Editing Nevada Test Site (section)

===Area 3===
Area&nbsp;3 held 266 nuclear tests for a total of 288 detonations, including Upshot-Knothole 'Harry',  more than in any other area of the site.<ref name="DOE/NV-209" />

As part of [[Operation Tinderbox]], on June 24, 1980, a large satellite prototype ([[Defense Satellite Communications System#DSCS II|DSCS III]]) was subjected to radioactivity from the "Huron King" shot in a vertical line-of-sight (VLOS) test undertaken in Area&nbsp;3. This was a program to improve the database on nuclear hardening design techniques for defense satellites.

The final nuclear test detonation at site was [[Operation Julin]]'s "Divider" on September 23, 1992, just prior to the moratorium ending all nuclear testing.<ref name="Gross">{{cite journal|last1=Gross|first1=Daniel A.|title=An Aging Army|journal=Distillations|date=2016|volume=2|issue=1|pages=26–36|url=https://www.sciencehistory.org/distillations/magazine/an-aging-army|access-date=March 20, 2018|archive-date=March 20, 2018|archive-url=https://web.archive.org/web/20180320230842/https://www.sciencehistory.org/distillations/magazine/an-aging-army|url-status=live}}</ref> Divider was a safety experiment test shot that was detonated at the bottom of a shaft sunk into Area&nbsp;3.

In 1995 and 1997, plutonium-contaminated soil from "Double Tracks" and "Clean Slate 1" of [[Operation Roller Coaster]] (1963) was picked up from the [[Tonopah Test Range]] and brought to the Area&nbsp;3 Radioactive Waste Management Site as a first step in eventually returning Tonopah Test Range to an environmentally neutral state. Corrective action regarding the contaminated material from the "Clean Slate&nbsp;2" and "Clean Slate 3" tests has yet to be agreed upon.<ref name="DOE/NV-1046">{{cite web |url=http://www.nv.doe.gov/library/factsheets/DOENV_1046.pdf |title=Plutonium Dispersal Tests at the Nevada Test Site |author=National Nuclear Security Administration / Nevada Site Office |date=April 2010 |work=Fact Sheets |access-date=December 2, 2011 |url-status=dead |archive-url=https://web.archive.org/web/20110927020910/http://www.nv.doe.gov/library/factsheets/DOENV_1046.pdf |archive-date=September 27, 2011 }}</ref>
