S EABROOK C ONDUCT O F O PERATIONS Revision 8 S TATION UFSAR Radiological Analysis Appendix 13A Page 13A-1 APPENDIX 13A RADIOLOGICAL ANALYSIS An analysis has been performed to provide curves for thyroid doses of 5, 25, 150 and 300 rem and whole body ( + ) doses of 1, 5 and 25 rem. Each curve represents a conservative estimate of the elapsed time to reach the specified dose level as a function of distance from the release point under the conditions postulated for the releas e of radioactivity for the design bases loss-of-coolant accident (Subsection 15.6.5.4). These curves do not represent dose as a function of time and distance (x) for any one discrete circumstance, but rather the locus or envelope of highest values of dose that would be expected under a ll wind speed conditions. The doses have been maximized by imposing the concept of an optimal or worst wind speed ( = Tx2)such that the radioactive plume front transit time ( X ) is equal to the actual exposure time ( X T), the sum of the two being the total elapsed time from the onset of release (T). Such an assumption can, however, result in plume velocities that are unrealistically low particularly for short distances.
In order to be consistent with Chapter 15, plume velocities (wind speeds) have been bounded to a lower limit of 1.78 meters sec
-1. This lower limit for wind speed has been determined from the calculated EAB LOCA thyroid dose and 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> /Q value used in the Chapter 15 design bases accident analysis (i.e., a wind speed of 1.78 m/s in conjunction with Pasquill stability Class F assumptions, results in the 2-hour thyroid dose as calculated in Chapter 15, Subsection 15.6.5.4).
Doses have been calculated using the dose conversion factors from Regulatory Guide 1.109, "Calculation of Annual Doses to Man From Rou tine Releases of Reactor Effluents For the Purpose of Evaluating Compliance With 10 CFR Part 50, Appendix I." The following equation has been used to calculate offsite thyroid and whole body ( + ) doses: xQ/T D X T)x(F D Where = Tx2 , min. = 1.78 (meters sec
