Talk:NUREG-1150

Data requested

Today I again e-mailed and snail-mailed for more information on CRAC-II and NUREG-1150 from John German of Sandia National Laboratories. Simesa 00:17, 22 December 2005 (UTC)

I just received information from the NRC's PDR (Public Document Room) on how to access NUREG-1150 (which I haven't tried yet):

Good Morning,

Thank you for your document request.

NUREG-1150, "Severe Accident Risks, for five US Nuclear Power Plants" is available in PDF in ADAMS, the Agencywide Documents Access and Management System. The one PDF file also contains Appendices A, B, and C, and it is too big to send via e-mail. Here are instructions on how to locate this document in ADAMS:

Begin on the ADAMS page at http://www.nrc.gov/reading-rm/adams.html . This page also includes additional information that you may find helpful. The easiest way to locate this document is by searching Web-based ADAMS, which is linked from this page. This should take you to http://www.nrc.gov/reading-rm/adams/web-based.html .

From this page, click on "Begin ADAMS Search" and then on "Advanced Search". This should take you to the ADAMS Advanced Web Search page. Enter ML040140729 in the Accession Number field (without quotes). Each document in ADAMS has its own Accession Number, beginning with ML which stands for Main Library. Then click Search.

This should bring you to the Web Search - ADAMS Results List page. There should be only this one document listed. It's a 691 page PDF file. To open the PDF you will you need to click on the Image File (the PDF icon), not the title link. However, if you click on the title link you will see the non-official record copy which has text as well.

This process may run slow depending on your Internet connection, as it is a big file.

If you have any questions on searching ADAMS, please contact us again. Our phone reference hours are from 8:30 AM to 4:15 PM, Eastern Time, Monday - Friday (excluding Federal holidays). We can be reached at 301-415-4737, 1-800-397-4209 (toll-free) or pdr@nrc.gov.

Sincerely, Karen Librarian

Note that in the above NONE of the figures is readable in the TEXT file (reached by clicking on the file name) - instead, click on the PDF symbol to the left of the file name. Simesa 03:13, 6 January 2006 (UTC)

Today I received a note from Sandia National Labs that they are checking on the questions I posed and will respond. Simesa 18:07, 4 January 2006 (UTC)

Today I received a phone call from SNL - they have found someone to answer the questions I posed, but that person will not be available for at least two weeks. Simesa 17:59, 6 January 2006 (UTC)

SNL has appointed a responder, but there will be a review process to his answers. Simesa 01:19, 10 January 2006 (UTC)

NRC disclaimer to CRAC-II and NUREG-1150

I just received the following e-mail from the person who signed at the bottom (I will e-mail back to verify that NRC sent this):

Hello;

The Nuclear Regulatory Commission requests you include the following

paragraph, attributed to the NRC, in your Wikipedia entries on CRAC-II

and NUREG-1150:

The U.S. Nuclear Regulatory Commission has devoted considerable

research resources, both in the past and currently, to evaluating accidents and the possible public consequences of severe reactor accidents. The NRC's most recent studies have confirmed that early research into the topic led to extremely conservative consequence analyses that generate invalid results for attempting to quantify the possible effects of very unlikely severe accidents. In particular, these previous studies did not reflect current plant design, operation, accident management strategies or security enhancements. They often used unnecessarily conservative estimates or assumptions concerning possible damage to the reactor core, the possible radioactive contamination that could be released, and possible failures of the reactor vessel and containment buildings. These previous studies also failed to realistically model the effect of emergency preparedness. The NRC staff is currently pursuing a new, state-of-the-art assessment of possible severe accidents and their

consequences.

Please feel free to e-mail me to discuss this.

Scott Burnell ( srb3@nrc.gov ),

Public Affairs Officer,

Nuclear Regulatory Commission

Let's discuss this in this Discussion. Simesa 08:40, 20 January 2006 (UTC)

P.S. - When the report's authors disavow the results, that's of interest to an encyclopedia. Simesa 08:48, 20 January 2006 (UTC)

In terms of style I think adding a short introduction explainning that it is an offical/semioffical whatever disclaimer by the authors of the reports might be better than simply putting it under a heading. But I agree that it is notable and shoudl be included. I wonder if we can find a second source other than email. Dalf | Talk 09:08, 20 January 2006 (UTC)

Good points. I have e-mailed and requested a web source for this. Simesa 09:36, 20 January 2006 (UTC)
