Significant changes in fl~w f~om the sump:would be observed by level observations, annunciator alarms, PT 36, and reduction of volume available in the liquid waste syste Due to recent problems with the installed containment sump pumps, the licensee removed the pumps and is utilizing portabla submersible pumps in the sumps; the portable pumps require less maintenance and therefore reduce contain-
