I'll go sentence by sentence. Let's take the first line: "Apply the developed models to various applications, including nuclear power generation, nuclear medicine, and astrophysics." Here, "Apply" is the first word to replace. Then "developed models" → "created models|established models|formulated models". "various applications" → "diverse fields|multiple uses|different areas". "including" → "encompassing|involving|covering".
Now, construct the output with the synonyms formatted correctly. Make sure that each replaced term is in v2 format. Proper nouns remain as is. Only the text is output, no markdown or extra text. 4.2.1 project modeling nuclear reactions
Re-reading the query: "convert every word with 3 variants in format opt1. Proper nouns stay. Only output text." So each individual word (token) except proper nouns. So for example, the sentence "Apply the developed models to various applications," each word "Apply", "the", "developed", "models", "to", "various", "applications", etc., except if it's part of a proper noun.

References: The authors and journal titles are proper nouns, so they stay. The years and page numbers are also not to be changed. Make sure that each replaced term is in v2 format
First part:
Original: Nuclear power plants rely on nuclear reactions to generate electricity.
Moving to the next bullet point: "Limited Experimental Data". "Limited" can be scarce, minimal, restricted. "Experimental data" – empirical measurements, test results, lab findings.
