The secret 'paint factory' and its radioactive pond

In 1947 the Soviet Union began building Combine No. 7 at Sillamäe, code-named the 'Paint Factory'. It was in fact a top-secret uranium enrichment plant, and Sillamäe was a closed town from 1947 to 1991. In almost 50 years the plant left 12 million tonnes of radioactive waste in a pond of 40 hectares, 24 to 26 metres high and in one place only 30 metres from the sea. Uranium, thorium and arsenic seeped into the Gulf of Finland, dust blew over the town and radon rose from it. A storm could have breached the dam. A clean-up of about 20 million euros, launched around 1999, sealed and covered it. The pin, by the harbour, is approximate.

1947. aastal hakati Sillamäele rajama NSV Liidu Kombinaati nr 7 koodnimega „Värvivabrik“. Tegelikult oli see rangelt salastatud uraani rikastamise tehas ning Sillamäe oli aastatel 1947 kuni 1991 kinnine linn. Ligi 50 aastaga jättis tehas 12 miljonit tonni radioaktiivseid jäätmeid 40-hektarisse hoidlasse, mis oli 24 kuni 26 meetrit kõrge ja kohati vaid 30 meetri kaugusel merest. Uraan, toorium ja arseen imbusid Soome lahte, tuul kandis tolmu linnale ja hoidlast eraldus radooni. Torm oleks võinud tammi purustada. Umbes 1999. aastal alanud ja ligikaudu 20 miljonit eurot maksnud projektiga hoidla isoleeriti ja kaeti. Märk sadama lähedal on ligikaudne.
