How to Read the Domestic Nuclear Power Plant Map from Gori to Shinhanul

A regional guide that avoids confusing headquarters, units, and reactor types

When following news about domestic nuclear power plants, names like Gori and Shin-Gori, Hanul and Shin-Hanul often appear repeatedly. Headquarters manage multiple units in a region, a unit refers to an individual power generation facility, and reactor types distinguish how heat is produced and transferred. Mixing these three units can easily lead to confusion, such as misconstruing the status of a specific unit as the shutdown of the entire headquarters.

This list is structured to help you identify regions and reactor types by grouping Gori, Shin-Gori, Saewool, Wolseong, Shin-Wolseong, Hanbit, Hanul, and Shin-Hanul into unit clusters. Since the operational, maintenance, permanent shutdown, and construction statuses change over time, it's best to verify the publicly available operational information from Korea Hydro & Nuclear Power (KHNP) rather than relying on fixed tables.

Gori Units 3 and 4 are key items for understanding the composition of regional nuclear power plants in the domestic map. Simply put, Gori Units 3 and 4 refers to individual power generation facilities at the Gori Nuclear Power Headquarters in Busan, Gijang-gun. The fact that the headquarters is named Gori does not confirm the operational status of individual facilities. To understand the role of Gori Units 3 and 4, it’s important to consider not just the specific unit or device but also the surrounding systems and regulatory processes.

Common confusion regarding Gori Units 3 and 4 often arises when people equate them with Gori Unit 1’s current status. Words like 'shutdown', 'storage', or 'approval' in news related to Gori Units 3 and 4 do not automatically determine the cause of incidents or safety impacts. The status and numbers related to Gori Units 3 and 4 can vary by timeline, so it’s essential to cross-check with data from the same point provided by the operator and regulatory authorities.

When checking Gori Units 3 and 4, verify power generation, utilization rate, and operational rate for each unit separately. Then, record the title, posting date, target unit, and reference point from publicly available materials on Gori Units 3 and 4. Also, take a look to see if there are follow-up investigations or approval results. The first placement of Gori Units 3 and 4 is simply for reading flow and does not indicate a ranking of risk or importance. If you need to assess safety impacts, it’s necessary to check not just the explanation of Gori Units 3 and 4 but also the overall system's integrity and radiation measurement results together.

When reading the domestic nuclear power plant map, it's good to break down information into four columns: headquarters name, unit name, reactor type, and current status. For example, within the Wolseong headquarters, both Wolseong and Shin-Wolseong coexist, and they may have different reactor types. If you don’t group by just the regional name, you can grasp the generation capacity and maintenance news more accurately.

When confirming the current operational status of a power plant, don’t just look at the titles in search results; look at the operational information per unit and the announcement dates together. The meanings of terms like ‘shutdown’ and ‘storage’ can vary between regular maintenance and incidents, and permanent shutdowns indicate different scenarios. If you need to cite numbers or statuses, it’s safer to cross-check data from the same date provided by KHNP and the Nuclear Safety and Security Commission.
