Short Course

C-10/Seabrook Involvement

C-10 is a “citizen group” that advocates for the safety of Seabrook Station nuclear power plant in order to protect public health and the environment in Massachusetts, New Hampshire, and beyond. It has been very concerned by the Safety of the Seabrook nuclear power plant known to suffer from AAR.

Seabrook Presentation

Seabrook Presentation Placeholder

Sept 4, 2024 presentation to the Advisory Committee on Reactor Safety (ACRS) on behalf of C-10. Presentation, Minutes.

  1. Chapter Case Study: Seabrook Station Unit 1 ASR Problem from my book (PDF)
  2. Consolidated report of key documents I submitted
  3. I have been working (pro-bono) with C-10 to push for greater oversight of the problem by the US Nuclear Regulatory Commission. Read my testimony on why the testing, monitoring and analysis of Seabrook’s concrete is, in my expert opinion, entirely inadequate.
  4. A recent presentation, ASR and Seabrook: 20 Questions and Answers. A summary of this issue and my takeaways, can be found C-10’s Challenge.
  5. Videos of my presentation (and contextual explanation by C-10 board members) at the 2019 annual meeting: Short, Long
