They have offered warm congratulations to the nuclear scientists and technicians for displaying again the might of the country, a nuclear power of Juche, under the plan of the Workers' Party of Korea for building a strategic nuclear force.

Jong Won Sop, a teacher of University of National Economy, told KCNA:

The standardization of nuclear warhead will enable the DPRK to produce as many as it requires a variety of nuclear warheads with a firm hold on the technology for producing and using various fissile materials. It is perhaps a telling blow at the hostile forces.

I am very proud of being a citizen of the DPRK, a full-fledged nuclear power.

The recent test showed the DPRK's capability for mounting nuclear warheads on ballistic rockets, and the enemies can no longer deny the strategic position of our country as a nuclear weapons state.

Choe Kwang Ho, a scientist of the Mechanical Engineering Institute under the State Academy of Sciences, said:

I am very glad to hear the news of successful nuclear test on September 9, the birthday of the DPRK. The test demonstrated the dignity of the country guided by the iron-willed commander as well as the strength of the Korean people.

Only glory is in store for the Korean people dashing toward the final victory in spirit of self-reliance and self-development with the nuclear force.

Following the spirit and stamina of admirable nuclear scientists and technicians, we, researchers of the State Academy of Sciences, will work harder to make signal achievements conducive to the country's prosperity.

Pak Won Sul, a smelter of the Chollima Steel Complex, said that the successful nuclear warhead explosion test was a demonstration of the toughest will of the WPK and the Korean people to get always ready to retaliate against the enemies if they make a provocation.

The more pronounced the hostile forces get in anti-DPRK moves, the stronger the DPRK's nuclear attack capability will grow, and the U.S., an evil empire, will face a bitter nuclear calamity, he said.
