NEPA/SAMDA Submittal for the ABWR l
Reference:
Letter,J.F. Quirk to R.W. Borchardt, same title, August 26,1993, min No.137-93 i
The attached Technical Support Document (TSD) for the ABWR supersedes the TSD transmitted August 26,1993 (reference). On October 6,1994, GE met with NRC staff senior management to discuss the staffs comments on GE's proposed
. introduction to the Design Control Document (DCD). One of the items agreed to was not to incorporate ABWR SSAR Appendix 19P with its probabilistic values into the DCD, but incorporate this information into the TSD. An updated version of Appendix 19P (see attached markup) was incorporated as Attachment A to the TSD. Several editorial changes accompanied the updated
- technical information in forming Attachment A.
l The conclusions remain unchanged and GE believes that this TSD provides a sufficient basis for the NRC to issue an amendment to 10CFR51 which concludes:
- 1) that the probability of severe accidents in the ABWR is remote and speculative,
- 2) that the risks of severe accidents and the radiological impacts of normal operation of the ABWR do not constitute a significant impact to the quality of the human environment, and
- 3) that there are no reascmable alternatives for reducing these risks or impacts.

'19P.4.2.4 Safety-Related Condensate StorageTank
' The current ABWR design consists of a standard non-seismically qualified Condensate _-
Storage Tank (CST). This modification would upgrade the structure of the CST such l
that it would be avalable to provide makeup to the reactor following a seismic event.
- l This modificadon only benefits the risks of core damage following seismic events.
However, because the suppression pool provides an alternate suction source and the HCLPF for the suppression pool is relauvely high (Appendix 191), the dominant failure '.
l modes are not limited bywater availability. Therefore the benefit of this modification is l
considered small. A benefit of OE person-Sievert averted was arbitranly chosen for.-
l an upgnded CST.

,,4 A/p 7 l
i. o s.-4 742 q
e 19P.4.3 Containment Capability i
l-The ABWR containment is designed for about 0.411 MPa internal pressure and includes a containment rupture disk which would relieve excessive pressure ifit develops during a severe accident. By providing the release point from the wetwell i
airspace, mitign. tion of releases are achieved through scrubbing of the fission products.
l in the suppression pool.
19P.4.3.1 Larger Volume Containment This modification would provide a larger volume containment as a means to mitigate the effects of severe accidents. By increasing the size the containment could be able to absorb additional noncondensible gas generation and delay activation of the containment rupture disk or early containment failure.
i This item would mitigate the consequence of an accident by delaying the time before l
the severe accident source term is released and allowing more time for radioactive decay i
and recovery of systems. However, if recovery does not occur, eventual release is not l
prevented and if operation of the containment ove: pressure rupture' disk does not i
occur, ultimately the containment will fait due to the long term pressuruation caused by core concrete intemcuon an s
generanon.
0u+
If sequences involving drywell head failure were eliminated (Cases 3,6,7,8 and 9), the l
l offsite risks would be reduced by about 82% and about 15E-04 person-Sievert would be j
averted.
19P.4/5.2 Increased Containment Pressure Capacity The design pressure of the ABWR containmentis 0.411 MPa (45 psig).The containment rupture disk pressure and ultimate capability are significantly higher. By increasing the ultimate pressure capability of the containment (including seals), the effects of a severe accident could be reduced or eliminated by delaying the time of I" valuation of Potential Modificatrons to the ABWn Design - Amendment 34 19P 9
