The kinetic equation of point reactor in the case of small step reactivity input (0 <ρ0 <β) with temperature feedback is studied. The analytic expressions of power, reactivity and time of the reactor at any initial power are derived. The effects of the initial power and the input small step reactivity on the variation of power and reactivity are discussed, and some new results are obtained
