r AAB UPOATE OF THE B-SAR-205 SER February 18, 1977 Add the following section:
15.X.5 Rupture of Process Equipment I
Accidents involving process equipment such as the deborating demineralizer and degasifier and the RC bleed holdup tank have been postulated to determine potential off-site doses. These calculations are used in conjunction with the guidelines of f
Regulatory Guides 1.26 and 1.29 to determine the appropriate quality group classification.
l B & W has specified the radiction source terms resulting from l
the postulated failure of tnese components. B & W has indicated that the applicant's SAR will confirm the quality group classi-fication based on these source terms and on actual site meteorology.
An interface requirement nas been established. We concur with this approach in satisfying the guidelines in Regulatory Guides 1.26 and 1.29.
L Make the following changes:
1 1.
Table 15-1, Rod Ejection - Case 2.
Change the 2-hour dose to the thyroid from 81 to 78 rem.
2.
Table 15-3, Case 2 replace the assumptions with the following:
a.
36 percent fuel with clad failures after accident.
b.
Release of total gap activity in failed fuel, c.
Pressure equalization between primary and secondary reached in sixty minutes.
l l
d.
Cooling rate 75' per hour.
