We have carried out interplanetary scintillation (IPS) observations of twelve supernova remnants with the largest in the world decameter radio telescope UTR-2 and new wide-band high-sensitive radiometers at 20, 23 and 25 MHz to determine if any of these remnants contain compact radio sources with angular size less than 10 arcsec. The sample included the young Galactic remnants, the supernova remnants with associated compact sources (compact "cores", pulsars) and the other powerful SNRs. Not surprisingly, we observed the interplanetary scintillations of the compact radio source in the Crab Nebula. This source is considered to be associated with the well-known pulsar PSR B0531 +21. Apart from the Crab Nebula, we have not detected compact radio sources in the supernova remnants with the angular size less than 10 arcsec and the flux density more than 10 Jy. Our observations do not confirm the existence of the low frequency compact source in Cassiopeia A that has remained controversial. As W44, HC24, W50, Tycho and IC443 exhibit the ionospheric scintillations, their angular sizes at decameter wavelengths are less than 50 arcmin.
