This article considers best practices for writing articles in science, technology, and policy, focusing on writing for international scholarly journals in nuclear security. Its two main audiences are technical communication educators/researchers and internationals wishing to publish their work in English-medium scholarly journals. I discuss publishing scenarios and challenges facing such authors and offer guidelines for producing clear, effective, publishable articles, in English, for international discourse. My approach is based on traditional rhetorical principles, plain language studies, research pursued at nuclear security conferences, feedback from internationals at writing workshops, and my experience as editor of the "International Journal of Nuclear Security."
