The release amount from the fuel spheres is controlled by the selective corrosion of 14C, which was produced by 14C absorbed at the inner surface of the fuel matrix material (the production rate of 14C can be seen in Table 1).

HTGR utilized large amount of graphite as its moderator and structural materials, resulting in more solid waste than any other types of reactors. [1] The 14C activities are released from the plant to the environment via the leakage at the MPS (Main Power System) and the regeneration of the molecular sieves in the HPS (Helium Purification System) yielding.

The most effective way to solve the problems mentioned above is a reconstruction of the facades with application of highly effective heat-insulating materials for facade insulation.
The data material must be characterized by the availability of raw materials, low energy consumption and low production costs, have the water resistance and frost resistance, mechanical strength, ecological and fire safety.
One of possible solutions of this problem is the reconstruction of facades with the application of thermal insulation material with the thickness of 100 mm.

Fig.1 The model of ring die Fig.2 The model of ANSYS ring mold 1.2 Ring mold material properties In this paper, the materials used in the ring mold is 42CrMo[3].
The material has a high fatigue limit and resistance to several attacks abilities, good low temperature impact toughness after quenched, which is sufficient for the ring mold friction, deformation, and the impact for more times.
This pointed out that if the roller ring mold suffered the squeeze pressure and friction materials, the work surface is wear unevenly, and this will lead to uneven work surface of the ring mold, or disruption of material flow and material, and worse more, the ring mold would stop working.

To have a comparison values, samples from base material were subjected to identical elongation tests.
Results are centralized in table 1 and they permit the following observations: • welded joints strength is superior to base material mechanical strength; • between base material and deposited material is a good compatibility, are avoided stress concentrator because the condition RmDM≤(1.30÷1.35)RmBM is fulfilled (DM - deposited material, BM - base material); • post welding normalization heat treatment determines an increase of fracture strength with 10.8% for welded joint and with 10,98% for base material.
The notch was oriented along thickness of the deposited material.
