Book excerpt: Martin Marietta Energy Systems, Inc. (MMES) is committed to performing and documenting safety analyses for facilities it manages for the Department of Energy (DOE). Safety analyses are performed to identify hazards and potential accidents; to analyze the adequacy of measures taken to eliminate, control, or mitigate hazards; and to evaluate potential accidents and determine associated risks. Safety Analysis Reports (SARs) are prepared to document the safety analysis to ensure facilities can be operated safely and in accordance with regulations. Many of the facilities requiring a SAR process fissionable material creating the potential for a nuclear criticality accident. MMES has long had a nuclear criticality safety program that provides the technical support to fissionable material operations to ensure the safe processing and storage of fissionable materials. The guiding philosophy of the program has always been the application of the double-contingency principle, which states: {open_quotes}process designs shall incorporate sufficient factors of safety to require at least two unlikely, independent, and concurrent changes in process conditions before a criticality accident is possible.{close_quotes} At Energy Systems analyses have generally been maintained to document that no single normal or abnormal operating conditions that could reasonably be expected to occur can cause a nuclear criticality accident. This application guide provides a summary description of the MMES Nuclear Criticality Safety Program and the MMES Criticality Accident Alarm System requirements for inclusion in facility SARs. The guide also suggests a way to incorporate the analyses conducted pursuant to the double-contingency principle into the SAR. The prime objective is to minimize duplicative effort between the NCSA process and the SAR process and yet adequately describe the methodology utilized to prevent a nuclear criticality accident.

Book excerpt: 'This regulatory document is part of the CNSC's safety analysis series of regulatory documents, which also covers deterministic safety analysis and probabilistic safety assessment. ... Regulatory document REGDOC-2.4.3, Nuclear Criticality Safety, sets out requirements for nuclear criticality safety and provides guidance on how those requirements may be met. It provides information for the prevention of criticality accidents in the handling, storage, processing and transportation of fissionable materials and the long-term management of nuclear waste. This document clarifies the minimum physical constraints and limits on fissionable materials in order to ensure nuclear criticality safety during the construction, operation, decommissioning, or abandonment of the licensed facility and with respect to the handling, storing, processing and transportation of certain fissionable materials. It applies to operations with fissionable materials outside nuclear reactors, except for the assembly of these materials under controlled conditions (such as in critical experiments)'--Preface, page i.

Book excerpt: Mass volume limits are frequently used in the Separations Areas recovery operations where precise modelling may not be feasible or justified. Mass volume limits also provide a quick, ready and conservative reference to Nuclear Safety personnel when called upon for guidance. Specifically, New Special Recovery Personnel requested mass volume limits directly applicable to the Sample Handling operations. Earlier Nuclear Safety Analysis by J.L. Forstner provided limits at 0%, 2% and 4% 24°Pu that could be applied but were in graphical form and the actual data for the 2% 24°Pu log-log curve could not be found. Further, recently concerns were expressed as to operations personnel reading log-log plots, extracting meaningful information and directly applying as nuclear safety limits. Data included in the attached charts and tables is the author's attempt to remedy this condition. Table 2 provides mass volume limits that can be extracted in part or completely and directly applied to the Nuclear Criticality Safety Supplements and operating procedures. Figures 1 through 7 are for the purists who prefer graphical representations.

This book was released on 2009 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the challenges that today's new workforce of nuclear criticality safety engineers face is the opportunity to provide assessment of nuclear systems and establish safety guidelines without having received significant experience or hands-on training prior to graduation. Participation in the International Criticality Safety Benchmark Evaluation Project (ICSBEP) and/or the International Reactor Physics Experiment Evaluation Project (IRPhEP) provides students and young professionals the opportunity to gain experience and enhance critical engineering skills.

Book excerpt: The S-Area Defense Waste Processing Facility (DWPF) can process all of the high level radioactive wastes currently stored at the Savannah River Site with negligible risk of nuclear criticality. The characteristics which make the DWPF critically safe are: (1) abundance of neutron absorbers in the waste feeds; (2) and low concentration of fissionable material. This report documents the criticality safety arguments for the S-Area DWPF process as required by DOE orders to characterize and to justify the low potential for criticality. It documents that the nature of the waste feeds and the nature of the DWPF process chemistry preclude criticality.
