Stable form of Plutonium discovered accidentally

Scientists led by Helmholtz Zentrum Dresden Rossendorf have found new compound of Plutonium unexpectedly in France. The team was actually trying to create plutonium dioxide nano particles using different precursors. In the process, the plutonium at its pentavalent state showed a peculiar behavior. The scientists then learnt that the strange behavior of Plutonium at its pentavalent state was because it was stable! The team confirmed its stability using Pu M4 edge technology.

The experiment was repeated after 3 months and the element showed the same behavior. The scientists thus confirmed that Plutonium exhibited stability properties at its pentavalent state.

Significance

  • The unstable radioactive dangerous plutonium that is predominantly used in nuclear applications are tricky to transport, store and dispose.
  • The scientists were in the process of creating Plutonium Dioxide as it is relatively stable as compared to other radioactive materials. It does not dissolve in water
  • The major drawback of Plutonium waste is that when dumped underground, they contaminate water table to a radius of 10 km.

CGWB inks MoA with IISc for development of ground water flow models

The Central Ground Water Board (CGWB) has inked Memorandum of Agreement (MoA) with Indian Institute of Science (IISc), Bengaluru for Development of ground water flow models and preparation of aquifer management plans for parts of Karnataka.

Key Facts

This mathematical model is being developed as part of aquifer mapping and management programme. It will help for better understanding of existing groundwater scenarios, predicting response of groundwater system to various stress conditions expected to arise in future and developing effective management plans incorporating different demand and supply side interventions.

IISc will prepare final study report that will include data analysis, conceptualisation and model study plan, hydrogeological setting, sensitivity analysis, groundwater related issues and response of groundwater system to different scenarios and block-wise management plans.

Central Ground Water Board (CGWB)

CGWB is multidisciplinary scientific organization under Ministry of Water Resources, River Development & Ganga Rejuvenation. Its mandate is to develop and disseminate technologies and monitor and implement national policies for scientific and sustainable development and management of India’s ground water resources.

It is vested with responsibilities to carry out scientific studies, monitoring of ground water regime, exploration aided by drilling, management and regulation of country’s ground water resources. It also undertakes exploration, assessment, conservation, augmentation, protection of groundwater system from pollution.
