995, and firm proposals surfaced in 2006.  However, in November 2016 Vietnam decided to abandon nuclear power plans as they were "not economically viable because of other cheaper sources of power." The nuclear power debate is a long-running controversy about the risks and benefits of using nuclear reactors to generate electricity for civilian purposes.  The debate about nuclear power peaked during the 1970s and 1980s, as more and more reactors were built and came online, and "reached an intensity unprecedented in the history of technology controversies" in some countries.  Thereafter, the nuclear industry created jobs, focused on safety and public concerns mostly waned.  In the last decade, however, with growing public awareness about climate change and the critical role that carbon dioxide and methane emissions play in causing the heating of the earth's atmosphere, there's been a resurgence in the intensity nuclear power debate once again.  Nuclear power advocates and those who are most concerned about climate change point to nuclear power's reliable, emission-free, high-density energy and a generation of young physicists and engineers working to bring a new generation of nuclear technology into existence to replace fossil fuels.  On the other hand, skeptics can point to two frightening nuclear accidents, the Chernobyl disaster in 1986 and subsequently the Fukushima Daiichi nuclear disaster, combined with escalating acts of global terrorism, to argue against continuing use of the technology.  The debate continues today between those who fear the power of nuclear and those who fear what will happen to the earth if we don't use nuclear power.  At the 1963 ground-breaking for what would become the world's largest nuclear power plant, President John F. Kennedy declared that nuclear power was a "step on the long road to peace," and that by using "science and technology to achieve significant breakthroughs" that we could "conserve the resources" to leave the world in better shape.  Yet he also acknowledged that the Atomic Age was a "dreadful age" and "when we broke the atom apart, we changed the history of the world." In the 1980s, during the rule of Nicolae Ceauşescu, Romania had a secret program intended to develop nuclear weapons, violating its ratification of the Treaty on the Non-Proliferation of Nuclear Weapons from 1970.  The program was dismantled after the Romanian Revolution and currently, Romania is considered free of weapons of mass destruction using nuclear power just for civilian purposes.
