'Ib demonstrate compliance with Paragraph III. B. 3, l-certify that the calibration schedule for temperature L
instruments, drop weight, and Charpy V-notch machines connply with the requirements of Paragraph NB-2360 of the ASME Code.
If they are not in compliance, indicate the schedule used and provide a basis for granting an exemption to the exact requirements of NB-2360 of the ASME Code.
s
Response
Calibretion of temperature instruments, and Charpy V-notch impact test machines used in impact testing was required in accordance with the requirements of paragraph NB-2360 of the ASME Code.

especially copper and phosphort 7 (d) Identify the lead factor for each surveillance capsule.
Response
The chemical analyses for the beltline materials are provided in Table 5 3-1.
The surveillance specimens were taken from the RPV belglineareaandthesamplecapsulesarelocatedat30, 1 77 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.
