Grove Software

What Grove Software does

Grove Software is a division of privately held Grove Engineering, Inc., headquartered in Lynchburg, Virginia, and has operated continuously since 1992 (with firmographic records dating the current entity to 2005). The company develops and sells Windows-based scientific software for radiation shielding design and dose assessment, targeting health physicists, nuclear design engineers, radioactive waste managers, nuclear facility operators, and academic institutions. Its four core products are MicroShield (available in Pro and LT versions), MicroShield V&V, MicroSkyshine, and RadDecay, sold individually or as the Grove Software Suite bundle.

The technology stack is built on proprietary 3D solution algorithms for photon/gamma ray shielding supporting 16 geometry configurations, drawing on NUREG/CR-0781 and Kansas State University research for skyshine analytics, and incorporating extensive nuclear and material data libraries (ICRP 38, ICRP 107, NIST, ANSI/ANS-6.4.2-2006, and 497 standard nuclides plus optional ICRP-107, ICRP-38, and MIRD decay libraries). The MicroShield V&V add-on supports user-side software qualification for regulatory certification, and the products reference US nuclear regulatory frameworks (10CFR50 Appendix I, 40CFR190).

Grove Software operates an annual subscription licensing model with individual and site license tiers, distributes exclusively through direct sales (website, email, fax order forms), and uses a multi-tier training program (Fundamentals, Specialist, Expert Certification with AAHP/ABHP pre-approved CHP continuing education credits) as both a revenue stream and a customer enablement channel. The company is founder/privately owned, employs 1–10 people, and shows no disclosed external funding, M&A, or leadership change activity.

Revenue model

1. Software Subscription Licenses: Grove Software sells software as annual subscription licenses. The software is leased for a one-year term with quotations available for longer terms. Subscription licenses include access to support services and all new versions of the software as they are released as long as the subscription is active. Both individual licenses (single machine) and site licenses (multiple installations within a geographic region) are offered for all products including MicroShield Pro, MicroShield LT, MicroShield Pro V&V, MicroSkyshine, and RadDecay.

Core offering

Grove Software develops and sells specialized radiation shielding and dose assessment software used by health physicists, nuclear engineers, and radioactive waste managers. The product suite includes MicroShield (photon/gamma ray shielding with 3D solution algorithms), MicroShield V&V (verification and validation package), MicroSkyshine (sky-scatter dose calculations), and RadDecay (radioactive decay and nuclide data). The company also offers training and certification services supporting these tools.

Product overview

Grove Software is a radiation shielding and dose assessment software company offering a suite of specialized scientific applications. The portfolio consists of four core products: MicroShield® (a comprehensive photon/gamma ray shielding and dose assessment program available in Pro and LT versions), MicroShield® V&V (a verification and validation add-on for certification support), MicroSkyshine® (for calculating photon dose from sky scattered gamma radiation), and RadDecay® (for displaying radioactive decay information). The products can be purchased individually or as the Grove Software Suite bundle. All products are Windows-based desktop applications sold as annual subscription licenses with support services and version updates included.

Broad incumbents

• Mirion Technologies: Mirion (including CANBERRA) is a global incumbent across radiation detection, dosimetry services, and radiation protection software (including RadCalc dose assessment products). It overlaps with Grove's shielding and dose calculation use cases from a much broader portfolio reach, serving many of the same nuclear facilities and health physicists.
• ORTEC (AMETEK): ORTEC, part of AMETEK, supplies radiation detectors, spectroscopy systems, and gamma-ray analysis instrumentation widely used by nuclear facilities and health physicists. While primarily hardware-focused, it addresses overlapping customers with integrated software for shielding and dose evaluation.
• Thermo Fisher Scientific: Thermo Fisher's Radiation Measurement & Security Instruments business sells radiation detection hardware and supporting software used by nuclear facilities and health physicists. It overlaps with Grove's dosimetry and shielding workflows at the enterprise customer level despite being a much larger diversified instrumentation player.

Others

• LANDAUER: LANDAUER is a leading radiation dosimetry services and monitoring provider (now part of Fortive). It is not a direct software competitor but operates alongside MicroShield in the same health physics workflow and is often a buyer/influencer for adjacent radiation protection software tools.
• RSICC (Radiation Safety Information Computational Center): RSICC at Oak Ridge distributes and curates nuclear transport and shielding codes (e.g., SCALE, MCNP, point-kernel codes) used by the same nuclear design engineer audience as MicroShield. It is a free/governmental ecosystem alternative rather than a commercial competitor but shapes Grove's addressable market.

Direct peers

• ATTILA Solutions: ATTILA provides deterministic nuclear particle transport and dose-rate simulation software used for shielding design and dose assessment in nuclear facilities. It competes directly with MicroShield for engineering-grade shielding calculations and serves a similar nuclear design engineer customer base.
• Nucleonica GmbH: Nucleonica is a nuclear science software portal offering nuclide data, decay calculations, and dose/risk assessment tools. It overlaps with RadDecay and parts of the MicroShield workflow and serves the same health physics and nuclear engineering audience, making it the closest like-for-like niche software peer.
