Feeder to IR 50-293/88-27 Inspection Hours:
- 10. 1E Manual 72700 POWER ASCENSION TEST PROGRAM (PATP)
The inspector reviewed the current status of the licensee's Power Ascension Test Program.
In addition, specific issues identified during the Management Meeting on April 8, 1988 were reviewed and are discusseo below.
Power Ascension Procram Startuo Test Review The inspector r evi ewed the licensee's Draft Initial Report regarding their Power Ascension Program Startup Test Review during inspection 50-293/88-14.
The licensee's final report " Independent Review of the Adequacy of Power Ascension Program Testing", dated June 1988 was revi ewed and discussed with licensee representatives during this inspection.
The inspector found the licensee's anal ysi s of the affect of plant modifications on the dynamic response of the plant to be acceptable.
However, the inspector did have a concern regarding the reasons for deficiencies identified in the post modification testing for several plant design changes (PDC) including changes to SBGTS and ADS Logic (PDC's 86-78 and 86-73).
The licensee stated that two PCAQs (Potential Conditions Affecting Quality) have been issued to Engineering anc Modification Management specifically addressing the reasons for the discrepancies in testing.
Resolution of the PCAQs will be reviewed in a future resident inspection.
Rosemount Tr ansmi t t er s The inspector ruviewed BECo Letter #88-117, dated August 4, 1988 regarding Rosemount transmitter " ringing".
This letter was in response to NRC questions regarding " ringing" associated with Rosemount transmitters and instrumenting the level transmitters during the PATP to adequatel y detect " ringing" problems.
The licensee states that the Nuclear Engineering Department performed on evaluation of the Rosemount transmitters installed at Pilgrim and has concluded that Pilgrim's applications are not susceptible to a significant " ringing" problem.
In regards to instrumenting the transmitters during the PATP, the licensee states that monitoring will be performed during the PATP if the EPIC system is operational, otherwise it will be per f ormed during Power Operations following the PATP.
Following discussion with the licensee representatives, for their justification and response, it was 8903030273 890223 m

" Independent Review of Test Results", dated June 15, 1988 which details i
the independent review process to be used during the PATP.
The inspector questioned the Assistant Startup Manager regarding the specifi'c responsibilities of the Systems Engineering Division Manager and the Startup Test Manager during the independent review process.
The Assistant Startup Manager stated that he would revise the Station Instruction to further detail their responsibilities.
He also indicated that he is currently in the process of assigning system engineers to perform the i ndi vi dual review function for each power ascension test.
Findinos No unacceptable condi tions were identified.
