中文摘要 | 台電核一、二廠沸水式核能機組在面臨第二個十年換照時重要的課題之 一即是反應爐內部組件結構應力腐蝕龜裂老化分析預測、監視、檢測、控制、改 善等管理策略的制訂與組合運用。本文先介紹應力腐蝕龜裂老化現象尚未充分考 量於現有設計限制內,或目前尚未獲得足夠檢測、試驗、修復、更新、破裂力學 結構完整餘裕分析評估等老化管理技術的GEBWRs爐心底板、爐心側板、爐心噴 灑內管、頂部導架、Dissimilar Attachment Weld等之後,僅從水化學改善單方面評 估以飼水注氫方法徹底改善爐水腐蝕環境的老化管理策略應用在台電BWRs之需 要性與可行性。 評估結果顯示核一、二廠反應爐內之爐心底板、部份爐心側板、及底部Dissimilar Attachment Weld等不易更換組件焊道在電廠運轉20年後的結構完整性可藉由及時 的加氫水化學來繼續確保。 |
英文摘要 | An effective plant-specific stress corrosion crackingaging management program of inspection, testing, monitoring,repair, refurbishment, analytical evaluation, and water che- mistry improvement on BWR internals will be an essential partof the whole package for Chinshan and Kuosheng to preparefor the application of their secondly ten-year LicenseRenewal. A preliminary component assessment of SCC susceptibility was taken on GEBWRs' Core Support Plate,CoreShroud, Core Spray Internal Piping, Top Guide.and DissimilarAttachment Welds for the combinations of components andSCC degradation mechanism are not satisfactorily managed bygeneric industry program.thereafter necessity and feasibilitystudies of Hydrogen Water Chemistry as an approach of waterchemistry improvement on TPC's BWRs have been reported inthis article. The results indicate that the structure integrity of CoreSupport Plate, partial Core Shroud,and Dissimilar AttachmentWelds of lower plenum for Chinshan and Kuosheng BWRscould be maintained for at least another ten years after 20years of operation, if a HWC implimentation has been made intime. |
