NPCIL Clarifies KKNPP Leak: Only Conventional Data, Not Nuclear Systems

NPCIL clarified that leaked drawings from a breach at Reliance Infrastructure pertain only to conventional Balance of Plant facilities, not nuclear safety systems. The EPC contract for KKNPP Units 3 and 4 was awarded in 2018 through a public tender. The company shared indicative drawings with bidders during the tendering process. NPCIL confirmed the designs were accepted after technical review and do not involve nuclear security information.

NPCIL clarifies leaked KKNPP drawings cover only conventional BoP facilities, not nuclear security systems

New Delhi, July 16

State-run Nuclear Power Corporation of India Limited clarified that the drawings reportedly leaked through a breach at Reliance Infrastructure Ltd. in connection with the Kudankulam Nuclear Power Project relate only to conventional Balance of Plant facilities and not to any nuclear safety or security systems, as per a statement by NPCIL.

The clarification came in response to media reports regarding an alleged data leak linked to KKNPP Units 3 and 4. NPCIL said the Engineering, Procurement and Construction (EPC) contract for the Common Services-Balance of Plant (BoP) package was awarded to Reliance Infrastructure Ltd. in 2018 through a public tender process.

"With reference to reports circulating in the media regarding the Kudankulam Nuclear Power Project (KKNPP) Units 3 & 4, it is clarified that the Engineering, Procurement and Construction (EPC) contract for the Common Services - Balance of Plant (BoP) package was awarded to M/s Reliance Infrastructure Ltd. in 2018 through a Public Tender process," it said.

According to NPCIL, the scope of the EPC contract covers engineering, procurement and supply, construction, and commissioning of common service facilities.

It added that the facilities are conventional in nature, similar to those used in thermal power plants and other process industries, and are not connected to nuclear safety or nuclear security systems.

Adding that company had shared indicative drawings and technical specifications with bidders during the public tendering process, the release said, "Based on these inputs and the requirements of the project, the EPC contractor, M/s Reliance Infrastructure Ltd., prepared detailed engineering drawings in consultation with the respective Original Equipment Manufacturers (OEMs)."

The designs were accepted by NPCIL after technical review.

"NPCIL reiterates that the information claimed to be available in the public domain pertains only to conventional Balance of Plant (BoP) common service facilities and does not relate to any nuclear safety- or nuclear security-related systems or information," the release said.

Reliance Infra should have been more careful with data handling, no matter how conventional the drawings are. In today's world, any leak can be weaponized by misinformation campaigns. The government needs to audit all contractors handling such projects.

As someone who works in engineering, I understand that balance of plant systems are just pumps, pipes, and cooling towers — nothing sensitive. But the media should be responsible before running scary headlines about nuclear leaks. It creates unnecessary panic.

I still think we need to be transparent. If it's just BoP, then why did it take so long for NPCIL to come out with a statement? Anyway, let's hope our cyber systems for nuclear plants are world-class. Kudankulam is vital for our energy needs. ⚛️

This reminds me of similar 'leaks' in other countries that turned out to be nothing. Our nuclear establishment is one of the most professional in the world. But the opposition will try to make political capital out of this — standard procedure. 🙄

I appreciate the clarification but I'm still concerned about how these drawings ended up online. Even conventional data can reveal vulnerabilities if someone knows what to look for. India needs stronger data protection laws and better enforcement against leaks.
