Kim Jong Un, general secretary of the Workers' Party of Korea and president of the State Affairs of the Democratic People's Republic of Korea, inspected the Nuclear Weapons Institute and the production base of weapons-grade nuclear materials, acquainted himself with the production of nuclear warheads and the current production of nuclear materials and set forth important tasks concerning a long-term plan for increasing the production of weapons-grade nuclear materials.

He was accompanied by Hong Sung Mu, first deputy department director of the Central Committee of the Workers' Party of Korea.

He highly praised the scientists, technicians and officials in the field of nuclear weapons production for carrying out without fail the plan for producing weapons-grade nuclear materials needed for manufacturing nuclear warheads, cherishing the firm and steadfast revolutionary spirit and faith to firmly defend the victorious advance of the revolutionary cause of Juche with the strongest nuclear force.

He went round the control room of the uranium enrichment base to learn about the operation of production lines in all aspects.

He expressed great satisfaction after being briefed on the fact that the base is dynamically producing nuclear materials by studying, developing and introducing all the system elements including centrifugal separators and various kinds of sensors and controllers with its own efforts and technology.

Personally looking round the production site, he said that it is invigorating to see the place, and continued: In order to exponentially multiply the nuclear weapons for self-defence true to the Party's line of building the nuclear force, it is necessary to further increase the number of centrifuges, not content with the successes achieved, and, at the same time, to enhance the individual separation ability of the centrifuge and push forward with the introduction of a new-type centrifuge, which has already reached the completion stage, as planned, so as to consolidate the foundation for producing weapons-grade nuclear materials.

Going round the construction site for expanding the capacity for the current production of nuclear weapons, he learned in detail about the daily plan for the assembly of equipment.

Expressing great satisfaction repeatedly over the great technological capabilities of the nuclear power field of the DPRK, he said that the WPK has set forth a new important strategy for building up the nuclear force, believing in the combatants in the nuclear power field who have turned out as one with an ardent mind to open up a broad avenue for the revolutionary cause of Juche on the strength of nuclear weapons. The red nuclear scientists faithful to the Party should implement the Party's policy of nuclear force building unconditionally and without an inch of deflection with their strong faith and high practical ability, he encouraged.

Noting that anti-DPRK nuclear threat moves of the U.S. imperialists and their vassal forces have become more undisguised and crossed the red-line, he said the security environment facing the DPRK, the peculiarity of the Korean revolution compelling the country to constantly confront the U.S. and contain it and prospective threats require the DPRK to steadily expand and bolster up its military capability for self-defence and the capability for preemptive attack with the nuclear force as the backbone. He stressed again that a more rapid and sure advance should be made in the struggle to always maintain the thoroughgoing counteraction posture of the nuclear force and improve the posture to a high level.

The combatants in the field of nuclear weapons production, assuming the most important responsibility, that is, the historic mission to bolster up the nuclear war deterrent of the country in quality and quantity and in a sustained and accelerated way, should keep exerting themselves in production and thus more creditably fulfil the sacred duty they took on for the Party and the revolution, he instructed.

He stressed the need to set a higher long-term goal in producing nuclear materials necessary for the manufacture of tactical nuclear weapons and concentrate all efforts on making a fresh leap forward, and set forth important tasks and orientation.

Upon receiving his on-site instructions, all the nuclear combatants made a firm determination to make a great leap forward in implementing the Party's nuclear strategy and line by absolutely and firmly guaranteeing the continuous and successful birth of powerful Korean-style nuclear weapons, bearing in mind the deep trust of Kim Jong Un, who put them forward on the outpost of the sacred struggle as he further bolsters the world’s strongest nuclear arsenal which will steadfastly defend the independent development of the state, the happy life and safety of the people and the road ahead for the Juche revolution.
