Grove Software has a verification and validation (V&V) package available for the MicroShield® software.
The overall purpose of the MicroShield® V&V package is to furnish documentation and software as an aid to users in their internal software qualification or verification and validation.
The verification and validation package provides the following:
1. The V&V test plans and results for user records.
2. User may repeat the tests for comparison and further evidence.
3. Traceability for the nuclear and material data used in the program.
4. A means to exercise routines to verify that calculations are done properly.
Specifically, the MicroShield® V&V package includes:
1 – The MicroShield® Validation Report. This report consolidates a myriad of information sources used over the years for development of MicroShield®, many of which would be difficult to find by users. Specific verification and validation sections are included. The report also contains the V&V test plan and results and the user instructions for MicroShield® V&V software application. Historical test results are included in appendices for traceability and completeness.
2 – The MicroShield® V&V Software. A program that independently exercises various MicroShield® processing routines and displays the data files that are provided. This software provides evidence that the internal workings of the program are being done correctly and allows independent verification.
The MicroShield® V&V Package must be purchased separately from MicroShield®. The MicroShield® V&V package is now sold as individual licenses, Local Area Site Licenses, or Wide Area Site Licenses.

MicroSkyshine® calculates the photon dose from sky scattered gamma ray radiation.
MicroSkyshine® has been used to evaluate conformance with 10CFR50, Appendix I ALARA requirements as well as 40CFR190 fuel cycle exposure criteria.
Typical application would be to determine scattering from BWR turbine buildings, radwaste storage facilities, and waste disposal sites.
MicroSkyshine’s® analytical method of solution is based on the use of “beam functions” for a point source. This method was developed for NUREG/CR-0781 (May 1979), which resulted from an NRC sponsored effort. However, MicroSkyshine® reflects the efforts of analysts at Kansas State University, who further improved the method.
特色
MicroSkyshine’s® Technical Features
- A variety of silo and wall geometries. MicroSkyshine® accepts dimensional data in meters, centimeters, feet, or inches.
- The scattering medium is air, and the Berger method is used for calculating buildup in an overhead shield. Any one of seven materials can be selected for this purpose.
- Library data for radionuclides, attenuation, and buildup are included.
- Source decay can be calculated and daughters generated.
- As many as twenty energy groups (with an energy range of 100 keV-10 MeV) may be created; total concentration entries are automatically converted to curies.
- All calculations performed by MicroSkyshine® assume that the silo wall or vertical wall is a perfect shield; that is, radiation through the walls will not be calculated.
Geometries Included
- Point Source Behind A Wall
- Horizontal Line Source Behind A Wall
- Horizontal Rectangular Area Source Behind A Wall
- Horizontal Circular Area Source Behind A Wall
- Vertical Line Source Behind A Wall

RadDecay® is an interactive program for displaying radioactive decay information for any of the radionuclides in the libraries. RadDecay® comes with the standard Nuclide Library of 497 nuclides and three optional libraries (ICRP-107, ICRP-38 and MIRD). Data displayed includes the half-lives, radioactive daughter nuclides, probabilities per decay, and decay product energies for alphas, betas, positrons, electrons, X-rays, and gamma rays. RadDecay® also generates displays, plots, and printouts for composite beta spectrum data.
RadDecay® conducts decay calculations for a single nuclide or a set of nuclides. For a single nuclide, given an initial activity and decay time by the user, RadDecay® will calculate the remaining activity of the nuclide and the activity of its progeny. The decay chain is calculated and displayed for as many as 20 generations. Identical daughter nuclides generated along different branches of the decay chain are alternately combined and displayed. Decay chain and decay curves can be readily displayed and printed. Users can display information by clicking on any nuclide in the displayed decay chain.
rddmain2-thumb1RadDecay® also conducts decay calculations for a set of nuclides and generates a summary report for viewing, printing and saving. The user also has the option to set the minimum activity reported. RadDecay® searches its library and reports the corresponding nuclides for photons, alphas, betas, electrons, or positrons within user-defined energy and half-life ranges. Among the improvements and enhancements relative to prior versions are:
- Multiple-nuclide decay calculations, individual set and in batches.
- Choice of units for input and output of multiple-nuclide decay calculations.
- Improved graphics display and printing.
- Improved user interface, ease of operation with shortcuts.
- Ability to copy multi-nuclide decay results to clipboard for importing into spreadsheet and word processing documents.
- Additional three optional nuclide libraries made available (ICRP-107, ICRP-38 and MIRD)
- Expanded and improved search performance.
- Feature to allow user to select desired print font, flexibility in configuration.
- Compatibility with international date formats.
- Modified data structure for improved performance.
- Ability to display data for multiple nuclides.
- Ability to display information about any nuclide displayed in a decay chain.
