Abstract
Цей винахід стосується головок тепловидільних збірок ядерних реакторів, які компенсують неоднаковість термічного розширювання і зростання тепловидільних збірок та інших елементів реактора при опромінюванні, зокрема - модернізованих здатних до розширювання головок, призначених для використання в реакторах, які до того мали елементи, виготовлені суттєвою мірою з таких самих матеріалів.
