1. A nozzle for a turbine system, the nozzle comprising:
an airfoil including a tip and a root; and
an endwall connected to the airfoil at one of the tip and the root, the endwall including:
a first side slash face at a first circumferential edge of the endwall;
a second side slash face at a second, opposing circumferential edge of the endwall from the first circumferential edge;
a seal pocket defined axially in each side slash face, wherein the seal pocket of each side slash face is configured to receive a seal positioned therein for spanning a gap between adjacent nozzles, each seal pocket having a first circumferential extent; and
an inner surface extending between the first and second side slash faces, the inner surface including a first planar surface portion adjacent to the first side slash face and a second planar surface portion adjacent to the second side slash face and an arcuate surface portion extending from and starting at the first planar surface portion to and stopping at the second planar surface portion, the arcuate surface portion being one of generally concave or generally convex, wherein the first planar surface portion and the second planar surface portion each extend circumferentially from and start at a respective circumferential edge of the respective side slash face, and wherein the first planar surface portion and the second planar surface portion each extend circumferentially to and stop at a circumferential location radially aligned with the first circumferential extent of each respective seal pocket at a single axial location.
