- - Page 2 SECTION I Abstract A review is made of safe-end stresses at the safe-end/ thermal sleeve weld location for comparison to s tresses at the corres-ponding location at the Duane Arnold Energy Center of Iowa Electric Power and Light Company, where safe-end cracks oc-curred. The purpose is to evaluate the possibility of crack-ing occurring in the future at Brunswick. Stress figures are extracted from the original design analysis report of the Brunswick plant. These are then compared to Duane Arnold stress figures taken from the original design stress report, but adjusted to be on the same analysis basis as the Brunswick figures. Results show stress levels at Brunswick to be enough lower than at Duane Arnold to substantially reduce the prob-ability of cracking. The crevice-like sleeve / safe-end weld joint is similar, however, which leaves the potential for crack-ing present. Continued in-service inspection surveillance of this section is recommended.

- Page 4 Introduction A review of recirculation inlet pipe stresses at the thermal sleeve to safe end weld joint crevice location is made of the Brunswick Steam Electric Plant (BSEP). Camparisons are made to stresses at the corresponding location of the Duane Arnold Energy Center (DAEC).

The main purpose of the review is to evaluate the stresso, relative to probability of cracking occurring at Brunswick in a similar manner to the cracking which did occur at Duane Arnold.

The design at Brunswick is similar to that at Duane Arnold, with the crevice at the sleeve / safe end joint (see pp. 8 & 9).

The essential similarities and differences of the two designs are tabulated on page 10.

Stresses for Brunswick are from the stress summary sections of the original Chicago Bridge and Iron stress analysis report (Ref.1). These are recalculated as required to avoid non-code assumptions (e.g., addition of stress intensities, rather than stresses, for superimposing stresses from piping loads onto those from pressure and thermal loading; ref.1, pp. S8-21, 31,

& 33) . The stresses for Duane Arnold are recalculated on the same analytical basi.s for proper comparison, taking data from the original DAEC report by CB&I (ref.2).

A plot of primary plus secondary axial stress is made (p.24) using an assumed cycling sequence for Brunswick (since none is given in ref.1). This is for comparison to a similar plot made for Duane Arnold for ref.3, which is reproduced and included in this report (p.23).

Fatigue analyses are made for both Duane Arnold and Brunwick, using the same cyclic requirements for Brunswick as for Duane Arnold, since none are given in reference 1 This also gives a more direct comparison of the two designs from fatigue analysis.

I, 4 k h. h

Page 5 Summary 1 Primary stress intensity for the Brunswick safe er.d c.t the crevice is 60% of that for Duane Arnold.

2. Primary plus secondary stress for Brunswick is 53% of that for Duane Arnold.

3. Peak stress for Brunswick is 305 to 50% of that for Duane Arnold.

4. The fatigue usage factor for Brunswick is less than 2%

of that for Duane Arnold, using the same load cycling for direct comparison.

Page 6 Comments ,

1. It can be seen frc= the summary (pg.5) that Brunswick stresses at the thermal sleeve / safe end joint location are well below those of Duane Arnold. The safe end machining configuration of Duane Arnold made the safe end wall tl.ichness least at this location, which is not the case for the Brunswick design, where propor-tionately greater wall thickness remains at this section.

2. For both designs, stress levels of all Code stress cate-gories (general primary membrane, local primary membrane, primary plus secondary, and peak) are within Code limits.

3. The presence of the crevice formed by the weld joint creates the potential for cracking. The probability cracking will occur at Brunswick is much reduced from Duane Arnold, due to the lower stresses and proportion-ally thicker wall. However, a threshold of stress below which stress corrosion cracking will never occur with the presence of a crack-like crevice has not been established definitely. However it is currently fairly well agreed that for stress corrosion cracking to occur, at least yield stress level is required, along with a corrosive environ-ment and a susceptible material. The safe-end primary-plus-secondary stress level at the crevice of the Brunswick design is approximately equal to yield strength. At Duane Arnold, it was approximately twice yield strength.

4. The assumed residual stress from welding of yield stress magnitude is shown to shake down by load cycling (see plot, pg.24). This is a similar situation to that for Duane Arnold, where it was empnasized that load stresses werr high enough to cause cracking with or without initial residual stress (ref.3,pg. 16).

5. The wider annulus between the thermal sleeve and the nozzle I.D. (.50 radial width vs. .125 for Duane Arnold) should promote better circulation and reduce rate of contamination buildup at the crevice.

1435 185 Conclusion Brunswick stresses are considerably lower than those at Duane Arnold, but the potential for cracking is present because of the weld joint crevice. Crack propagation, should a crack occur, would be expected to be at a much slower rate than at Duane Arnold. Continued in-service inspection surveillance of this section is recommended.

Differences and Similarities of Brunswick and Duane Arnold Designs From study of figures 1 and 2, the significant similarities and differences of the Brunswick safe end design to the de-sign at Duane Arnold are as follows:

Feature Brunswick Duane Arnold Nominal Inlet Pipe Size 12" sched tc 10" sched 80 Nominal Thermal Sleeve Size 12" sched 40S 10" sched 40 Safe End Wall Thickness at Thermal Sleeve Weld 1.125 .575 Crevice Length .50 .50 Annulus Width (betw Thermal Shield and Nozzle I.D.) .50 12 The safe end design at Duane Arnold had the thinnest wall section right at the sleeve / safe end weld joint, whereas, the design at Brunswick is thicker at this location than the pipe wall or the nozzle wall at forming the safe end. This produces lower stresses at the crevice section, as compared on the following pages.
