Standard Guide for Gamma Radiation Shielding Performance Testing
5.1x00a0;Shielding performance testing should be performed to verify analytical predictions of shielding effectiveness, compliance with design requirements, and determine the location(s) of shielding deficiencies that may require either supplemental shielding, design modification, or changes to operating methods and procedures to resolve. 5.2x00a0;Dose rates higher than adjacent shielding may be expected in the vicinity of master-slave manipulator penetrations as a result of cable or tape clearance requirements within the mechanisms where they pass through the shield walls. This is true even with supplemental shielding installed in the manipulator through tube. 5.3x00a0;Similar to manipulator penetrations, when sources are placed directly in front of penetrations and gaps resulting from access doors or panels, radiation levels directly on the other side of the gaps or penetrations may be higher than levels in adjacent shielding or analytical predictions. If these test configurations are representative of how the shielded enclosure will actually be operated (that is, the test configuration is representative of engineered source and normally occupied work locations) than the additional expense of designing or modifying the shielded enclosure should be considered if that location is normally occupied and will result in a significant increase of dose rates to personnel. 5.4x00a0;Frames around shield windows may have a higher potential for shielding deficiencies. 5.5x00a0;Shield walls constructed of concrete may be subject to the formation of void spaces that could result in diminished shielding performance. 5.6x00a0;Background radiation levels in the area where the dose measurement data are being gathered shall be monitored and their contribution to measured dose rates accounted for in the data analysis as part of the test report. 1.1x00a0;This guide identifies appropriate test methods for determining the sufficiency of radiological shielding for hot cells and shielded enclosures. 1.2x00a0;After constructing or modifying radiological shielding, it is necessary to verify that shielding performance meets or exceeds the shielding performance requirements. This is typically accomplished using sealed test sources of much less activity than the design basis. This allows for modifications or correction of any discrepancies identified before the commissioning of the hot cell. 1.3x00a0;The guidance and practices recommended by this guide are applicable to both new and existing shielded facilities and enclosures for evaluating shielding suitability and locating the existence of shine paths or other shielding anomalies that result from design, manufacture, or construction. 1.4x00a0;Two types of testing may be performed. 1.4.1x00a0;Shielding performance verification testing provides evidence that the shielding configuration is sufficient for meeting established performance criteria and for identifying......

4.1x00a0;Usesx2014;This guide is intended for use on a voluntary basis by parties who wish to conduct a VES on a parcel of real estate to determine if a VEC is identified for the TP (that is, the presence or likely presence of COC vapors in the vadose zone of the TP caused by the release of vapors from contaminated soil and/or groundwater either on or near the TP as identified by the Tier 1 or Tier 2 procedures in this guide). The process defined in this guide is a screening process that requires information similar to information generally collected as part of a Practice E1527 Phase I ESA as well as additional information described in subsection 5.3 and Section 8 of this guide. If a VEC is identified by this screening process, the user may conduct further investigation. This guide, however, defines a procedure for determining in connection with a property involved in a real estate transaction whether a VEC exists or does not exist. A x201c;VEC existsx201d; determination is appropriate, for example, when there is known COC contamination in, at or on the TP, such as may be the case when COC-contaminated groundwater exists in the subsurface of the TP. A x201c;VEC does not existx201d; determination is appropriate, for example, when subsurface sampling has confirmed that COCx2019;s are not present. The guide can be applied to property with existing structures, property with structures that will be substantially rehabilitated, property without existing structures but having planned structures (for example, property in development), or property without existing structures and with no planned structures (for example, undeveloped property with no planned development). 4.2x00a0;Clarifications on Use:x00a0; 4.2.1x00a0;Use in Conjunction with Practice E1527 Phase I ESAx2014;This guide, when used in conjunction with Practice E1527

1.1 This practice describes test methods and data analyses used to develop models for the prediction of the long-term behavior of materials, such as engineered barrier system (EBS) materials and waste forms, used in the geologic disposal of spent nuclear fuel (SNF) and other high-level nuclear waste in a geologic repository. The alteration behavior of waste form and EBS materials is important because it affects the retention of radionuclides by the disposal system. The waste form and EBS materials provide a barrier to release either directly (as in the case of waste forms in which the radionuclides are initially immobilized), or indirectly (as in the case of containment materials that restrict the ingress of groundwater or the egress of radionuclides that are released as the waste forms and EBS materials degrade).1.1.1 Steps involved in making such predictions include problem definition, testing, modeling, and model confirmation.1.1.2 The predictions are based on models derived from theoretical considerations, expert judgement, interpretation of data obtained from tests, and appropriate analogs.1.1.3 For the purpose of this practice, tests are categorized according to the information they provide and how it is used for model development and use. These tests may include but are not limited to the following:Attribute tests to measure intrinsic materials properties,Characterization tests to measure the effects of material and environmental variables on behavior,Accelerated tests to accelerate alteration and determine important mechanisms and processes that can affect the lifetime licensed performance of waste form and EBS materials,Service condition tests to confirm the appropriateness of the model and variables for anticipated disposal conditions,Confirmation tests to verify the predictive capacity of the model, andTests or analyses performed with analog materials to identify important mechanisms, verify the appropriateness of an accelerated test method, and to confirm long-term model predictions.1.2 The purpose of this practice is to provide methods for developing models that can be used for the prediction of materials behavior over the long periods of time pertinent to the service life of a geologic repository as part of the basis for performance assessment of the repository.1.3 This practice also addresses uncertainties in materials behavior models and their impact on the confidence in the performance assessment.This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory requirements prior to use.

This test method measures the system material properties of an insulated formed heat shield under invehicle conditions. While the material properties of the individual components can often be determined via existing test methods, the system properties of the entire composite is typically much harder to ascertain (especially for multi-layer shields). System material properties include thermal conductivity in the lateral or in-plane (x) direction, thermal conductivity through the thickness or perpendicular (y), surface emissivity on the top and bottom sides of the shield and specific heat of the shield material. All properties are determined for the entire shielding material specimen as a composite of the entire structure. Properties are determined using a testing apparatus that allows for two-dimensional heat flow through the specimen. Due to this, the material property results from this test method may not agree with one-dimensional heat flow type testing methods, but is representative of most heat shield materials performance tested with a centralized heat source. Therefore, material property results from this test method may be more suited for multi-dimensional analytical studies. This standard sets forth the general guidelines to construct and operate the testing apparatus to acquire a satisfactory set of test data. Designs conforming to this standard are included and must not be deviated from for sensitivity reasons that will be discussed in more detail later. Test parameters that cannot be deviated from include, but are not limited to; specimen size, distance between the source and the specimen, source diameter and environmental conditions around the apparatus. This method ultimately determines the shield material properties by using the test data along with an analytical scheme, see Section 8.1. This test method will evaluate both isotropic and anisotropic insulated shielding materials. This may also include multi-layer shielding structures which include embossed/corrugated solids, porous, fibrous, granulated and coated materials.

Diese Internationale Norm legt die Grundlagen fur den Aufbau des Gerates und Mindestanforderungen test, die fur die Bestimmung der stationaren Warmedurchgangseigenschaften von Bauteilen und ahnlichen Ausrustungen für technische Zwecke im Laboratorium einzuhalten sind. Sie legt jedoch keinen speziellen Aufbau fest, da die Anforderungen, speziell an die Dimensionierung, zu einem geringeren Teil auch in bezug auf die Betriebsbedingungen, ausgesprochen verschieden sind. Diese Internationale Norm beschreibt weiterhin das Ger?t, die Me?technik und die notwendige Datenangabe. Spezielle Bauteile, zum Beispiel Fenster, erfordern zus?tzliche Verfahrensweisen, die nicht in dieser Internationalen Norm enthalten sind. Weiterhin sind Messungen des Einflusses von Feuchteübertragung oder -Umverteilung auf den W?rmestrom nicht enthalten, jedoch ist bei Aufbau und Betrieb der Einrichtung der m?gliche Einflu? der Feuchteübertragung auf die Genauigkeit und die Bedeutung von Prüfergebnissen zu berücksichtigen. Die Eigenschaften, die gemessen werden k?nnen, sind der W?rmedurchgangskoeffizient und der W?rmedurchla?widerstand. Es werden zwei alternative Verfahren angegeben: das Verfahren mit dem kalibrierten Heizkasten und das Verfahren mit dem geregelten Heizkasten. Beide sind für vertikale Probek?rper, wie z. B. W?nde, und für horizontale Probek?rper, wie z. B. Decken und Fu?b?den, geeignet. Die Dimensionierung der Ger?te kann so gew?hlt werden, da? Untersuchungen an Bauteilen in der natürlichen Dimensionierung m?glich sind. Die Verfahren sind haupts?chlich für Labormessungen gro?er inhomogener Probek?rper geeignet, obwohl selbstverst?ndlich auch homogene Probek?rper geprüft werden k?nnen, und diese sind für die Kalibrierung und die Validierung notwendig. Bei der Prüfung homogener Probek?rper nach dieser Internationalen Norm hat die Erfahrung gezeigt, da? im allgemeinen eine Me?genauigkeit von ± 5 % erreicht werden kann. Jedoch kann die Me?genauigkeit jedes einzelnen Ger?tes mit homogenen Referenzprobek?rpern, deren W?rmedurchla?koeffizienten den zu messenden Bereich abdecken, abgesch?tzt werden. Die Einsch?tzung der Me?genauigkeit für nichthomogene Probek?rper ist komplizierter und beinhaltet eine Analyse des W?rmestrommechanismus in den zu prüfenden speziellen Typen der inhomogenen Probek?rper. Derartige Analysen werden in dieser Internationalen Norm nicht behandelt. Das Verfahren berücksichtigt nicht Messungen mit Massenübertragung durch den Probek?rper w?hrend der Prüfung.
