Licensing Support Network

for Documents Relating to 

the Yucca Mountain Licensing 

Proceeding Conducted by 

the U.S. Nuclear 

Regulatory Commission

The LSN is Operated by:

Atomic Safety & Licensing Board Panel

U.S. Nuclear Regulatory Commission
What is the

Licensing Support Network (LSN)?

• The Nuclear Regulatory Commission (NRC) 

review process for the Department of Energy 

(DOE) license application on the proposed 

Yucca Mountain repository includes the 

opportunity for adjudicatory hearings conducted 

by the NRC.

• The LSN is an electronic system that can be 

accessed through the Internet by anyone.

• The LSN contains the documents that 

may be used as evidence in the NRC licensing 

proceeding.

• The LSN meets the NRC’s document 

"discovery" requirements associated with the 

Yucca Mountain repository hearings spelled out 

in Title 10 of the Code of Federal Regulations,

Part 2, Subpart J. 

• The LSN is the single place where the parties 

and potential parties to the licensing hearing 

can search for materials from any or all of 

those parties’ documentary collections in a 

uniform way.

• Public availability of the LSN was a key feature 

of a 1988 negotiated rulemaking that established 

the system.

Who May Enter

Documents on the LSN?

• The parties and potential parties to the hearing 

make their documents that may be used 

as evidence in the NRC licensing proceeding 

available via the LSN. Non-parties or nonpotential parties may not enter documents.

Who May Use the LSN?

• There are no restrictions. Any Internet user 

worldwide can use the LSN to access Yucca 

Mountain repository licensing documents.

• Parties to the proceeding have priority access 

as needed to meet hearing schedules using user 

ID’s and passwords. Priority users also have the 

ability to save their searches.

• No ID’s or passwords are needed by the public.

How Do I Use the LSN?

• Log on to the LSN Internet web site at 

www.lsnnet.gov.

• There is an easy to use "simple search" for 

new users and an "advanced search" for power 

searching.

• For a simple query, just type in the word or 

concept for which you are looking.

• Advanced searches allow you to "zero in" on 

authors, dates, and other specific data.

• If you find a document exactly on your 

topic, try the "like search" feature to bring 

up more documents on the same topic.

• Most documents have full text. Others, like 

maps and diagrams, may have only images. 

Directions to download plug-ins to view all 

allowable file types are available online for 

standard browsers.
