discussion included explanation of the accident initiators and release catagories which dominate public risk results. An additional accident sequence involving steam generator tube rupture due to high temperatures created by core melt was also discussed.
A handwritten list of questions was distributed at the meeting. A typewritten and expanded version of this list is included as Enclosure 2. These questions were formally submitted to the applicant by a letter dated October 8, 1986, from Steven M. l.ong to Robert J. Harrison.
A followup meeting was scheduled for October 16-17, 1986, at Brookhaven National I.aboratory, to pursue further details of containment strength calculations.

Comments on Seabrook Overpressurization Calculations Prepared by SMA
- 1. There is no indication that the c'alculations have been checked or design reviewed.
- 2. The calculations'are difficult to follow and contain many assumptions. A meeting should be arranged between the originator at these cales and the BNL reviewers to better understand the applicant's position.
3 The basis for the assumptions in the calculations should be fully documented. In particular, the uncertainty factors assigned to various pressure capacities must be explained.
- 4. Explain the mechanism for transferring the load from the penetration sleeves to the containment wall, in particular, the equipment hatch, when subjected to high strain conditions. The rebars around the penetrations should be assessed to assure that they can resist these loads in addition to the primary pressure induced loads.
S. The calculations use a rebar ultimate strain value of 4.7%, i.e., more than 21 ft. of linear extension for the hoop bars. This linear extension under the high pressure load will be accommodated by formation of cracks in concrete such that summation of all crack widths will approximately be 21 ft. At such a highly cracked conditon, it is questionable whether the pressure will be carried proportionately by the liner plate and the rebars (similar to the elastic conditons) as was assumed in the calculations.
The liner plate over a large crack area may experience a local extension that could lead to failure. Such possibilities cannot be ignored at this high strain value and should be considered in the analysis.
- 6. It is not clear that the compatibility of strains in the rebars and the liner plate was satisfied in the calculations. For example, the outermost hoop bars will fail before the inside bars and the liner plate reach their respective ultimate strengths. It is not clear that this fact has been reflected in the calculations. In addition, the biaxial stress-strain state of the liner plate should be considered.
7 The combined tension, shear and bending effect at base and spring line levels was not considered in the calculations (Ref. p. 35, assumption 6).
The combined ef fect should be verified.
- 8. Since 31 cadwelds out of a total of 169 test samples failed at a stress lower than the rebar ultimate strength and there was apparently a construction problem concerning staggering of these welds, provide justification for not using a reduced ultimate strengtly for the rebar.
- 9. The containment analysis is based on an axisymmetric geometry and loading.
This is not the case due to the presence of adjoining structures such as the fuel building and main steam and feedwater pipe chase. Such non axisymmetric conditions should be identified and their impact on the failure modes and analysis should be assessed.
em
- 10. Only a sample of pipe penetrations are considered in some detail (X-23, X-26 and X-71). The justification to consider only these should be provided.
- 11. A structural evaluation for electrical penetrations should be provided.
- 12. The basis for the leakage area assigned to the flued head at failure should be provided.
- 13. A more detailed evaluation of the impact of punching shear at the Fuel Transfer Building should be provided. The existing evaluation is very approximate.
- 14. Clarify the extent to which double ended piping failures have been considered in the overall containment'serformance assessment. Provide isometric drawings of all piping attac1ed to containment penetrations.
- 15. In PLG-0465, page 2-10, Figure 2-3, the conditional frequency of exceeding whole body dose vs distance appears to be driven by the S2 source term. If this is the case, please describe all accident sequences (internal and external events) that contribute to the frequency of the S2 source term given in Table 4-2, pg. 4-7. In particular, define how the timing and size of containment leakage was determined for each of these classes of accident sequences. Justify the appropriateness of the binning of each of the accidents into this particular source term.
- 16. Provide justification for the liner yield stress increase from the specified yield stress of 32 ksi to a mean yield stress of 45.4 ksi.
- 17. Indicate the correlation between containment failure sequences and the containment failure modes.
- 18. Provide the basis for concluding that the sight glasses in the hatches will not fall under high containment temperature and pressure conditions.
- 19. Document the effect that the recent update in seismic fragilities will have on the conclusions of the PSA results. .
