"What happened at Visakhapatnam has nothing to do with the Navy. It was an industrial accident," DRDO Director General Avinash Chander said.
Talking to reporters on the sidelines of a function, Chander said a DRDO team at the accident site right now was inspecting and it would take probably another week to exactly analyse, reported media.
"Also, we have to see whether there was a human error which caused this or any equipment. That's why it will take some time and our team are on the job," he said.
The Scientific Advisor to the Defence Minister said when components are made, they go through various levels of testing before they are cleared for use. "Therefore, there was this system, which was getting tested. Naturally, when you test, there can be malfunctions."
"We are going to ensure that whatever causes we will find, appropriate measures will be taken to ensure that such events will not take place. A higher level of safety will be incorporated," the Defence Secretary (R&D) said.
One person was killed and two injured in an accident at a site of under-construction nuclear submarine at Eastern Naval Command in Visakhapatnam on March 8.
The incident took place when the pressure of the hydraulic tank of the Arihant class submarine was being tested and the tank's lid fell on the workers of L&T at Building-5 of the ship building centre.
