Testimonials

I am writing to let you know how much we here at ICN appreciate your friendly cooperation and timely suport in our projects that involved the use of PORFLOW code.

PORFLOW has been purchased by the Institute for Nuclear Research for specific tasks carried in our Geological Disposal Safety Assessment Group. We used the code for groundwater flow and contaminant transport calculations, both in internal projects and in the 5 years long IAEA's Coordinated Research Project (T 02.10.24). The modeling work was summarized in the IAEA tecdoc 1717 (http://www-pub.iaea.org/MTCD/Publications/PDF/TE-1717_web.pdf).

Your professionalism and positive attitude are greatly appreciated; thank you again.

For the purpose of sefety assessment of Near Surface Disposal Facility, NPCIL purchased 'PORFLOW' software form "M/S ACRi Infotech Pvt. Ltd., Bangalore". A three dimensional groundwater flow and contaminant transport cases were simulated on 'PORFLOW' software Results of these simulations helped to complete the safety assessment study.

The support and help given by M/S ACRi team during 'PORFLOW' installation, training, trouble shooting and technical queries is worth mentioning. NPCIL decided to use this software for further upcoming studies of ground water flow and contaminant transport.

PORFLOW is SRNL's porous medium flow and transport code of choice for groundwater flow simulation and radiological performance assessment. PORFLOW is distinguished by its abilities to simulate first-order (radionuclide) decay and progeny ingrowth in both liquid and solid, and accommodate user-specified changes to material properties during transient transport. We use the latter to model physical and chemical degradation of engineered materials over time. We also use the algebraic grid calculation feature to extend PORFLOW's built-in capabilities with customized add-ons. PORFLOW's free-form input using high-level keywords enables us to build models at more of a conceptual level, and minimizes pre- and post-processing effort.

The PORFLOW computer code developed by ACRI has been is use for over 30 years in varied applications. Over the years, I and my team have used the code in many applications, ranging from simple to very complex problems that dealt with groundwater resource development, groundwater quality management, and long-term and large-scale simulations of variably saturated heterogeneous and fractured rock. The code has the capability of simulating coupled flow, heat transfer, and chemical transport in complex geometry aquifers. The four most important things to know about this code are
(1) developing an input file is very easy because a freeform command language using format free "keywords" is used for creating it; and
(2) the code has a modular structure so that, advanced users having access to the source code can easily adapt it to unique problems;
(3) the built in matrix inversion algorithms are very efficient so that the run times are short; and
(4) it has built in graphics routines that can provide graphic output in addition to the usual tabular output. I wholeheartedly recommend the code to beginners as well as experienced users.

My association with Computational fluid dynamics virtual reality institute, Dharamshala (Academic wing of M/S ACRI infotech Pvt. Ltd., Bangalore) was on account of two collaborative projects funded by Board of Research in Nuclear Sciences. During this collaboration, we worked on developing aerosol dynamics module for integration with 'ANSWER' software.

The knowledge and skill of their team members was helpful to fulfil the objectives of both projects. Not only the team is expert in terms of software skills, the mathematical foundations of team members are appreciable. The support given by them during different steps of the concluded projects consisted of technical discussions, training, demonstrations, trouble shooting, validation exercises etc. We are keen to work on other projects with them in future.

Cigéo is Andra’s main project which aims at disposing of high level and intermediate level long-lived radioactive waste packages in a deep geological repository, located at 500 meters deep in clay layer at East of France.

Andra is involved in carrying long-term performance and safety assessment, which consists of quantifying release and transfer of radionuclides in solution from the waste packages to verify that the impacts on the environment and on human beings over the next million years will remain below the regulatory limits.

To fulfill this objective, Andra performs safety calculations which require use of numerical tools likely to quantify solute transfer in porous media within disposal repository and geological media, with specific hydraulic and transfer properties. Andra has been using Porflow for more than 20 years, as it still offers all the numerical and physical features required for our models, with good performance both in terms of accuracy and computation time. This is why when Andra has to assess the robustness of some results with different software, Porflow is chosen as the reference. Its robustness, solvers libraries, powerful Freeform language and versatility are extremely appreciated among the users.
