Power Plant Digitization

The 540 MW TAPP-3, a totally indigenous nuclear power unit, is the 16th nuclear power reactor in the country. It has been designed and built by the Nuclear Power Corporation of India Limited (NPCIL), a public sector after undertaking under the Department of Atomic Energy (DAE). Unit 3 of the Tarapur Atomic Power Project (TAPP-3) attained its first criticality on the 21st May, 2006.

The achievement of criticality was a major milestone in the project completion process. It signified the start of a self-sustaining nuclear fission chain reaction in the reactor core. The criticality of Unit 3 came about two months ahead of schedule. Unit 4, the predecessor of Unit 3, achieved criticality on 6th March, 2005. Tarapur Atomic Power Project Units - 3&4 (TAPP - 3&4) comprise of two Pressurized Heavy Water Reactor units (PHWRs) having 540 MW each. The PHWRs use both natural uranium fuel and heavy water as moderators and coolants respectively. TAPP - 3&4 were built in the shortest time than any other PHWRs in India. This gestation period is comparable to international benchmarks.

The Challenge TAPP 3&4 is located 200 km from Mumbai, the entire campus is of more than 2 km radial and civil infrastructure was constructed in a phased manner. The challenge was keep the campus in line with the latest civil infrastructure, IT investment and deployment.

The Solution
SCCI associate partner, Insight was approached for a solution design and the whole turnkey project.

Server Solution: As the project was conducted in a phased manner, the IT requirement was very dynamic and was not well defined, and since the project was working in a 3-shift availability, manageability was a key decision maker. The company has positioned the Intel-based Xeon server from Compaq/HP ProLiant which have gave them a great expandable solution, highly available, scalable and ease of manageability.

Backup Solution: Being in a remote location data management was on top priority. Solutions were to be easy to manage and deploy, support heterogeneous platforms and certain applications on HP UNIX, Novell and Microsoft. Insight had supplied and integrated HP autoloader with Net Vault’s Backbone solution which gave them flexibility in terms of O.S. and database.

Connectivity Solution: The plant is 200 km away from Mumbai and the project should be working round the clock. The local telco Service provider was not having any connectivity, hence monitoring plant activity from TAPP Township which is 20 km away from the site and also the Mumbai office which is approx. 250 km from site and certain location within site were not having any wired connectivity. Insight provided a CISCO Remote Access Solution with a secured login name and password with limited access to network depending upon the credentials. Besides deploying Wi-Fi for connecting various temporary office setups, Insight has also created a secured internet access to the entire plant by offering a mix of security of CISCO PIX and WatchGuard UTM solution. The company laid more than 20 km of OFC by providing more than 30 segments on campus in addition to delivering more than 40 km of CAT6 with 350+ networking.
