I Recuest for Additional Information Materials Engineering Branch - Component Integrity Section Additional information is needed to justify that the value of -50*F used to estimate the nil ductility temperature for tne beltline welds was obtained from test samples that represent the beltline welds in the Zimmer Unit i reactor pressure vessel. This information should include a comparison of the significant weld parameters (e.g., weld wire, flux, tnermal treatment) and mechanical properties from both the sample and beltline welds.

No data has been provided to demonstrate that the impact properties for the ferritic piping valve, and bolting materials in the reactor coolant pressure bound 6ry meet the requirements of Paragraph IV.A.3 of Appendix G.

The actual test data must be supplied so that com-pliance with the paragraph can be demonstrated.

If no data exist 4

for the actual materials at Zimmer Unit 1, data frod the literature for similar materials and/or analyses can be used to demonstrate com-pliance with Paragraph IV.A.3 of Appendix G.

Insufficient data have been supplied to demonstrate that plates C7185-1, C7185-2, C7151-1, and C7158-1, and welds El/3986/3876, E2/3986/3876, DE/04PO46/0217A27A, and DE/05P018/0211A27A have a minimum CVN impact test ucper shelf energy of 75 ft-lb as required by Paragraph IV.B of Appendix G.

The applicant must provide additional data, information from the literature, and/or analyses to. demonstrate tnat an acceptable margin of safety is assured for nor=al operation in the upper-shelf temperature region. The additional data should be from tests of plates having similar steelmaking practices and thermomechanical history. For the welds, the additional data should be from similar welds, i.e., those having the same weld. wire. -flux and thermal treatments as the six iden-tified beltline welds.

2-251.4 Insufficient identification of the surveillance capsule materials and locations have been supplied.

The following cata are required:

Number of specimens in each capsule a.

Azimuthal position of each capsule b.

I.ead factor of each capsule c.

d.

Identification of each specimen in each capsule (1)

Specimen location (plate, weld, heat-affecteo zone) i (2) lieat of base cetal (3)

'4 eld identification numcers and weld wire and ' lux (4) Chemical composition (5) Ther:ramechanical history (5) Type'of ' specimen (CVN impact or tenstie).
