The inspector described the areas inspected and discussed in detail the inspection findings. No dissenting comments were received from the license The licensee did not identify as proprietary any of the materials provided to or reviewed by the inspector during this inspectio .

IndependentInspectionEffort(72302)

Unit I resumed operation on August 9,1985, following a reactor scram due to a turbine generator rotor low cooling flow transmitter failur The inspector witnessed portions of the startup preparations on August 8 and the startup on August 9. Activities observed included withdrawal of control

..

rods and adjustment of cooling water flow to the turbine generator roto Documentation reviewed included the reactor operator's log, shift technical advisor's log and plant computer output. In addition, the inspector conducted a general inspection of adherence to proper housekeeping and formal behavior in the control room during startup and subscquent operatio All personnel appeared to be attentive to their respective duties and responsibilitie Within the areas examined, no violations or deviations were identifie . StartupTestProgramInspection(72300,72301,72512) The following test procedures were reviewed to ensure t_ hat prepar,ation, review, approval, and revision were accomplished in accordance with applicable administrative requirements. In addition, the Final Safety Analysis Report (FSAR) was reviewed to ensure testing commitments were included in the test procedures. All test procedures reviewed appeared to be adequate. The procedures and the purpose of each are as follows:

(1) 1-833-5U-30-6, Recirculation System, Recirculation Puc Trip section only

-

to obtain Recirculation System performance data durinf the pump trip, flow coastdown and pump restart

-

to record and verify acceptable perfornance of thet Recir-culation System two-pump trip (RPT) circuit '

3 B33-50-30-6, Recirculation System Pump Trip Testing is partially complete. Recirculation Pump 'A' was tripped per section 6 of the test procedure on August 7,1985. The inspector reviewed and evaluated the data obtained against FSAR acceptance criteria and expected test results as outlined on the licensee's test assessment form. Included in the review were the following plant parameters:

(1) Recirculation Pump 'A'

(a) High speed breaker (open/close)

(b) Speed'

(c) Drive flow 2) Recirculation Loop 'A' flow 3) Recirculation Loop 'B' flow 4) ' Core flow (5) feedwater flow (6) APRM Simulated heat flux (7) Reactorvessellevel(narrowrange)

(8) Flow-biased scram (9) Flow-biased rod block Within the areas inspected, no violations or deviations were identifie .
