South China Regional Office completes pre-critical nuclear safety inspection for Yangjiang Nuclear Power Plant overhaul

From September 14 to 17, the South China Regional Office of Nuclear and Radiation Safety Supervision of the Ministry of Ecology and Environment (hereinafter referred to as the South China Regional Office) organized an inspection team to conduct a pre-critical nuclear safety inspection of Unit 5 of Yangjiang Nuclear Power Plant for its sixth refueling overhaul (Y506 overhaul). This inspection was jointly carried out by the Nuclear Facility Business Division and the newly established Operation Special Division, adopting an organizational model of two-division coordination and complementary expertise to systematically verify the safety status of the unit after refueling and before criticality, thereby safeguarding the critical juncture for the safe startup of the unit. The criticality of the unit after overhaul is a link in the nuclear safety management chain where risks are highly concentrated. With core refueling and loading completed, and maintenance, modification, and periodic testing items concluding in a concentrated manner, equipment status, personnel operations, and operational decisions converge at this point. The South China Regional Office closely focused on the core proposition of "whether the unit truly possesses the conditions for safe operation," concentrating on key contents such as operating limits and conditions, availability of safety-important items, confirmation of post-maintenance equipment status and periodic test results, closed-loop rectification of outstanding issues from the previous overhaul, and handling of abnormal conditions, insisting on item-by-item verification and one-by-one clearance to ensure that no doubts are carried forward and no loose ends are left.

Taishan Nuclear Power Achieves Full-Process Digitalization for Two Major Environmental Monitoring Inspections

Recently, the central station inspections of the Plant Environment and Meteorological Monitoring System (KRS) and the Hydrological and Water Quality Monitoring System (YSI) buoy inspections at Taishan Nuclear Power Plant have officially entered full-process digital operation, with all related inspection tasks integrated into the GFIS (Taishan Inspection Data Monitoring System) for online workflow, marking the end of the paper-based inspection sheet era. In the central station equipment room of the environmental laboratory, inspectors can complete online data entry and upload via mobile office devices after verifying data accuracy. △Inspection interface Previously, these two inspection tasks relied on paper-based recording, with inspection data manually transcribed on site and handed over offline for review, making real-time verification and sharing of information impossible. The mountains of paper forms not only made data retrieval time-consuming and laborious but also hindered equipment operation and maintenance quality assessments. Driven by the company's digital transformation initiative, these two inspection tasks have now embarked on the path of digitalization.
