摘要
壓水式反應器的燃料在運轉一個週期後，需移出部份舊燃料束來進行新燃料裝填的工作。以往是由經驗豐富的工程師完成佈局設計，使佈局符合安全規範，並追求最大的經濟效益。近年由於計算機計算速度進步許多，可使用電腦程式來執行自動搜尋燃料佈局。本研究室曾利用蟻群演算法結合塔布搜尋發展自動化搜尋程式，但整體過程計算時間與仍有改善空間，本研究使用量子啟發式演算法結合塔布搜尋進行佈局設計，以達到減少計算時間的目標。 本研究之自動化程式以C語言撰寫，在UNIX系統利用爐心模擬程式SIMULATE-3計算爐心狀態。本研究使用三種方法，一是單獨使用量子啟發式演算法以三維計算進行搜尋；二是使用量子啟發式演算法結合塔布搜尋，其中進行三維爐心計算；三是使用量子啟發式演算法以二維計算週期初爐心狀態，然後以三維爐心計算進行塔布搜尋，燃料佈局設計流程先以量子啟發式演算法取得粗略的燃料佈局，再藉由塔布搜尋方法微調佈局中的燃料位置，以滿足設計要求。本研究以馬鞍山核電廠一號機19週期的燃料佈局作為驗證目標，搜尋符合限值的佈局，並達到縮短計算時間的目標。

In a pressurized water reactor (PWR), the fuel assemblies must be reloaded after operating for a period of time. Usually, loading pattern (LP) was designed by experienced engineer and LP should satisfy the safety requirements. Recently, the computer capability is greatly improved and thus it is possible to design LP automatically by computer code. Our laboratory had applied the combination of ant colony algorithm and tabu search to design LP, however, the computing time is rather long. In this research, quantum-inspired evolutionary algorithm (QEA) incorporated with tabu search were adopted to design LP and reduce computing time. The C language was used to develop the computer program and the core states was calculated by SIMULATE-3 under UNIX environment. In this research, we use three methods to search the LP. Firstly, QEA was used alone. Secondly, the combination of QEA and tabu search were adopted with 3D core status calculation. Lastly, the combination of QEA with 2D calculation to find the proper initial LP at the begin of cycle and then tabu search with 3D calculation to find the final LP. The LP of Maanshan nuclear power plant unit one cycle 19 was chosen as the design target, the satisfactory LP was found and also the computing time was reduced.
