Perhaps you should try some spelling variations:
"stable spent reactor" » "stable shunt reactors", "stable event reactor", "stable sweet reactor", "stable spectra reactor"
"stable salt reactor" » "stable fast reactor", "stable shunt reactor", "stable a reactor", "table salt reactor", "stable small reactor", "stable self reactor"
"stable set reactor" » "stable jet reactor", "stable test reactor", "stable set reaction", "stable sets reactor"

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (((("stable salt reactor") OR ("stable set reactor"))) OR ("stable spent reactor")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"stable salt reactor\") OR (\"stable set reactor\"))) or (\"stable spent reactor\"))".
• Removing quotes may allow a broader search: (((( stable salt reactor ) OR ( stable set reactor ))) or ( stable spent reactor )).
• Adding a wildcard symbol may retrieve word variants: (((("stable salt reactor") OR ("stable set reactor"))) or ("stable spent reactor"))*.
