Deuterium Processing & Intake (Deck 15)

The deuterium processing and intake facility in the engineering hull is a tall, cavernous space that rises through nearly two full deck heights, dominated by a cluster of massive vertical purification columns finished in matte grey-white composite and banded at intervals with dull bronze-gold structural rings. Each column stands nearly four meters tall, thick as a person's outstretched arms, and hums faintly with the deep resonant vibration of raw deuterium being cycled through successive filtration stages. Sections of the columns' outer casing are transparent viewing ports, and through them a faint blue-white luminescence is visible, the glow of processed fuel moving through the internal conduits before being routed onward. Overhead, a dense lattice of intake piping converges from the outer hull toward the columns, thick insulated trunks running at odd angles across the high ceiling before dropping down to feed each processing unit in turn. The pipes are cold to the touch and frequently beaded with condensation, a fine mist sometimes visible drifting from poorly sealed joints and dissipating quickly in the compartment's forced air circulation. The deck is grated metal in a broad walkway pattern around the columns' bases, allowing technicians to move freely for inspection while the deeper mechanical spaces below remain hidden beneath. A control alcove is recessed into one wall, housing a bank of LCARS monitoring stations that track intake flow rate, purification stage completion, and contamination levels for each column independently, the displays awash in shifting blues and greens that mirror the calm, steady hum of nominal operation. The air here carries a faint chemical coolness, tinged with the metallic tang particular to raw, unrefined deuterium, distinct from the cleaner smell of the fully processed fuel elsewhere on the ship. Lighting is utilitarian, angled floodlights mounted high on support struts that wash the columns in flat white light, leaving the upper reaches of the compartment in soft shadow. The overall impression is one of quiet, continuous industrial activity, the columns processing fuel in an unbroken rhythm marked only by the occasional soft clank of an intake valve cycling closed.
