The ultimate heat sink was restored when the service seawater system pumps in the pump room were repaired in units 1, 2 and 4 starting March 13 restoring the normal ECCS and heat removal systems to operable status and cooling was switched to the Residual Heat Removal System ( RHR ) portion of the ECCS .
