Item B-35: Confirmation of Appendix I Models for Calculations of Releases of Radioactive Materials in Gaseous and Liquid Effluents from Light Water Cooled Power Reactors

DESCRIPTION

This NUREG-0471[1]task involves evaluating information from semiannual operating reports, inplant measurements program and topical reports, and revisions to models for calculating releases of radioactive materials in effluents from PWRs and BWRs. This task is expected to improve the accuracy and realism of current staff models by using the best available data to develop model revisions.

CONCLUSION

As reported in the main report of NUREG-0933 published in 1983, all work on this Licensing Issue was

completed except the source term measurement program.[2]As a part of the improvements to NUREG-0933, the NRC staff clarified in SECY-11-0101, "Summary of Activities Related to Generic Issues Program," dated July 26, 2011,[3]that the Generic Issues Program will not pursue any further actions toward resolution of licensing and regulatory impact issues. Because licensing and regulatory impact issues are not safety issues by the classification guidance in the legacy Generic Issues Program, these issues do not meet at least one of the Generic Issues Program screening criteria and do not warrant further processing in accordance with Management Directive 6.4, "Generic Issues Program," dated November 17, 2009.[4]Therefore, this issue will not be pursued any further in the Generic Issues Program.
