MAIN DEVELOPMENT OF THE LABORATORY

  • Physical-technological basis of production of zirconium of nuclear purity for needs of nuclear power. Behavior of impurities during zirconium refining by the method of ELP is investigated. Influence of zirconium purity on its properties is investigated.

     

  • Technology of production of ingots of reactor alloy Zr1Nb produced of domestic raw material for articles for reactor WWER was developed. It was revealed by investigation that obtained ingots meet the requirements for materials of the core of thermal reactors. Specifications (Specs.) for alloys of zirconium with niobium produced by the method of double VAM are developed.

        A batch of  track-tubes of alloy Zr1Nb was fabricated by the method of  solution treatment in industrial conditions in tube institute NITI and experimental-industrial batch of cladding tubes of fuel element with diameter 9,13x0,7mm. Obtained tubes meet the specifications for cladding tubes for fuel elements.

     

  • Development and study of life extension of elements of the core of nuclear reactors are carried out. Technology of magnesium thermal production is developed.

 

  • In accordance to the program of zirconium production in Ukraine the basic data for design of zirconium production are presented.

 

  • Physical basic for fabrication of high-purity hafnium are created. Are performed estimates of variation of impurities concentration in hafnium during ELP for different temperatures of melts and thermal dynamic estimates of the possibility of hafnium deoxidizing at the expense of introduction of third component. Mechanical properties of hafnium in the range 20-1000oC are investigated, Abnormal behavior of mechanical properties at ~700oC is revealed.

 

  • The further development of physical-technologic bases for high purity metals production was proposed. Methods of metals of high purity production were proposed; such methods also may be used for designing of new structural materials.

     

  • Study of the effect of high plastic deformation on properties of Zr and Zr1Nb was performed also as investigation of the influence of regimes of thermal mechanical treatment on structure, crystallographic texture and mechanical properties of Zr1Nb.

     

  • Effect of high power pulsed radiation on characteristics of structure materials is investigated; morphological evolution of specimen surface under plasma treatment of materials used in nuclear power is studied.

 

  • Investigation of life extension for structural materials and welded joints of NPS equipment at the expense of the decrease of hydrogen effect by introduction of getter admixture are carried out.
