ABWR PRA CONSEQUENCE ANALYSIS The ADWR PRA consequence analysis reported in subsection 19E.3 (amendment 4) has been updated. The following revised and additional calculations are discussed here The new consequence analysis for the PRA Additional results are also presented.
- 1. ConsequenCM1yfis Result _s 1
Thl calculation was performed as described in Amendments 4 and 8, subsection 19E.3.1 and 19E.3.2. Updated data from the plant performance analysis was used.
Thus, the following tables in amendment 4 or 8 are not changed:
Table 19E.31 Table 19E.3 2. except for the addition of a radialinterval from 30 50 miles.
Table 19E.3 3 Table 19F.3 4 c
. Table 19E.3 5 The CRAC event release parameters (Table 19E.3 6 in amendraent 10) were updated to reflect the new parameters from the updated containment event trees, the added decomposition event trees, and the hiAAP analysis. In addition the relationship between the accident classes used in the MAAP analysis and the grouping used in the CRAC cases are shown it. Table 1 1. : For example, CRAC Case I represents the sbr indicated MAAP cases shown below Case 1. The basic inputs for CRAC were adjusted to adequately represent the several hiAAP cases. Seismic results represented in amendment 10, Table 19E.3 6 are not reflected since analysis of seismic results beyond design basis are now treated by a seismic margins analysis. The new event release parameters are shown in Table 1 1.
The risk and dose results of the consequence analysis are represented in Table 12 (which will replace amendment 8 Table 19E.3 7) and compared to the goals established by the Licensing Review Basis The goals are satisfied by a wide margin.
Table 19E.3 8 and Figure 19E.3 2 will not be needed for the 19E.3 update because :
the rupture disk is now included in the base calculations, The probability of exceeding various dose le els as a function of dose is shown in
' Figure 1 1 which will replace amendment 8 Figure 19E.3 1. The goal of not exceeding 25 Rem at 10+ probability b, achieved.

Additional results were also obtained for NRC review so that a future applicant may l
use these results as pan of an effon tojustify 5;inplified emergency planning. These i
results (Tabic 21) show key parameters for dominant accident sequences.
