Yuri Alexeyevich Trutnev (Russian:Юрий Алексеевич Трутнев; 2 November 1927 – 6 August 2021)[1] was a Russian physicist and a professor of engineering at theNational Research Nuclear University MEPhI (Moscow Engineering Physics Institute).
His career in physics spent in the formerSoviet program of development of nuclear weapons and was one the designers in theRDS-37 (the Soviet Union's first two-stagethermonuclear device), and theRDS-220 (the largest-ever-yield nuclear device) and many other nuclear charges.
He graduated from the Physics department of theLeningrad State University. In 1951, he was sent to Arzamas-16, also known as KB-11 (English: Design Bureau-11), now theAll-Russian Scientific Research Institute of Experimental Physics (VNIIEF), in the closed city ofSarov,Nizhny Novgorod Oblast. He was one of the main authors of the final report concerning the configuration and feasibility calculations of theRDS-37, which was detonated successfully a few months later in November 1955. For this work, he was awarded theOrder of Lenin, the first of several national awards. He then worked on 'Project 49', withYuri Babayev, which involved technical improvements in the implosion of the two-stage charges, which were tested successfully in 1958 and put into production.Andrei Sakharov selected the design team to develop the RDS-220 which included himself, Trutnev,Viktor Adamsky,Yuri Babayev andYuri Smirnov [ru] (Adamsky andVyacheslav Feodoritov were the project leads). The second and third stages of the RDS-220 were designed principally by Trutnev and Babayev. In 1964, he was appointed head of his department and deputy head of the sector. He was elected a corresponding member of the Russian Academy of Sciences (RAS) the same year. The following year he became head of the sector and in 1966 deputy supervisor. In 1978, he became first deputy supervisor and head of the theoretical department. He became an Academician of the RAS in 1991. From 1993 to 1999, he was first deputy supervisor of VNIIEF.[2][3][4][5][6][7]
Trutnev began development of nuclear devices for industrial civilian purposes such as reservoir creation and gas field intensification, and devices which released very low amounts of ionising radiation.Yevgeny Avrorin described Trutnev producing the first "clean" nuclear charge, "a purely thermonuclear reaction" from a solid compound.[7][8]
Employees at Arzamas-16, including Trutnev, were upset that on a visit byEdward Teller andSiegfried S. Hecker (then director of theLos Alamos National Laboratory) to Russia after the break-up of the USSR, each was photographed in front of a model of the RDS-220 alongside scientists inSnezhinsk. Trutnev insisted that a new photograph be taken of Hecker at VNIIEF in front of a similar model, as it was he and his colleagues at VNIIEF in Sarov who designed the device.[9]
Trutnev was the editor-in-chief of theAtomic Science and Technology journal and deputy editor-in-chief of theInternational Scientific Journal for Alternative Energy and Ecology. He was one of the RAS members who were critical of proposed administrative changes to the RAS by the Russian state in 2013, changes which included the transfer of academic institutions and property (RAS election candidates must now be government-approved and the winner approved by the president).[2][10]
