On the basis of the working research WWR-M reactor at PNPI there is being built a highly intensive source of ultracold neutrons (UCN) and very cold neutrons (VCN) for scientific research in fundamental physics and investigation of nanoparticles. The source will use superfluid helium that will allow us to obtain the density of ultracold neutrons of 104 cm-3, which approximately 1000 times exceeds the available density of ultracold neutron at existing UCN sources.
