South Africa's nuclear regulator disclosed on July 16 that Koeberg Power Station had three airborne-contamination events on June 30, July 2 and July 7, each following a loss of power to ventilation units during maintenance and remaining inside the plant [1]; the disclosure date must not erase the earlier event dates.

The paper's July 15 account of slowing Legionnaires' cases refused to turn improvement into an all-clear; Koeberg likewise requires no off-site release and three internal failures to remain visible together.

Workers who may have been exposed were screened, and the regulator said recorded contamination was below the radioactivity associated with a dental X-ray [1], but that comparison is not a worker-by-worker dose table; the regulator also reported no off-site radiological consequence and said the events did not meet its criteria for a nuclear or radiological emergency.

No auditable same-day X post was recovered, so meltdown-panic and nothing-happened feed counterframes remain unobserved; three contained events do not establish a public emergency, but containment does not erase repeated ventilation-power failures or possible internal exposure.

Koeberg's two reactors supply about 5% of South Africa's electricity [1], but that national role does not convert an unfinished inspection into an all-clear, and inspections were continuing at cutoff [1]; the missing record includes root cause, the number and doses of screened workers, ordered corrections and deadlines, and evidence that recurrence risk has closed, so reassurance and concern both need the same boundary of no reported public leak and no completed all-clear.
