CCC – Nuclear

Spe­cial­ists in a spe­cial­ised field.

Op­er­at­ors and man­u­fac­tur­ers of nuc­lear power plants are very de­mand­ing in terms of safety, re­li­ab­il­ity, qual­ity and func­tion­al­ity when it comes to build­ing, main­tain­ing and re­pair­ing their fa­cil­it­ies. KAEFER meets these strin­gent de­mands with high-per­form­ance in­su­la­tion and fire-pro­tec­tion sys­tems and of­fers a wide vari­ety of ded­ic­ated solu­tions to its cus­tom­ers. De­pend­ing on the loc­a­tion and the spe­cific­a­tions, full metal in­su­la­tion, cas­sette in­su­la­tion or mat­tress in­su­la­tion is used, as well as spe­cially de­veloped and tested fire-pro­tec­tion sys­tems.

KAEFER has es­tab­lished an ex­cel­lent repu­ta­tion amongst nuc­lear power plant op­er­at­ors world­wide. KAEFER en­gin­eers are on site in Brazil, Rus­sia, South Africa, France, Switzer­land and Fin­land. In Olkiluoto, Fin­land, KAEFER en­gin­eers and tech­ni­cians from France, Fin­land and Ger­many are cur­rently work­ing to­gether on the con­struc­tion of the first European pres­sur­ised wa­ter re­actor (EPR). KAEFER is re­spons­ible for in­su­lat­ing the cover of the re­act­or’s pres­sure ves­sel and the primary loop.

The de­mand for nuc­lear en­ergy is con­tinu­ing to grow around the world. And with it, the spe­cial­ist ex­pert­ise to make its use as safe and eco­nomic as pos­sible will grow as well. KAE­FER’s Cor­por­ate Com­pet­ence Cen­ter Nuc­lear has a proven track re­cord in the field and provides the solu­tions you need for the fu­ture.
