SUBJECT:
RESPONSE TO NRC BULLETIN 88-04 On May 5, 1988, the NRC staff issued NRC Bulletin 88-04, "Potential Safety Related Pump Loss."

The bulletin also requested that within 60 days of receipt of the bulletin, licensees provide a written response that (a) summarizes the problems and the systems affected; (b) identifies the short-term and long-term modifications to plant operating procedures or hardware that have been or are being implemented to ensure safe plant operations; (c) identifies an appropriate schedule for long-term resolution of this and/or other significant problems that are identified as a result of this bulletin; and (d) provides justification for continued operation particularly with regard to General Design Criterion 35 of Appendix A to Title 10 of the Code of Federal Regulations (10 CFR Part 50), "Emergency Core Cooling" and 10 CFR 50.46, "Acceptance Criteria for Emergency Core Cooling Systems for Light Water Nuclear Power Reactors."
Additionally, the staff requested that within 30 days of completion of the long-term resolution actions, that licensees provide a written response describing the actions taken.
