Unit 2 was in Mode 4, heating up per the Unit 2 startup procedure. Reactor Coolant System (RCS) average temperature was approximately 336 degrees F and pressure was approximately 330 psig with 21 and 22 Si pumps in normal standby per procedure. The inadvertent actuation occurred during performance of a surveillance procedure (SP) to test reactor trip and bypass breakers auxiliary contacts. Plant electricians were installing voltmeter test probes on terminals TB6N-8 and TB6N-9 in Train B Safeguards Rack 2BSG2 in accordance with the procedure to obtain voltage readings during subsequent steps of the SP. After installing atest probe on terminal TB6N-9, the electrician proceeded to install the second test probe on TB6N-8 per the procedure. While installing the test probe, the electrician inadvertently made contact with the adjacent terminal TB6N-

7. This inadvertent contact shorted the two terminals (7and 8)causing Train B SI to actuate by energizing SIB relay. The actuation started Train B safeguards equipment.

Lessons Learned: The root cause was determined to be Interface Desicn - inadequate lavout and accessibility.

Human Performance Safety Snippet Job observations are the best - put your worker practices Before heat up, make sure someone has done to the test. Itwill make us better then the rest. Job the clean-up observations are performed to help reinforce and coach OE57698 April 2004, Palo Verde - Two mechanics workers on observed behaviors. This leads to enhanced received second degree burns to the face as the result of performance. Inthis industry we must strive for a flash fire that occurred as they began pre-heating for continuous improvement. Job observations are a welding. Isopropyl alcohol was used to clean and liquid necessary fact of our jobs. had accumulated in the casing of the equipment. The oncoming crew was not aware of this buildup as they began work.
