Perry Nuclear Power Plant Docket Nos. 50-440; 50-441 Response to Draft SER Materials & Qualifications Engineering Branch
Dear Mr. Schwencer:
This letter and its attachment is submitted to provide revised responses to the concerns identified in the Draft SER for Materials & Qualifications Engineering.
It is our intention to incorporate these responses in a subsequent amendment to our Final Safety Analysis Report.
Very Truly Yours, b44 Dalwyn R. Davidson Vice President System Engineering and Construction DRD: mlb cc:

123 3 To demonstrate the surveillance capsule program complies with Paragraphs II.B' and II.C of Appendix H.
(a)
Provide a sketch showing the azimuthal location of each material surveillance capsule.
(b) Identify each plate specimen in each capsule by heat number and chemical composition, es-pecially copper and phosphorus.
(c)
Identify each weld specimen in each capsule by weld wire type and heat, flux type, lot identification, and chemical composition, especially copper and phosphorus.
(d)
Identify the lead factor for each surveillance capsule.
Response
The most limiting plate and weld material is identified in FSAR Section 5 3.1.6.3 Review of the documentation has confirmed that the surveillance specimens were taken from the most limiting plate material. A similar documentation review for the weld material has confirmed the limiting beltline weld material is included in the RPV surveillance capsule. Certified test reports for the plate and weld material available for review.
The chemical analyses for all of the beltline materials are provided in Table 5 3rl.
The surveillance specimens were taken from the RPV beltline area and the sample capsules are located at 3, 177, and 183 - By symmetry the lead factor for each capsule is expected to be the same with respect to the vessel. These values will be provided in a later amendment.
