April 20, 2016, Soddy Daisy, Tn.,TVA Sequoyah Nuclear Facility - NRC 2015 Annual Assessment Questions about the January 2015 Fine Levied Against TVA - Q&A about Event Reports - 5 Scrams on Unit 1 Sequoyah. NRC to increase oversight on Sequoyah Unit 1 due to number of unplanned shutdowns, scrams:http://www.nrc.gov/docs/ML1531/ML1531... Also in 2015, TVA was fined for earlier Sequoyah regulatory findings related to no Fire Watches and Falsification of Records by contractor - http://www.timesfreepress.com/news/local/story/2015/mar/12/tvfined-fire-safety-violations-nuclear-plantc/292823/

The SOARCA Process

(NRC-The SOARCA Process - Fair Use for non-profit news reporting.)

Overall, the State-of-the-Art Reactor Consequence Analyses (SOARCA) process includes five general steps, as illustrated in the flowchart to the right. See the following pages for discussions of the methods and rationale that the project team uses in each step to determine the realistic consequences of the select severe accident scenarios:

Bias in Health Effects Modeling?

April 20, 2016 Soddy Daisy, Tn., Sequoyah Nuclear Facility; Nuclear Regulatory Commission (NRC) State-of-the-Art Reactor Consequence Analyses (SOARCA), Public Information Session. This video highlights offsite health consequences of a severe accident, modeling; focus here is on skewered health risk factors - fact vs fallacy in NRC's modeling program. NRC - SOARCA site modeling of health effects indicates bias in modeling of health effects in support of the nuclear industry. The bias is evidenced in this video.

NRC Reference: http://www.nrc.gov/about-nrc/regulatory/research/soar/soarca-health-effects.html There is no reference in the NRC link to the BIER VII Report which strongly supports the linear no-threshold (LNT) model. However, the NRC site states - "The risk of a latent cancer fatality (LCF) from chronic exposure to low doses of radiation is very uncertain." The NRC site goes on to state it utilized the BIER V Report, which has been updated by the BIER VII Report which is ignored by the NRC. Inquiries addressed to NRC personnel and Sandia National Laboratory present indicated they apparently did not include specific groups of people in their health consequences modeling, e.g. infants, pregnant women young women of child bearing age and children who are most susceptible to ionizing radiation exposure.

My apologies for the sound quality. The training room has a speaker system, however it is never used for public meetings such as this. I have complained to the NRC about the poor sound quality and I have ask for them to utilize the sound system. Unfortunately they are not responsive to having good sound so that participants may actually hear the presentation.
