OPENING REMARKS J.
B. Martin, Regional Administrator LICENSEE'S PRESENTATION ON RECENT EVENTS J.
D. Shiffer, Vice President Nuclear Power Generation Exam les of Poor Disci line, Professionalism and Attitude Containment ventilation isolation (May 26, 1987) due to source check on wrong radidation monitor while distracted by telephone.
ISC techs hookup to wrong unit for SSPS work on May 25, 1987.
IEC tech's failure to stop for instructions on inadequate loop test resulted in diesel start May 14, 1987.
Operators failure to stop on divergent RCS level indications results in RHR vortexing May 12, -1987.
Failure to check clearance by several licensed operators resulted in a spill to charging pump room May 8, 1987.
Use of inappropriate wording on annuniciator by operators April 19, 1987.
Flame heated RHR pipe without management involvement April 1987.
Operator commenced turbine rollup contrary to policy of no significant activities during shift brief Reactor trip resulted March 3, 1987.
Exam les of Miscommunications due to Informalit A disconnect between procedure and training for mid-loop operations was observed by inspectors May 29, 1987.
Inoperable underfrequency relay was incorrectly maintained as operable April 19, 1987.
Failure to communicate intent of flame heating RHR line as a test of the process April 1987.
For loss of RHR on April 10, 1987, operations was not informed of LLRT
- start, there was conflicting directions-to operator for RVLIS and SG manway verification, and the turnover of prior shift vortexing was incomplete.
Unit 2 reactor trip on failure to communicate implications of rollup of tur bine on auxiliary feedwater system March 5, 1987.
gC and mechanical maintenance failed to communicate on problem with auxiliary feedwater pump slinger ring February 1987.
Failure to Follow Procedures ISC technicians failed to follow procedural precaution on inoperable underfrequency relay April 19, 1987.
Operators failed to follow procedure on RCS level resulted in a long-term loss of RHR April 10, 1987.

Fuse failure that caused-Node 3 reactor trip Nay 11, 1987, not adequately followed-up.
Inadequate corrective action for shorting radiation monitor that resulted in CVI Nay 10, 1987.
Failure related to ualit Or anizations gC involvement in flame heating RHR pump inadequate April 1987.
gC on RVLIS inadequate for April 10, 1987 loss of RHR event.
