MEMORANDUM FOR: Richard H. Vollmer, Director Division of Engineering FROM:
. Joseph Halapatz Materials Engineering Branch
(
SUBJECT:
DIFFERING PROFESSIONAL OPINION This memorandum responds to the memorandum, Vollmer to Halapatz, dated i April 30,1982, subject, " Differing Professional Opinion." The Vollmer to Halapatz memorandum addressed an alternative I proposed to reach resolution of my DPO, given the objection of General Electric to my review of BWR reactor internals fabrication procedures at San. Jose.
The alternative proposed (1) angoing reviews of BWR reactor internals should request that fabrication procedures, including welding and in-process and final heat treatments, be provided, and (2) a review of Monticello ISI records.
The Vollmer to Halapatz memorandum found my alternative plan acceptable and directed that within 30 days I provide you with my estimated schedule for implementing the plan and for reporting my finding and recommendations for resolution of this DPO.
I submit in attachment to this memorandum my planned implementation.of the alternative plan.
In keeping with the direction of your 4/30/82 membr_andum that I may review the fabrication procedures of two SWR OLs whose nTEB-SER inputs have not been provided to OL, I have identified Limerick,,a9 ark II, and River Bend,a Mark 'III, as available (3/31/82 Bevill Report).
I have elected to review Limerick.
My review of the Limerick FSAR indicates that GE has upgraded some reactor internals, replacing Type 304 with less IGSCC susceptible Type 304L.
GE, in the case of Mark IIs of the Shoreham vintage, applied Type 304*dnaterial.
Nevertheless, a review of the Limerick data will provide meaningfgl.. infor-mation. Because GE, in the case of River Bend internals, upgraded ~exten-sively to Type 304L, a review of River Bend data is likely to be less mean-ingful.

Richard H. Vollmer Accordingly, I submit in attachment to this memorandum in standard format, a request for information on Limerick internals, as addressed within the context of SRP Section 4.5.2, " Reactor Internals Materials."
I estimate that my review of the data will be completed within 30 calendar days after receipt.
With respect to my review of Monticello ISI records, I submit in attachment to this memorandum a formal request that I be granted onsite access to these records for a time not to exceed two workdays, to be scheduled within the most mutually compatible time frame following my revicw of the Limerick data.
I estimate that within 30 calendar days after my review of Monticello ISI records I will provide you a report of ry findings and recommendations for resolution of my DPO.

This memorandum responds to the memorandum, Vollmer to Halapatz, dated I April 30,1982, subject, " Differing Professional Opinion." The Vollmer*
to Halapatz memorandum addressed an alternative I proposed to reach resolution of my DPO, given the objection of General Electric to my review of BWR reactor internals fabrication procedures at San Jose.
The alternative proposed (1) ongoing reviews of BWR reactor internals should request that fabrication procedures, including welding and in-process and final heat treatments, be provided, and (2) a review of Monticello ISI records.
The Vollmer to Halapatz memorandum found my alternative plan acceptable and directed that within 30 days I provide you with my estimated schedule for implementing the plan and for reporting my finding and recommendations for' resolution of this DPO.
I submit in attachment to this memorandum my planned implementation of the alternative plan.
In keeping with the direction of your 4/30/82 memorandum that I may review the fabrication procedures of two BWR Ols whose MIEEWSER inputs have not been provided to' DL, I have identified Limerick, a; Mirk II, and River Bend a Mark III, as available (3/31/82 Bevill Report).11 have elected to review Limerick.
