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 spent reactor") OR ("stable set reactor")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"stable salt reactor\") or (((\"stable spent reactor\") OR (\"stable set reactor\"))))".
• Removing quotes may allow a broader search: (( stable salt reactor ) or ((( stable spent reactor ) OR ( stable set reactor )))).
• Adding a wildcard symbol may retrieve word variants: (("stable salt reactor") or ((("stable spent reactor") OR ("stable set reactor"))))*.
