FIELD: nuclear power engineering.
SUBSTANCE: in order to check component 10 such as nuclear fuel pellet of any diameter and length for perpendicularity and to obtain measurement results stable with time, this component is placed on supporting surface and distances separating diametrically opposite generating lines of component from read-our rod T, T' are measured at two different levels and in two measuring planes P, P' normal to one another by means of two pairs of laser micrometers A1, A2; B1, B2. Maximal deviation of component under check from perpendicularity is calculated on them.
EFFECT: enhanced precision of component check for perpendicularity.
