1 From Global Fissile Material Inventories, June 2004.

2 These values are updates of the estimates in India’s and Pakistan’s Fissile Material Inventory, end of 1999, by David Albright, October 2000.

3 The values presented are the median and 5th-95th percentiles (in parentheses), calculated using the forecasting software Crystal BallÆ.  This software allows a more systematic and defensible uncertainty analysis.

4 India has been working on building a gas centrifuge plant for many years.  The status of the project is rarely discussed in public, although progress should have been made.  There has not been any public indication that the project was cancelled. Not enough public information exists to determine whether a significant amount of HEU has been produced in the facility or, if so, to estimate the size of an HEU stock.  Nonetheless, based on the age of the project, India may now be producing HEU in significant quantities, perhaps enough to make both fission and thermonuclear weapons.
