Methods of actuating a well tool can include releasing chemical energy from at least one portion of a reactive material, thermally expanding a substance in response to the released chemical energy, and applying pressure to a piston as a result of thermally expanding the substance, thereby actuating the well tool, with these steps being repeated for each of multiple actuations of the well tool. A well tool actuator can include a substance contained in a chamber, one or more portions of a reactive material from which chemical energy is released, and a piston to which pressure is applied due to thermal expansion of the substance in response to each release of chemical energy. A well tool actuator which can be actuated multiple times may include multiple portions of a gas generating reactive material, and a piston to which pressure is applied due to generation of the gas.

1. An actuator for actuating a tool in a well, comprising: a non-explosive reactive material configured to release chemical energy when activated, wherein the non-explosive reactive material comprises a mixture of two reagents and is connected to and communicable with a first chamber;a substance located in the first chamber and thermally expandable by the release of the chemical energy from the non-explosive reactive material; anda piston in pressure communication with the well and to which pressure is applied due to the thermal expansion of the substance in the first chamber. 2. The actuator of claim 1, wherein the substance is compressible by hydrostatic pressure in the well. 3. The actuator of claim 1, wherein the piston is displaceable in response to the applied pressure. 4. The actuator of claim 1, wherein chemical energy is releasable from one or more portions of the non-explosive reactive material individually. 5. The actuator of claim 1, wherein the chemical energy released from the non-explosive reactive material in a first portion of the non-explosive reactive material causes thermal expansion of the substance in the first chamber, and chemical energy released from the non-explosive reactive material in a second portion of the non-explosive reactive material causes thermal expansion of the substance in a second chamber. 6. The actuator of claim 5, wherein the piston is displaceable in a first direction in response to thermal expansion of the substance in the first chamber, and the piston is displaceable in a second direction opposite to the first direction in response to thermal expansion of the substance in the second chamber. 7. The actuator of claim 5, further comprising a passage configured to equalize pressure across the piston. 8. The actuator of claim 1, wherein the non-explosive reactive material comprises a thermite mixture. 9. The actuator of claim 8, wherein the thermite mixture comprises powdered aluminum and at least one of iron oxide, copper oxide, or a combination thereof. 10. The actuator of claim 8, wherein the substance comprises at least one of nitrogen gas or water. 11. An actuator for actuating a tool in a well, comprising: a piston in pressure communication with the well;a thermally expandable substance located on a side of the piston in a chamber; anda non-explosive reactive material configured to release chemical energy when activated and to thermally expand the substance to apply pressure to the side of the piston, wherein the non-explosive reactive material comprises a mixture of two reagents and is connected to and communicable with the chamber. 12. The actuator of claim 11, wherein the piston is displaceable in response to the applied pressure. 13. The actuator of claim 11, wherein gas is generated from multiple portions of the non-explosive reactive material individually. 14. The actuator of claim 11, wherein gas is generated from multiple portions of the non-explosive reactive material sequentially. 15. The actuator of claim 11, wherein the piston is displaceable in a first direction in response to generation of gas from a first portion of the non-explosive reactive material, and the piston is displaceable in a second direction opposite the first direction in response to generation of gas from a second portion of the non-explosive reactive material. 16. The actuator of claim 11, further comprising a passage configured to equalize pressure across the piston. 17. The actuator of claim 11, wherein the non-explosive reactive material comprises a thermite mixture. 18. The actuator of claim 17, wherein the thermite mixture comprises powdered aluminum and at least one of iron oxide, copper oxide, or a combination thereof. 19. The actuator of claim 17, wherein the substance comprises at least one of nitrogen gas or water. 20. An actuator for actuating a tool in a well, comprising: a non-explosive reactive material configured to release chemical energy when activated;a substance located in a first chamber and thermally expandable by the release of the chemical energy from the non-explosive reactive material;a piston in pressure communication with the well and to which pressure is applied due to the thermal expansion of the substance in the first chamber;wherein the chemical energy released from the non-explosive reactive material in a first portion of the non-explosive reactive material causes thermal expansion of the substance in the first chamber; andwherein chemical energy released from the non-explosive reactive material in a second portion of the non-explosive reactive material causes thermal expansion of the substance in a second chamber.
