Nuclear message in a plastic bottle

By Jay Fang 方儉

If we want to learn about nuclear power safety here in Taiwan, we might find the answer in a simple plastic bottle.

President Ma Ying-jeou (馬英九) recently said that when it comes to the Fourth Nuclear Power Plant in Gongliao District (貢寮), New Taipei City (新北市), it is important to listen to people’s opinions, conduct thorough research, communicate, make careful decisions and carry out plans effectively. However, considering that the plant’s construction site does not even have a restroom, it is not likely that nuclear safety will ever become a reality in Taiwan.

More than two decades ago when I was interviewing people about the first three nuclear power plants, which had only been up and running for a few years, I discovered that the plants were plagued by the reactors randomly tripping.

Analysis of these incidents showed that, apart from the inevitable problems caused by natural events like earthquakes and typhoons, their biggest cause were things like malfunctioning circuit board control cards and overheating in the reactor units. Further analysis of these causes showed that many of the situations that were put down to “unknown causes” were actually due to “uric acid.”

What do circuit boards at a nuclear power plant have to do with uric acid? First I thought those problems were caused by mice, but later an engineer secretly told me that it was because there was no restroom at the plants’ construction sites, so workers would go to the toilet wherever they could — often against the walls. Their urine then turned into uric acid which seeped into and corroded the circuit boards. The result was irregular signals or lost control of the signals.

When a nuclear power plant trips, operations stop for several days. According to Taiwan Power Co (Taipower), the company loses NT$100 million (US$3.4 million) each day when a plant is down.

Forty years ago, sanitary and lifestyle habits were different, and lack of toilet facilities was in line with the times.

Here, I am reminded of a joke about a punctuation mark: There was once a house owner who became very frustrated because people were urinating on his wall so he put up a notice on the wall reading: “Pedestrians and others may not urinate here” (行人等不得在此小便). Little did he expect that the number of people urinating there would keep on increasing, because someone had added a comma to the original sentence, which changed the notice to: “Pedestrians who cannot hold on may urinate here” (行人等不得,在此小便).

I remembered this anecdote after the recent discussions about safety and the quality of construction at the Fourth Nuclear Power Plant.

I asked a person who had worked on the construction of the plant if there were toilets there. He gave me a wry smile and then sent me a photo, with a note that said the photo was taken at a section of the wall of one of the plant’s containment vessels.

I realized the picture was that of a plastic bottle cemented into the wall.

Things have indeed progressed since the time of the first three power plants: Workers now urinate into plastic bottles and throw them into the containment vessels while they are being filled with cement.

I am sure we could apply to the UN for World Heritage status for this plant. Apart from the plastic bottles and their contents, there is much other rubbish cemented into the wall and, regardless of whether we apply for World Heritage status or any other cultural status, we really should make sure that a record is kept of this.
