Many experts were killed on the spot Russian President vladimir putin cut short his trip to Crimea after an explosion at Russia's Arkhangelsk launch site killed five nuclear experts and other technicians, Russian media reported. The report said radiation levels in the area had suddenly risen after the explosion, raising suspicions of a nuclear leak. Russian officials said the explosion was a liquid-fueled rocket engine, and that the impact of the blast on the container containing nuclear waste caused abnormal radiation readings. The issue has now been resolved and radiation levels have returned to normal levels.

However, us media reported that the problem was far more simple than Russia claimed. Russia's official announcement of a liquid-fuel rocket engine explosion was caused by an explosion while operating on the engine's propulsion system's "isotopic power source", which is actually a nuclear battery. It is likely to be the Haiyan nuclear-powered cruise missile that Russia has announced it is developing.

According to reports, the Haiyan nuclear-powered cruise missile is a new type of missile demonstrated by Russia in 2018. The missile adopts a technology that has never been used before, which applies nuclear technology to the missile and USES it as power propulsion. According to Russian officials, the "Haiyan" nuclear-powered cruise missile USES a nuclear-powered engine, which enables the missile to have almost unlimited range and very high speed, so it is very difficult to intercept. Some American media rated the missile as "invincible".

The missile was first developed in 2017 and first test-fired in 2017 to test the performance of the small nuclear reactor it USES. Because the missile USES nuclear reactors that lack the conditions to shield it from radiation at high speeds, its flight will leave behind a radiation belt that will contaminate non-target areas and even affect the safety of the entire world. And if the missile malfunctions during launch, it is likely to cause a nuclear leak, and the explosion is likely to be caused by the failure of the Haiyan cruise missile launch.

Haiyan cruise missiles, experts said, while performance is strong, but it's not a mature weapons, unlike traditional nuclear weapons, nuclear weapons in the process of flight will not cause contamination, will only cause certain nuclear pollution to target area, however, Haiyan cruise missiles from after launch to hit the target flight path will all contaminated, including the launch of a missile. If fired from central Russia, the missile would contaminate parts of the country and be a weapon capable of inflicting up to 1,000 casualties. And if the weapon is used frequently, the whole world will be covered by nuclear pollution, and the safety of the whole world will be threatened by the Russian weapon. And even if Russia says it was not the missile itself that exploded but a nuclear missile, it shows the risks posed by the missile's immature technology. Whether Russia can solve this problem will directly affect the radiation level of the whole earth in the future.(From CNNPN)
