| -PRESSURE/TEMPERATURE LIMITS (LCR 88-14) A. WCAP-11955 describes the test results of specimens in Capsule Z at Salem 1. The following questions relate to WCAP-11955 which provides the technical bases for the 12/28/88 submittal for Salem, Unit 1: 1. There was no discussion of weld metal in Section 4, Description of Program, in WCAP-11955. | | : 1. There was no discussion of weld metal in Section 4, Description of Program, in WCAP-11955.

| * R4. A chemistry factor of 272°F was obtained for weld metal from Table 1 of Regulatory Guide 1.99, Revision 2 for Cu 0.35 and 1.00 Ni. The base metal chemistry factor of 158.9°F was obtained from surveillance data for plate B2402-1 as follows: (OF) Capsule Flue2'ce n/cm RTNDT ff RTNDT x ff (OF) f f 2 T 0.24 x 1019 100 0.6138 61. 4 0.377 z 1. 33 x 1019 170 1.079 183.4 1.164 244.8 1.541 Chemistry factor = 244.8/1.541

| = 158.9 ff -fluence factor 5. Figure A-2 in WCAP-11955 (corresponding to Figure 3.4-2 in the 12/28/88 submittal). | | A chemistry factor of 272°F was obtained for weld metal from Table 1 of Regulatory Guide 1.99, Revision 2 for Cu 0.35 and 1.00 Ni. |
| R5. Provide detailed/hand calculations to show that when RTNDT of 162°F is used in calculating P/T heatup curve it is more conservative than if RTNDT of 222.5°F is used. Following RTNDT values were calculated for 15EFPY (Page A-8 of WCAP-ll955) . Component EFPY Location ART Plate B2402-1 15 1/4T 204°F Plate B2402-l 15 3/4T 162°F Weld 15 1/4T 222.5°F Weld 15 3/4T 151. 5°F From the above table it is seen that for the 1/4T location, the limiting material is the weld and for the 3/4T location, the limiting material is the plate. Instead of generating two sets of heatup and cooldown curves, a conservative approach is taken by using 0 0 222.5 F RTNDT at the 1/4T and 162 F RTNDT at the 3/4T. This approacfi will envelop both the (B2402-1) and the weld. The Unit 1 Technical Specification heatup and cooldown curves submitted in LCR 88-14 have been revised to indicate both the 1/4T and 3/4T RTNDT values and are submitted herein. 6. Table 4-1 and Table A-1 show inconsistent copper and nickel contents for the base plate B2402-1 and weld metal. Explain. What are the exact percentages of copper and nickel contents used in the calculation of RTNDT of the B2402-1 plate and weld metal.
| | The base metal chemistry factor of 158.9°F was obtained from surveillance data for plate B2402-1 as follows: |

- ATTACHMENT QUESTIONS & RESPONSES - PRESSURE/TEMPERATURE LIMITS (LCR 88-14)
A. WCAP-11955 describes the test results of specimens in Capsule Z at Salem 1. The following questions relate to WCAP-11955 which provides the technical bases for the 12/28/88 submittal for Salem, Unit 1:
- 1. There was no discussion of weld metal in Section 4, Description of Program, in WCAP-11955. However, Table 4-1 discusses weld metal from Capsule Y. Table 4-2 and Table A-1 discusses a certain weld metal but we could not determine whether that weld metal was included in Capsule z. Was there a weld metal included in Capsule Z?
Rl. Salem Unit 1 Capsule z did not contain any weld metal specimens. Therefore, no discussion of weld metal results was included in WCAP-11955.
- 2. Assuming there was no weld metal in Capsule z, then how was RTNDT of the weld metal calculated as shown on Pages A-7 and A-8. It appears that Westinghouse took the weld metal in Capsule Y (WCAP-11554) to be used in the P/T curves in WCAP-11955. Explain.
- 3. Table A-1 showed three weld metals. Which weld metal is the limiting one? That is, which weld metal was used in the calculations on Pages A-7 and A-8?
R2 & R3. The lower shell longitudinal weld seam 2-042C located on a 45° azimuth was considered the limiting weld material as indicated on Page A-7 of WCAP-11955. A chemical content of 0.35 cu and 1.00 Ni was used in developing t~g hea~up/cooldown (H/C) curves. A fluence of 7.68 X 10 n/cm at 15 EFPY for a weld located at a 45° azimuth from table 6-14 of WCAP 11955 was used for H/C curves.
- 4. It appears that the chemistry factor of 212°F as shown on Page A-7 was obtained by using the copper and nickel contents of the weld metal. However, we could not determine how the chemistry factor of 158.9°F for the based plate was obtained. Regulatory Guide 1.99, Rev.
2, provides an alternative method (Section 2.1) to calculate the chemistry factor when two or more credible surveillance data sets become available.
Explain how both chemistry factors (weld and base plate) were obtained.
R4.
A chemistry factor of 272°F was obtained for weld metal from Table 1 of Regulatory Guide 1.99, Revision 2 for Cu 0.35 and 1.00 Ni.
The base metal chemistry factor of 158.9°F was obtained from surveillance data for plate B2402-1 as follows:
Flue2'ce RTNDT (OF) 2 Capsule n/cm ff RTNDT x ff (OF) ff T 0.24 x 1019 100 0.6138 61. 4 0.377 z 1. 33 x 1019 170 1.079 183.4 1.164 244.8 1.541 Chemistry factor = 244.8/1.541 = 158.9 ff - fluence factor
- 5. Figure A-2 in WCAP-11955 (corresponding to Figure 3.4-2 in the 12/28/88 submittal).
Provide detailed/hand calculations to show that when RTNDT of 162°F is used in calculating P/T heatup curve
~ha~ it is more conservative than if RTNDT of 222.5°F is used.
R5. Following RTNDT values were calculated for 15EFPY (Page A-8 of WCAP-ll955) .
Component EFPY Location ART Plate B2402-1 15 1/4T 204°F Plate B2402-l 15 3/4T 162°F Weld 15 1/4T 222.5°F Weld 15 3/4T 151. 5°F From the above table it is seen that for the 1/4T location, the limiting material is the weld and for the 3/4T location, the limiting material is the plate.
Instead of generating two sets of heatup and cooldown curves, a conservative approach is taken by using 0 0 222.5 F RTNDT at the 1/4T and 162 F RTNDT at the 3/4T.
This approacfi will envelop both the pla~e (B2402-1) and the weld. The Unit 1 Technical Specification heatup and cooldown curves submitted in LCR 88-14 have been revised to indicate both the 1/4T and 3/4T RTNDT values and are submitted herein.
- 6. Table 4-1 and Table A-1 show inconsistent copper and nickel contents for the base plate B2402-1 and weld metal. Explain. What are the exact percentages of copper and nickel contents used in the calculation of RTNDT of the B2402-1 plate and weld metal.
R6.
Table 4-1 reports the copper and nickel values obtained for the Salem surveillance materials. Table A-1 identifies the original chemistry reported for the plates and forgings used in the vessel. In this weld metal a chemical composition of 0.35 Cu and 1.00 Ni was used. In the base metal see the response identified in A-4.
B. Other Questions
- 1. 10 CFR 50, Appendix G, Section IV.2 specifies pressure and temperature requirements for the vessel closure flange region. Discuss whether Salem 1 and 2 P/T limits satisfy the requirements.
R1. Salem Unit 1 and 2 P/T limits satisfy the requirements of 10CFR50 Appendix G, Section IV.2 as noted on page A-5 of WCAP-11955 for Unit 1 and page A-6 of WCAP-11554 for Unit 2.
- 2. The Salem Unit 2 P/T curves (Figure 3.4-2 and 3.4-3) in the 12/28/88 submittal show two RTNDT values at 1/4T and 3/4T locations. We could not aeeerrnine which RTNDT was used for the heatup curve and which RTNDT was usea for the cooldown curve. Discuss.
R2. The following RTNDT values were used to develop the heatup and cooldown curves for Unit 2.
Component Location ART Long. Weld 10 1/4T 178.6°F Long. Weld 10 3/4T 116.1°F RTN of 178.6°F at 1/4T location is used to develop coo£down curves and RTNDT of 178.6°F (at 1/4T), 116.1°F (at 3/4T) are used to aevelop heatup curves.
- 3. Table B 3/4.4-1 of the Salem Unit 2 Technical Specification revision in the 12/28/88 submittal: The limiting longitudinal weld in Figure 3.4-2 and 3.4-3 of the Salem Unit 2 Technical Specification revision show the copper content of 0.35% and nickel content 1.00%.
This chemical composition is inconsistent with the weld metals in table B 3/4.4-1.
- R3. Although the chemical composition for Salem Unit 2 weld metal identified in Table B 3/4.4-1 of the Technical Specification is inconsistent with Figures 3.4-2 and 3.4-3, a more conservative chemical content (0.35% Cu and 1.00% Ni) was used for the H/C curves.
