About
Built from nuclear project experience. Designed around evidence.
DjedCore is a nuclear licensing, quality and traceability company. We provide independent licensing and quality services, and we are developing licensed desktop software that helps organisations prove that what they deliver is acceptable.
01
Vision
Every nuclear component can show what it is, how it was made and whether it is acceptable for its exact place in the plant, without chasing records by hand. New reactors are licensed on verified evidence instead of last-minute paperwork.
Mission
We close the traceability gap between owners, EPC contractors, vendors and subcontractors, so that the evidence licensing depends on is complete, consistent and verifiable. We do this through independent licensing and quality services, and through licensed desktop software that runs on our clients' own systems, backed by our technical support.
02
What we hold to
Evidence before assertion
A status is only as good as the record behind it. We show the record.
Your data stays yours
The software runs on your devices. We do not host, regulate or approve your work or your documents.
Reactor-neutral
One shared core for large reactors and SMRs. Family-specific rules live in versioned configurations.
Compliant by design
Every engagement and every licence is screened for export control, including US 10 CFR Part 810, before any technical exchange.
Plain language
Findings that an engineer, a manager and an inspector can all act on.
Knowledge for newcomers
Countries building their first plant deserve the lessons others have already paid for.

Why “Djed”
The djed is one of the oldest symbols of ancient Egypt: a pillar of stacked layers that stands for stability and endurance. Our software follows the same idea: eight layers of traceability, from law and licence down to a single evidence record, stacked so that the whole structure holds.
Eight layers of traceability
- L1Law and regulation
- L2Licence and licence conditions
- L3EPC contract
- L4Design basis
- L5Codes and standards
- L6Specifications and issued-for-construction drawings
- L7Inspection and test plans
- L8Evidence records
04 / Why DjedCore
Built by a licensing engineer who learned software.
Most nuclear licensing tools are built by software engineers who learned the regulations. DjedCore was built the other way round.
The difference is in what it is designed to produce: not a draft that a consultant rewrites, but structured, traceable evidence that a regulator can verify and a supplier can defend, built on the documentation discipline of a large VVER-1200 new-build project.
Evidence, not inference
Every finding must trace to an objective record, not to AI inference or a consultant's memory.
Reactor-neutral
Designed for large reactors and SMRs, because licensing traceability is a documentation problem, not a reactor-physics problem.
Need-to-know by design
Regulators see what they need. Vendors protect what they must. Controlled information is designed to stay within its authorised boundary.
Your systems, your evidence
Installed on your own devices. Your evidence never leaves your organisation, and your licensing basis stays yours.
How it works is available under NDA to qualified clients.

Mohamed H. Salem
Founder and CEO · Technical lead, licensing and software
- CQI/IRCA ISO 9001 Lead Auditor
- ISO 19443
- VVER-1200 licensing documentation
- SMR and advanced-reactor safety review
- MSc, MEPhI
- Doctoral research, Cairo University
Mohamed sets DjedCore's direction and owns its technical method: the eight layers of traceability, the evidence model and the software architecture. Every engagement and every release is held to the standard of nuclear new build: if a claim cannot be traced to objective evidence, it does not leave DjedCore.
Nuclear licensing and quality engineer. Contributed to licensing documentation for a large VVER-1200 new-build project, and performed independent reviews of safety analysis reports for small modular and advanced reactors at a national atomic energy authority. CQI/IRCA-certified ISO 9001 Lead Auditor with hands-on ISO 19443 experience.
MSc in Nuclear Physics and Technology (MEPhI); doctoral research at Cairo University on accident-tolerant fuel in SMR cores. Works in Arabic, English and Russian.
