ENCLOSURE QUESTIONS - 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?

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?

4.

It appears that the chemistry factor of 272°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 base 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.

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 RTNnT of 162°F is used in calculating P/T heatup curve that it is more tonservative than if RTNDT of 222.5°F is used.

6.

Table 4-1 and Table A-1 show inconsistent copper and nickel contents for the base plate 82402-1 and weld metal. Explain.

What are the exact percentages of copper and nickel contents used in the calculation of RTNDT of the 82402-1 plate and weld metal.

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.

~ Z.

The Salem Unit Z PIT curves (Figure 3.4-Z and 3.4-3) in the lZ/ZB/BB submittal show twO RT~DT values at iT and 3/4T locations.

We could not determine which RTNnT was used for the heatup curve and which RTNDT was used for the cooldown curve.

Discuss.

3.

Table B 3/4.4-1 of the Salem Unit Z Technical Specification revision in the 12/ZB/BB submittal: ~e limiting longitudinal ~ld in Figure 3.4-Z and 3.4-3 of the Salem 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.
