o PROPOSED AGENDA _FOR_ DISCUSSION OF_ TORUS _ HEADER DESIGN

,e p 1. Generic discussion of ring header torus systems for GE plants.

Identify similarities and diff erences between support systems.

Identify the designer and constructor for etch plant. .

2. Brief description of Quad-Cities ring header showing penetrations, relief valve discharge locations, etc. Deacription of identifi-cation scheme f or supports and penetrations.

3. Description of mathematical model for torus-ring header system, including theoretical bases for dynamic analysis. (Not to include description of computer programs.)

4. Description of test requirements showing how data from test will support model. Include description of instrumentation showing location and type. Compare recent test with previous test performed at Quad-Citics.

5. Describe test and data taken. Discuss parameters measured and show how data provides required information. Describe details regarding orientation of instruments, reasons for location, limitations on capability of test and instruments. Discuss trends indicated by data.

6. Show' how results of tests can be applied to other plants.

7. Discuss basis for f atigue life of torus-ring header system. If usage factor is not used, what means is used to account for fatigue life?

8. Discuss how the static forces, thermal effects, vibration, shock, and earthquake loadings are accounted for in the design. Explain modes of stresses for each loading.
