A search for superheavy magnetic monopoles "catalyzing" nucleon decay via the reaction M+N M+e++mesons in an undergound water Cherenkov detector has been carried out. No positive evidence for such a process has been found during 100 d of detector live time. Cross section and velocity-dependent limits on the monopole flux are presented which are as low as Fm<7.2×10-15 cm-2 sr-1 s-1 (90% C.L.). For very low cross sections, velocity-independent limits on the monopole flux and interaction rate are obtained.
