The Apsara nuclear reactor is a research reactor located in the town of Trombay, near Mumbai, India. It was the first nuclear reactor to be built in India, and it has played a significant role in the country's nuclear research and development efforts over the years.
The Apsara reactor was designed and built by the Bhabha Atomic Research Centre (BARC), the primary nuclear research institute in India. It was commissioned in 1956, and has been in operation ever since. The Apsara reactor is a small, pool-type reactor that uses highly enriched uranium as fuel and heavy water as a moderator. It has a thermal power of 1 megawatt and a maximum thermal neutron flux of 4 x 10^12 neutrons per square centimeter per second.
One of the main purposes of the Apsara reactor is to serve as a platform for the development and testing of various nuclear technologies, including fuel fabrication, reactor instrumentation, and radiation shielding. It has also been used for the production of radioisotopes, which are used in a variety of medical and industrial applications.
Over the years, the Apsara reactor has undergone several upgrades and renovations to improve its capabilities and safety features. In the late 1990s, for example, the reactor was modified to allow for the testing of advanced fuels and materials, and in the early 2000s, it was equipped with a new control and instrumentation system. In addition, the reactor has been equipped with a number of safety features, such as a passive cooling system and a containment structure, to ensure the safety of the surrounding area and the operators of the reactor.
The Apsara reactor has contributed significantly to India's nuclear research and development efforts over the years, and it continues to be an important resource for the country's scientists and engineers. It has also played a key role in the development of India's nuclear energy program, which has grown significantly in recent years as the country seeks to meet its growing energy needs.
Rocket Boys: Inside the Apsara Nuclear Reactor
On account of being a pool reactor with a huge pool, testing the water was a major challenge, not to mention the fact that the actors had to walk across it and Sarbh even jumped into the water in one of the scenes. It is a hot water concept, which creates a difference between Apsara and Apsara-U. The upgraded reactor will increase indigenous production of radio-isotopes for medical application, it added. Along with these, Apsara is also useful for the production of isotopes, primary research, shielding experiments, neutron activation analysis, neutron radiography, and testing of neutron detectors.

However, following a major upgrade, anew version of Apsara has now been commissioned. On 4 th August 1956, the APSARA reactor attained criticality at 1545 hours. Studying macromolecular structures and protein-ligand interactions using biophysical techniques like X-ray crystallography, neutron-scattering, circular dichroism and synchrotron radiation, with an aim for ab-initio design of therapeutic molecules.

Retrieved 1 March 2018. As a part of upgrading, the existing highly enriched uranium HEU fuelled core is planned to be replaced with low enriched uranium LEU fuelled core in order to enhance the design safety features and the maximum available thermal neutron flux of the reactor. It is a multidisciplinary research centre for advanced research and development. The working of the reactor was another challenge—the purpose of every switch, toggle and lever needed to be understood and every mechanism needed to work perfectly. Better neutron economy The higher rated power has been attained with a new core design that achieves better neutron economy.
