title="부분 편집: 역사"><span>편집</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>가봉은 프랑스 식민지로, 1956년 <a href="/wiki/%ED%94%84%EB%9E%91%EC%8A%A4" title="프랑스">프랑스</a>의 원자력청이 오클로 지역에서 우라늄 광석을 발견하였다. 프랑스는 즉시 <a href="/wiki/%EB%AC%B4%EB%82%98%EB%82%98" title="무나나">무나나</a> 마을 근처에 프랑스빌 우라늄 광산회사 (Comuf, Compagnie des Mines d'Uranium de Franceville)라는 우라늄 광산을 열고 광대한 광물자원을 캐내기 시작하였으며, 가봉에는 회사의 지분을 소수 주었다. </p><p>40년 동안 프랑스는 가봉지역에서 우라늄을 채광했으며, 이 우라늄은 프랑스와 유럽 등지에서 전력생산용으로 쓰였다. 가봉의 우라늄 광부들은 그들 덕택에 프랑스의 <a href="/wiki/TGV" title="TGV">TGV</a>가 작동할 수 있었다고 반농담삼아 말하곤 했다. 현재 지금은 우라늄 광산은 소진되어 광산은 더 이상 운영하지 않는다. 최근에는 광산 운영의 영향으로 매립 작업이 이뤄지고 있다. </p><p>72년 프랑스 원자력청은 오클로 우라늄 광산의 시료를 검사하던 중 오클로의 우라늄 광산이 <a href="/wiki/%EC%84%A0%EC%BA%84%EB%B8%8C%EB%A6%AC%EC%95%84_%EC%8B%9C%EB%8C%80" title="선캄브리아 시대">선캄브리아 시대</a>때 천연원자로로 가동했다는 사실을 공표하였다. 오클로 광산에서 캐낸 우라늄의 시료 중에 다른 우라늄 시료보다 <a href="/wiki/%EC%9A%B0%EB%9D%BC%EB%8A%84-235" title="우라늄-235">우라늄-235</a> 함량이 낮은 시료가 있었던 것이다. 처음에는 이 시료에 <a href="/wiki/%EC%97%B4%ED%99%94_%EC%9A%B0%EB%9D%BC%EB%8A%84" class="mw-redirect" title="열화 우라늄">열화 우라늄</a>이 섞여들어갔을 것이란 추측을 하였지만, 시료의 동위원소를 분석한 결과 오클로 지역의 시료에서 핵분열시 생기는 동위원소 비율이 높다는걸 발견하였다. 연구를 진행하던 도중 지질학자들은 20억년 전에 가동한 원자로 화석을 찾아내었다. 이 시기에 우라늄 광석에 포함된 우라늄-235는 약 3%였으며, 물이 중성자 감속재 역할을 했다는 사실이 밝혀졌다. 천연원자로에서 물로 인해서 중성자가 전달되어 임계반응이 일어나게 되는 것으로 밝혀졌으며, 임계반응이 가속화되어 연쇄반응이 격렬해졌을때는 연쇄반응으로 생긴 열로 인해서 물이 증발하여 임계반응이 정지되었는 것으로 밝혀졌다. </p><p>이들 천연원자로는 1972년부터 1985년까지 오클로 광산에서 12개가 발견되었으며, 오클로 천연 원자로중 6개의 원자로에서 방출된 총에너지의 계산치는 약 6,000,000 MWd인데, 이 수치는 현재의 1000 MWe급 원자력발전소의 원자로 5기를 전출력으로 1년간 운전하였을 때에 발생한 열에너지와 대략 같다.<sup id="cite_ref-1" class="reference"><a href="#cite_note-1"><span class="cite-bracket">[</span>1<span class="cite-bracket">]</span></a></sup> </p> <div class="mw-heading mw-heading2"><h2
