Title	Accumulation of Sample Cylinders in the Chemistry Lab Exceeds Amount Allowed
Event Description	Event Summary: An amount of Uranium greater than that analyzed in the associated HAZOP [Hazardous Operation] for the Chemistry Laboratory is present in the laboratory. The HAZOP states that approximately 5 kg at any given time, and a maximum of 9 kg per year, will exist in the laboratory. This HAZOP was never updated for changes in customer orders and the resultant accumulation of 1S cylinders which has exceeded the original 9 kg limit. Nuclear Criticality Safety (NCS) staff have identified the condition as stable and safe. At no time were the enrichment levels or quantities of U235 in an unsafe condition. This is a condition different than that analyzed in the Integrated Safety Analysis (ISA). An NCS posting has been applied to prevent the removal or introduction of any material until a detailed evaluation of the condition and measures necessary for resolution are determined. Samples in 1S cylinders are provided to the Chemistry Lab which is located in the CRDB [Chemistry Receipt Dispatch Building] prior to shipment of product to the customer. Due to a slowdown in business these samples have accumulated to an amount exceeding the approved ISA which had not been updated to reflect current business practices. This condition was discovered by the MC & A [Material Control & Accounting] Group during a review of the process and will be addressed at an Emergency ISA Meeting on Monday, 3/30/15.
