Note (General): This report summarizes performances of core exit thermocouples (CETs) observed in 12 ROSA/LSTF tests which include ten small-break loss-of-coolant accident (SBLOCA) tests and two abnormal transient tests as an additional report to the OECD/NEA ROSA Project Test 6-1 report. The contents of this report are prepared to a task group which was set up to review and consolidate background knowledge of CET application to PWR accident management (AM) measures in April 2008 in the Working Group of Analysis and Management of Accident (WGAMA) at OECD/NEA. These tests cover wide ranges of test conditions such as size and location of break, primary pressure, core power, reflux water fall-back and operator actions. CET performances relative to the core temperature history are studied in each test, and general performances of CET are summarized focusing on the time delay and slow and low temperature excursion.
本報は、ROSA/LSTFで実施した12実験の炉心出口温度計(CET)特性をまとめたものであるが、これには10件の小破断冷却材喪失事故(SBLOCA)模擬実験と2件の異常過渡模擬実験を含み、既に検討されたOECD/NEA ROSAプロジェクト実験6-1の結果に対する追加資料として作成したものである。すなわちこの内容は、PWRアクシデントマネジメント策にCETを利用するうえで必要な知識基盤を再検討し統合するため、2008年4月に新たに設置されたOECD/NEA WGAMAのタスクグループに対して準備され、提出された。これらの実験は、破断サイズや位置,1次系圧力,炉心出力,リフラックス水流下の有無及び運転員操作等の広範囲の実験条件を含む。各々の実験について炉心温度履歴に対応するCET温度特性を調べ、時間遅れや温度上昇の緩慢さに焦点を当てたCETの一般特性をまとめた。
