An alignment member for a turbine diaphragm segment is disclosed. The alignment member is configured to span radially across a portion of the turbine diaphragm segment and an adjacent turbine casing segment. The alignment member can include: a main body having a first aperture for aligning with a first corresponding aperture in one of the turbine diaphragm segment or the turbine casing segment; and a flange extending from the main body, the flange including a second aperture for aligning with a portion of the other of the turbine diaphragm segment or the turbine casing segment, the alignment member for adjusting a position of the turbine diaphragm segment relative to the adjacent turbine casing segment.

1. An alignment member for a turbine diaphragm segment, the alignment member configured to span radially across a portion of the turbine diaphragm segment and an adjacent turbine casing segment, the alignment member comprising: a main body having a first aperture for aligning with a first corresponding aperture in one of the turbine diaphragm segment or the turbine casing segment,wherein the main body aligns with the first corresponding aperture at a horizontal joint surface of the one of the turbine diaphragm segment or the turbine casing segment; anda flange extending from the main body, the flange including a second aperture for aligning with a portion of the other of the turbine diaphragm segment or the turbine casing segment,the alignment member for adjusting a position of the turbine diaphragm segment relative to the adjacent turbine casing segment. 2. The alignment member of claim 1, wherein a portion of the main body is configured to align flush with a portion of the turbine diaphragm segment proximate the first corresponding aperture at the horizontal joint surface. 3. The alignment member of claim 2, wherein the flange is configured to align spaced apart from a portion of the other of the turbine diaphragm segment or the turbine casing segment. 4. The alignment member of claim 1, wherein a portion of the alignment member proximate the first aperture is configured to align separated from a portion of the turbine diaphragm segment proximate the first corresponding aperture. 5. The alignment member of claim 4, wherein a portion of the alignment member proximate the second aperture is configured to align flush with a portion of the casing segment. 6. The alignment member of claim 1, wherein a surface of the flange is configured to align flush with one of the horizontal joint surface of the turbine diaphragm segment or the turbine casing segment. 7. The alignment member of claim 1, wherein the first corresponding aperture extends downward from the horizontal joint surface into the one of the turbine diaphragm segment or the turbine casing segment. 8. An alignment apparatus for a turbine diaphragm segment, the alignment apparatus comprising: an alignment member configured to span radially across a portion of the turbine diaphragm segment and an adjacent turbine casing segment, the alignment member including: a main body having a first aperture for aligning with a first corresponding aperture in the turbine diaphragm segment,wherein the main body aligns with the first corresponding aperture at a horizontal joint surface of the turbine diaphragm segment; anda flange extending from the main body, the flange including a second aperture for aligning with a portion of the turbine casing segment,the alignment member for adjusting a position of the turbine diaphragm segment relative to the adjacent turbine casing segment. 9. The alignment apparatus of claim 8, further comprising a first vertical alignment member operably connected with the first aperture. 10. The alignment apparatus of claim 9, further comprising a second vertical alignment member operably connected with the second aperture. 11. The alignment apparatus of claim 8, wherein the first corresponding aperture extends downward from the horizontal joint surface into the turbine diaphragm segment. 12. An alignment apparatus for a turbine diaphragm segment, the alignment apparatus comprising: an alignment lever member configured to span radially between the turbine diaphragm segment and a turbine casing segment, the alignment lever member operably affixed to a portion of the turbine casing segment and including: a main body; anda flange extending radially inward from the main body,the flange for engaging a portion of an upper diaphragm segment,the alignment lever member for modifying a position of the turbine diaphragm segment relative to the turbine casing segment; anda base member pivotably connected to the alignment lever member, the alignment lever member configured to pivot about a portion of the base member. 13. The alignment apparatus of claim 12, wherein the base member includes a pivot member and the alignment lever member is configured to pivot about the pivot member. 14. The alignment apparatus of claim 12, wherein the base member is further configured to fixedly connect to the turbine casing segment. 15. The alignment apparatus of claim 12, wherein the base member is further configured to fixedly connect to the main body of the alignment lever member. 16. The alignment apparatus of claim 12, wherein the main body is configured to pivotably connect with the base member. 17. The alignment apparatus of claim 12, wherein the flange remains substantially free when the main body is fixedly connected with the base member. 18. The alignment apparatus of claim 12, further comprising an adjustment screw for adjusting a position of the alignment lever member. 19. The alignment apparatus of claim 12, wherein the main body includes an aperture configured to align with an aperture of the turbine casing segment. 20. The alignment apparatus of claim 19, further comprising an attachment member for connecting the main body with the turbine casing segment at the aperture of the main body and the aperture of the turbine casing segment.
