SUBJECT:

Palo Verde Startup Special Inspection '

As a member of the oeshift special. inspection team at Palo Verde Nuclear Generattng Station (PVNGS), May 26-31,19Ei, I observed the day shift operations including pre-shift turnover briefings between on-going and off-going operating crews as well as briefings between Engineertng and Operations. In addition to the control room observations, I also made three plant tours to observe operattons outstde of the control room. i The operating crews that I observed performed their duties in a professional manner. '

They were alert, and had a very positive attitude toward their job. '

The personnel that I observed outside the control room on my plant tours were knowledgeable about their plant and procedures and were profenstonal in the perfonnance of their dutjes.

f i

During the period of observation mentioned above, 40 profenstonal staff hours i were charged to the inspection as well as 10 hours1.157407e-4 days <br />0.00278 hours <br />1.653439e-5 weeks <br />3.805e-6 months <br /> of casual overtime that will not be billed to the inspection.

SPECIFIC ITEMS NOTED DURING PALO VERDE STARTUP AND LOW POWER PHYSICS TESTS MAY 27-31 1.

Low Power Phystes Tests were performed prof tetently with good communication observed between operations and engineering personnel. A ground problem was observed by shift personnel on CEA subgroup 64. Two rods legged the other rods causing a deviation alarm.

ISC was notified and began to take voltage vs the time measurements for each control rod maneuver to determine the nature of problem.

Engini' dures were followed correctly during the test and adequate safety precautions were taken during pump run-up.

4.

D/G A was inoperable due to an excessive amount of microbes found in the fuel tank. Because of this, D/G B had to be started once per shift. After about 11 minutes had elapsed following D/G B start and loading, D/G B tripped due to excessive vibration. This placed Unit 1 into a two hour action statement i as per technical spectftcations. l shooting efforts of plant engineering on D/G B.During this period These I observed personnel carried the out trouble

This procedure step was deviated and the D/G B was Ttarted remotely. Operations explained that this was due to the new diagnostic equipment that had been installed (voltage, frequency, etc.)

and that the procedure was in the process of being changed. I did not

The ongoing surveillance being perfarmed on the RPS was a continuous annoyance and distraction.

The operations crews handled this professionally.

7. In the control room, electronic equipment is available to the operations crew to give an audible alam as a reminder to make hourly log entries, keep track of elapsed time when in action statements etc. This equipment.is not being used to its fullest potential and very few of the operations crews know how to use it. The STA's seem to be the only ones trained on it.
