LEAKAGE DISCOVERED ON "B" HOT REACTOR COOLANT SYSTEM (RCS) HOT LEG INSTRUMENT NOZZLE CONNECTION.
A maintenance supervisor reported that there was leakage on a pipe to nozzle connection on line I-3/4-RC-126. After further investigation this line has been determined to be the "B" RCS Hot Leg instrument nozzle connection for differential pressure (D/P) transmitter PDT-1121D. PDT-1121D measures the D/P across "B" Steam Generator. This D/P is used as input to the "D" channel Reactor Protection System low flow trip. A chemistry sample confirms boric acid and active iodine. Leakage was reported to be indeterminate i.e., no drops per hour could be quantified. This problem will be corrected before going above 190 degrees F. An LER will be issued.
The NRC Resident Inspector was notified of this event by the licensee.
