In order to aid the establishment of diverse concentrations of power, Kennan believed it was vital to use restraint. For that purpose he suggested a long-term economic aid program. The aid program should treat geographical regions as a whole, and aid recipients should be responsible for the planning.

The U. In order to avoid overexertion the U. Since the Soviet Union projected power toward the outside by relying on communist governments subservient to Moscow and communist parties elsewhere, Kennan suggested to exploit tensions between Moscow and the international communist movement. The Soviet Union would not tolerate independent-minded Czechoslovakia and the Soviet Union could not control communist China. Rather, China may pose a threat to Moscow.

Therefore it made sense to support Titoism in Yugoslavia without assuming responsibility and sometimes even to cooperate with communist regimes.

This crucial technique makes a key contribution to the general safety of the structure. By making use of post-tensioning, owners and designers benefit from a safe and durable containment structure, reduced cost of maintenance, and design simplification while conforming to existing codes.

As a worldwide leader in post-tensioning, VSL offers high-grade systems and services, and can therefore fully optimize the impact of the technology within the overall structure. This ensures the project is completed to the highest level of safety with guaranteed quality, cost, and on-time delivery. This initial package can be extended to include asset preservation and maintenance to guarantee the long-term safety and durability of the containment structure through:.

The inner containment is the most important device that ensures the radiation safety of a nuclear power plant. At the top, it tapers completely to form a sealed dome. The structure of the reactor building of the first unit has now reached a height of The installation of the closing tier was preceded by an equally complex installation of the fifth tier weighing tons.

The two domed parts of the inner containment shell have structural differences from the underlying tiers: they were enlarged into a ring on the site, after which the installation of the finished metal structure was carried out.

The installation of the tiers of the domed part of the inner containment was carried out by one of the most powerful crawler cranes in the world - Liebherr with a lifting capacity of up to tons. The crane was specially delivered to the construction site for this work. Completion of the installation of the dome part of the inner containment shell opens a new front for work in the reactor building.

Work can now start on connecting and starting up the polar crane, installing the reactor vessel, steam generators, and main circulation pipeline, as well as undertaking work on finishing the premises, including cladding structures inside the containment and creating a clean installation zone, which is a prerequisite for starting installation of the reactor vessel. The builders will start concreting the dome of the inner protective shell in March Construction of the inner containment shell for unit 1 took two years — the installation of its first tier was started in December
