### Description

Current bounds on mixing angles for light (several keV range) sterile neutrinos are rather weak, though theoretically it is a very interesting region. An interesting experimental technique for analysing such neutrinos is full kinematic reconstruction of the nuclear beta decay. This method, in principle, allows an event by event measurement of the neutrino mass, compared to large statistical noise of the kink search in the usual electron spectrum. I'll discuss advantages and problems of this approach.
