Forgings for Small Modular Reactors — A Distinct Component and Certification Profile From Conventional Large Nuclear Plants
Shivam Forge manufactures forged components for the small modular reactor (SMR) sector — the emerging class of factory-fabricated, modular nuclear power designs with a component and certification profile genuinely distinct from conventional large-scale nuclear power plant construction.

Small modular reactors represent a genuinely different approach to nuclear power plant design and construction compared to the large, site-built reactors that have historically dominated the nuclear industry, and that difference carries through directly to the components involved. Where a conventional large nuclear plant is engineered and constructed largely as a unique, site-specific project with major components fabricated to order at a scale requiring some of the largest forgings made anywhere in industry, SMR designs are engineered around factory fabrication and modular assembly — smaller individual reactor units, in the range of tens to a few hundred megawatts rather than the thousand-plus megawatts typical of a conventional large reactor, designed to be manufactured in a repeatable factory process and transported largely complete to site, with several units potentially deployed together to reach a desired total plant capacity. This design philosophy shifts the component demand profile in a genuinely meaningful way: rather than a small number of extremely large, one-off forgings per project, SMR manufacturing favors a larger number of smaller, more standardized forged components produced repeatedly across a production run of reactor units, still subject to the same fundamentally rigorous nuclear-grade material traceability, non-destructive examination, and quality documentation expectations that apply to nuclear components generally, but within a different manufacturing and procurement rhythm than the bespoke, single-project sourcing pattern typical of conventional large-reactor construction. Several SMR designs also depart from conventional pressurized or boiling water reactor technology altogether, exploring alternative coolant approaches, which introduces its own distinct material compatibility and component considerations beyond what a conventional water-cooled reactor's balance-of-plant forgings require.
SMR designs are engineered for factory fabrication and repeated production across a series of reactor units, meaning component forgings are more standardized and produced repeatedly at a given specification rather than being sourced as bespoke, one-off items for a single unique large-reactor project.
Because individual SMR units are smaller in output than conventional large reactors, their forged components are generally smaller in individual scale as well — but a multi-unit SMR deployment, or multiple projects using the same standardized design, can generate meaningfully higher unit volume for a given component specification than a single large-reactor project would.
As with conventional nuclear plants, SMR balance-of-plant and auxiliary system forgings — valve bodies, pipe flanges, pump and heat exchanger components — represent a meaningful forging category distinct from the reactor's primary pressure boundary components, and typically the more accessible category for specialized forging suppliers to support.
Some SMR designs depart from conventional water-cooled reactor technology, exploring alternative coolant approaches — introducing material compatibility considerations distinct from conventional pressurized or boiling water reactor components, relevant to component specification for those specific designs.
The smaller individual component scale and more standardized, repeated production profile of SMR forgings doesn't reduce the underlying nuclear-grade material traceability and documentation expectations — full heat-to-part traceability and material certification remain foundational requirements, consistent with nuclear component sourcing generally.
Non-destructive examination requirements for SMR components are matched to the specific component's safety classification within the plant design, following the same tiered approach (primary pressure boundary versus balance-of-plant auxiliary systems) used across nuclear component classification generally.
Independent third-party material certification, where specified for a given component's safety significance, follows the same EN 10204 3.2-style independent witnessing practice used across nuclear component supply generally, regardless of whether the end reactor design is a conventional large plant or a small modular design.
Because SMR manufacturing favors repeated production of standardized components, documentation and qualification practice that supports consistent, traceable conformance across a production run — rather than a single bespoke qualification event — is a genuinely relevant consideration for SMR component sourcing.
Small modular reactors represent a genuinely different design and construction philosophy from the large, site-built nuclear power plants that have historically defined the nuclear industry, and understanding that difference is essential to understanding how SMR forged component demand differs from conventional large-reactor sourcing. A conventional large nuclear plant is engineered largely as a unique, site-specific construction project, with its major forged components — reactor pressure vessel forgings among the most demanding — fabricated to order at a scale among the largest single forgings made in any industry, sourced through a bespoke qualification and procurement process specific to that one project. SMR designs instead pursue smaller individual reactor units, generally in the range of tens to a few hundred megawatts of output rather than the thousand-plus megawatts typical of a conventional large reactor, engineered specifically for repeatable factory fabrication and modular assembly, with the intent of transporting largely complete reactor modules to site rather than constructing major systems in place.
This factory-fabrication design philosophy carries through directly to component sourcing patterns: rather than a small number of extremely large, one-off forgings procured for a single unique project, SMR manufacturing favors a larger number of smaller, more standardized forged components produced repeatedly across a production series of reactor units — and, because multiple SMR units may be deployed together to reach a desired total plant capacity, or because the same standardized design may be built across multiple projects, the cumulative unit volume for a given standardized component specification can meaningfully exceed what any single conventional large-reactor project would generate for an equivalent component category. This shift toward standardized, repeated production doesn't relax the underlying nuclear-grade quality expectations in any way — full material traceability from heat to finished part, non-destructive examination matched to each component's safety classification, and independent third-party certification where specified all remain foundational requirements, consistent with nuclear component sourcing practice generally, simply applied within a different production and procurement rhythm than bespoke single-project sourcing.
It's also worth noting that not every SMR design follows the same underlying reactor technology: while a substantial share of SMR designs are based on conventional pressurized or boiling water reactor technology scaled down and adapted for modular factory construction, some designs explore genuinely alternative coolant approaches distinct from conventional water-cooled reactor technology. Where that's the case, component material selection needs to account for that specific design's distinct coolant chemistry and operating conditions, rather than assuming direct equivalence with the material compatibility considerations relevant to a conventional water-cooled reactor's balance-of-plant components — a genuine, design-specific consideration worth confirming early in any SMR component sourcing discussion.
For engineering teams and procurement organizations working on SMR balance-of-plant and auxiliary system component sourcing — whether for a first-of-a-kind design still working through qualification, or for a standardized design entering repeated production — Shivam Forge applies the full nuclear-grade material traceability and documentation discipline this sector requires, adapted to SMR's specific standardized, repeated-production sourcing pattern.

Conventional large nuclear plants are largely unique, site-built projects requiring bespoke, often extremely large forgings sourced for that single project. SMR designs are engineered for factory fabrication and repeated production, meaning components are more standardized and produced across a series of reactor units, shifting the sourcing pattern toward repeated, higher-unit-volume procurement of smaller, more standardized forgings rather than one-off bespoke sourcing.
No — nuclear-grade material traceability, documentation, and non-destructive examination requirements remain fully in place for SMR components, matched to each component's specific safety classification within the plant design, consistent with nuclear component sourcing expectations generally regardless of overall reactor scale.
Not all of them — while many SMR designs are based on conventional pressurized or boiling water reactor technology at smaller scale, some explore alternative coolant approaches, which introduces distinct material compatibility considerations for the components in contact with that specific design's coolant and process conditions, relevant to material selection for those particular designs.
As with conventional nuclear plants, balance-of-plant and auxiliary system components — valve bodies, pipe flanges, pump shafts, and heat exchanger components — represent a meaningful and often more accessible forging category compared to the reactor's primary pressure boundary components, and follow broadly similar material and documentation practice adapted to each specific SMR design's parameters.
Yes. Provide your drawing or component specification, including the applicable safety classification and material standard, and our engineering team will confirm manufacturability, material recommendation, and quotation for your specific SMR component requirement.
