Trojan RVP Shleiding Modellnformation; WMG-5783
Dear Sieve,
In responsd to the recent Inquiries from the NRC regarding the RVP QAD models the following Information is enclosed for clarification:
o Revised Figure 5-1 of the SAR - The figure has been revised to include the inner and outer radil of the core baffle region. Notes 4 and 5 were also added to the 4
figul,e for edditional clarification of the assumptions used modeling the core beme and' core former regbns.
Revised Figure 5-2 of the SAR - The figure has been revised to include the core baffa dimensions.
QA@CGGP case input file VSLSOR5.INP. This is the vessel source model for the final shielding configuration with the detector locations'at 2 meters from the conf eyance. This model was used to provide the vessel dose rates in Table 5-7 of l
the SAR. This model input is typical of the geometry inputs used in all the final shielding models.
Plot Jre plot for geometry verification -The Pleture exe program from SCALE 4.3 was usep to generate an X-Z slice of the geometry input for verification purposes. A black and white printout of the color GIF file generated is attached.
If your staff has any questions regarding this Information please do not hesitate to contact me.
Sincerely.
Kevin Tu to Vice Prouldent
