SUBJECT:

PN_0 VERDE STARTUP SPECIM. INSPECTION As a member of the on-shift special inspection team at Palo Verde Power Plant, May 22-28,1985, I observed the day shift including pre-shift-turnover brief-ings. I also observed achievement of initial criticality at 1:45 AM, May 25, 1985 and the first return to criticality at 10:56 AM May 27. In addition to control room oberservations I made two plant tours with NRC and plant personnel to verify equipment performance.

The operating crews which I observed carried out their duties responsibly and professionally. They worked as a team and exchanged observations, questions and cautions. They were knowledgeable about their plant and procedures.

In response to your request, my effort for this project was as follows. I reported 56 prof:hsional staff hours for billing purposes. In addition, I spent about 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> of casual overtime on project activities, exclusive of travel- between Phoenix and the site.

I Spect fic Items Noted During Palo Verde Startup and Low Power Physics Tests 5/22 - 5/28/85

1. The Low Power Physics Test Procedure, 72PY-1RX30, is vastly improved over the Low Power Physics Test Controlling Document, 72PY-lRX03, which it replaced prior to test initiation. Concerns which I expressed in my letter dated May 15, 1985 were remedied by this new procedure.

2. Noted a minor discrepancy between the Test Log and the Control Room Log when reviewing the sequence of actions leading to boration to subcriti-cality which had occurred when I was off shift. The CR log noted a second boron injection between 05:23 and 05:28 on May 27,1985 which was not recorded in the test log. Notations in the test log satisfactorily identi-fled the overboration incident and reported final boron concentration howev e r.

3. Observed some minor confusion concerning the use of "NA" and logging of comments during an operator's first performance of RPS and ESF Channel Surveillances after entry into Mode 2 at 320 F for low power testing.

He consulted with supervision, asked appropriate questions and made reason-able interpretations.

4. Reviewed temporary modifications to nuclear instrumentations Control Channel connections, for hookup of the reactivity computer, during a modification made during testing. Appropriate documentation, tagging and verification procedures were followed.

5. Suggested rewording a step in the recently modified Plant Protective System Functional Testing Procedure. Observed a technician incorrectly interpret an instruction to adjust a negative satpoint value to "20 mV greater than" the value. (He was corrected by the engineer who had modi .

fled the procedure and was overseeing its initial application). Suggested rewording step to "20 mV more positive than."

6. Shift briefing by operations personnel were clear and concise.

7. APS Monitoring and Audit personnel actively reviewed procedures for ade-quacy, change control and documentation of performance aad surveillance data. They provided clarification of administrative detatis to operators and test personnel. Interactions which I observed were cordial and pro-fessional .
