MONTICELLO NUCLEAR GENERATING PIANT i
Docket No. 50-263 License No. DPR-22 Response to NRC Request for Filing of Appendix I Information This letter is to inform you of the measures Northern States Power Company (NSP) intends to pursue to meet the provisions of Section V.B of Appendix 1 to 10 CFR Part 50, for the Monticello Nuclear Generating Plant, he proposed action incorporates the guidance provided in your lette e of February 23, 1976, including Enclosures 1 and 2.
We will demonstrate, by conservative models and data derived from Rt.gulatory Guides 1.AA, 1.C0,1. DD and 1. EE, that the Monticello Plant can be op-erated to meet the Appendix I design objectives.
The following actions will be included:
1.
Plant releases of liquid and gaseous effluents will be calculated cccording to the models and equations set out in Regulator / Guide 1.CC.
2.
Using the release data from Item 1 above, and the dispersion models from Regulatory Guides 1.DD and 1.EE, off-site doses to man will be calculated according to Regulatory Guide 1. AA.
3.
Doses computed from Item 2 above will be analyzed with reference to the design objectives set forth in Section II, Para, A, B and C of Appendix 1.
4.
Appropriate effluent release data from previous reactor operation will be provided and will be evaluated against the so'2rce terms calculated under Item 1 above.
We will gather and develop the additional information outlined in Enclosure 2 to your February 23 letter. This information will facilitate calculation of off-site doses based on ef fluent release data collected during previous re-actor operation.
We scope will include the following categories:
