Incidents in Heavy Water Plant - lessons to learn

I chanced to come across an old paper by Mr Kanthiah, Mr Vaidyan and Mr Bhowmick of Heavy water plant, Tuticorin about incidents that occurred in the heavy water plant. The lessons are valid even today. The incidents discussed are:
1. Rupture of ammonia cracker tubes
2. Water entry in a cable junction box thru nitrogen line. (A nitrogen hose connected to a boiler filled with DM water allowed water to enter the nitrogen line when nitrogen supply failed)
3. Potassium amide splash on personnel due to choking of line upstream of vent wth solid potassium amide
4. Synthesis gas booster compressor trip due to malfunction of seal oil level transmitter.

Read details of the incidents in this link.
