NPP_Kozloduy Kozloduy NPP Plc

NPP_Kozloduy Kozloduy NPP Plc, operator of Bulgaria's sole nuclear plant, holds AS210754. The public footprint is minimal—registry only, no routes. Evidence is limited to RIPEstat, the operator's website, WNA, and IAEA. Key uncertainties: true legal name, technical contacts, and operational routing. Watchpoints: prefix announcements, registry changes, technical disclosures. The profile offers a low-cost public indicator of digital posture changes in critical infrastructure.

NPP_Kozloduy Kozloduy NPP Plc

NPP_Kozloduy Kozloduy NPP Plc is the Bulgarian state-owned company that operates the Kozloduy Nuclear Power Plant, the country's only nuclear generating station. It also holds autonomous system AS210754 in the RIPE NCC registry, creating a rare public intersection between critical energy infrastructure and a visible internet number resource. The dual role enables open-source monitoring of its digital footprint, though current evidence is limited to registry presence and corporate disclosures.

Why It Matters

The current impact is moderate: AS210754 offers a publicly accessible indicator of network activity tied to a nuclear operator, but evidence is limited to registry visibility without active routing. If prefixes were announced or technical contacts surfaced, the intelligence value would rise sharply, reflecting a more operational digital presence for the plant.

What Public Sources Show

NPP_Kozloduy Kozloduy NPP Plc is the Bulgarian state‑owned company that operates Kozloduy Nuclear Power Plant, the country’s only nuclear generating station. It also holds autonomous system number AS210754 in the RIPE NCC registry, creating a rare public intersection between critical energy infrastructure and an internet number resource.

This dual role makes the company observable through both corporate disclosures and internet registry monitoring, though its digital footprint is currently limited to static registration data.

The ASN record provides an open‑source indicator of the operator’s network posture. Because Kozloduy is a single‑point electricity supplier and a nuclear site, any change in its digital surface — new prefix announcements, peering, or contact data — would be a signal worth tracking. Analysts can monitor AS210754 without privileged access, turning a free registry lookup into a low‑cost watchpoint for critical infrastructure.

RIPEstat lists AS210754 under the name “NPP_Kozloduy Kozloduy NPP Plc.” The company’s English‑language website confirms it runs the Kozloduy plant. The World Nuclear Association describes Kozloduy as Bulgaria’s sole operating nuclear power plant, and the IAEA’s Power Reactor Information System provides reactor statistics that corroborate the plant’s operational context. These sources together anchor the subject’s public identity and industrial role.

The verified public control surface is narrow. AS210754 is visible in registry data, but no active prefixes are currently announced, and no upstream, peer, or facility information is publicly documented. The company website does not disclose network architecture or technical contacts. The operating surface therefore consists primarily of the ASN registration and corporate web pages; broader internet infrastructure footprint remains unproven.

Two observable changes would materially alter the intelligence picture. First, the appearance of announced prefixes under AS210754 would indicate operational routing and possibly new connectivity. Second, updated WHOIS or RDAP records — especially if they introduce technical contacts or link the ASN to a recognised organisation entity — would strengthen the link between the registry entry and the plant operator. Either event would raise the subject’s digital relevance sharply.

The registered name contains duplication and an underscore, and no separate company registry filing confirms the exact legal name in English. No PeeringDB entry exists, no RIPE organisation entity ties AS210754 to the plant operator, and no technical personnel are publicly named. These gaps mean the current profile is registry‑backed identity, not an operational network assessment.

Until routing or richer organisation data appears, the digital footprint is best treated as a dormant registration that could become active.

Operating Surface

The company's public role spans two domains: an industrial operator responsible for Bulgaria's sole nuclear power plant, and a holder of an internet number resource (AS210754) listed in RIPE's RIPEstat. This dual role makes the company observable through both corporate disclosures and internet registry monitoring, though the digital footprint is currently limited to static registration data.

Changes to AS210754—such as new prefix announcements, contact record updates, or routing policy shifts—would provide a public signal about the network posture of a critical nuclear facility operator. Open-source intelligence can track this digital indicator without privileged access, making it a low-cost watchpoint for infrastructure analysts.

Watchpoints

The subject represents a critical infrastructure operator with a dormant internet numbering resource. The intelligence value currently lies in the potential for future signals; the absence of routing activity keeps the current relevance low. However, the overlapping of nuclear operations with a registrable digital identifier creates a unique monitoring opportunity that could yield early warning of network posture changes or operational shifts.

Concrete watchpoints include: (1) BGP announcements originating from AS210754, which would confirm active routing; (2) updates to the RIPE WHOIS or RDAP records that add technical contacts or link to an organisation entity; (3) appearance of a PeeringDB entry or upstream provider data; (4) any official corporate mention of network infrastructure in publications or tenders.

The main data gaps are: lack of verified legal name; no technical contact information; absence of operational routing proof; no upstream or peering data; and no direct organisational link between the ASN and the nuclear operator outside the registry name. Additional collection of company registry filings, network operator forums, and routing archives could strengthen the profile.
