  • Ensuring Compliance: Helps writers verify their word choices against ASD-STE100 specifications, ensuring documentation meets international standards for technical English.
  • Quick Reference: Offers instant lookups for approved words, nuclear engineering terminology, and standard abbreviations, reducing the time spent searching through specification documents.
  • Automated Quality Checks: Provides API endpoints that enable integration with documentation tools for automated STE compliance checking and terminology validation.

About ASD-STE100

ASD-STE100 (Simplified Technical English) is an international specification for technical English writing, originally developed for aerospace and defense industries. It is maintained by the ASD Simplified Technical English Maintenance Group (STEMG). Valar Atomics applies these standards to nuclear engineering documentation.

The specification provides:

  • A controlled vocabulary of approximately 900 approved words
  • 60+ writing rules for grammar and style
  • Guidelines for creating clear, unambiguous technical documentation
  • Standards for technical term usage and abbreviations

STE was developed to help readers whose first language is not English understand technical documentation more easily. It also improves clarity and reduces ambiguity for all readers.
