Abstract
The search for CP-violating K_S\to3\pi^0 decay was performed with SND detector at VEPP-2M e^+e^- collider. The total amount of data corresponding to 7 million produced K_S mesons was analyzed. No candidate events were found, giving an upper limit of the decay branching ratio: Br(K_S\to3\pi^0) < 1.4\cdot10^{-5} at 90% confidence level.
