It was commonly called "Hector." It was constructed starting in 1958 in a temporary construction area, which is now called "B" Area. This is near the intersection of SRS roads "2" and "C." It is identified as Building 770-U. It has a cylindrical structure with a hemispherical dome. Its diameter is 70 ft (21.3 m) with a height of 125 ft (38.1 m). About 60 ft (18.3 m) is located underground. The building was designed to contain an internal pressure of 24 psig (165 kPa). It had a 70 MW thermal output. It was built to test the concept of a heavy water moderated and cooled reactor for civilian power. It was tested from late 1962 to December 1964.〔(Savannah River Site at 50 ) HWCTR is described on p. 353 - 355.〕 It was not restarted. The fuel was removed and the facility was secured by 1971. All auxiliary buildings were removed. The reactor building awaits its final disposition.〔(Savannah River Site Long-Term Stewardship Report ) Status of decommissioning.〕〔(SRS Citizen Advisory Board Recommendation No. 44 )〕 During deactivation activities at the HWCTR in 2010, an unanticipated high dose was experienced during the removal of wire flux monitor cabling. On November 2, 2010, when work was in progress to remove the instrumentation, one of three small helium-filled ion chambers was removed from the instrumentation sleeve. A higher than expected dose rate was detected when the lowest of the three ion chambers exited the reactor vessel below the lower axial shield. As a result, three workers received whole body doses of 2.52 mREM, 2.7 mREM, and 5.6 mREM.〔(Unanticipated, High Dose During the Removal of Wire Flux Monitor Cabling from the HWCTR Reactor Vessel ) (D&D KM-IT Lessons Learned)〕 ==References== 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Heavy Water Components Test Reactor」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
