Gus C. Lainas, Assistant Director for Safety Assessment Division of Licensing
SUBJECT:
TELECON - ALMARAZ STEAM GENERATOR EXPERIENCE I received a call today from Jose' Izquierdo (Junta de Energia Nuclear, Spain)(JENS), relative to the status of the Almaraz Unit 1 plant.
As you will recall Almaraz utilizes a D-type steam generator and has experienced mechanical fluid induced tube degradation.
Jose' requested the names and telephone numbers of our ECT and instrumen-tation consultants, which I will provide him.
He also requested infonnation relative to the status of R.G.1.121 and had some comments on the guide.
He will fonnally request this information through International Programs.
Almaraz Unit 1 is currently shutdown and performing ECTs of the steam generator tubes following their last 1500 hour0.0174 days <br />0.417 hours <br />0.00248 weeks <br />5.7075e-4 months <br /> run. The utility has requested to operate the unit at 63% power (50% feedwater flow through the main feedwater nozzle and 13% thro' ugh the auxiliary feedwater nozzle). The JENS is currently reviewing the data obtained from the internal and external instrumentation for the previous runs and the results of the ECTs, when completed, in their approval of future operation of Almaraz, Generally, l
they believe there were indications at 60% power and possibly at 50% power, when the unit was run at these power levels using the main feedwater nozzle.
Jose' wanted to know if we were reviewing the Almaraz data in support of the operation of the McGuire unit.
As you will recall, McGuire is currently operating at 50% power with a request for 60-day operation at 75% power.
I indicated to him that although I had not looked at the recent March 16, 1982 Duke subnittal, I believed that Duke was not using Almaraz instrumentation data in support of their request.

MAR 181992 This data is available to Westinghouse and it seems to me that this data be made available to us and included in our review, since it is the best information that we have relative to the utility of the internal instrumen-i tation.
I will be happy to further discuss this aspect with you. We can also arrange a telecon with Jose' if you like.
