Neutronic reactor burial assembly

Claim 1

A FIVE-PIECE, DOUBLE ENCLOSURE BURIAL ASSEMBLY FOR A NEUTRONIC REACTOR COMPRISING AN INNER COFFIN ENCLOSURE OF RADIATION-SHIELDING MATERIAL CONSISTING OF AN INVERTED CUP-SHAPED UPPER PORTION AND A SEMISPHERICAL LOWER PORTION, THE UPPER SURFACE OF THE LOWER PORTION ADAPTED TO ABUT THE UPPER PORTION AROUND AN ANNULAR AREA OF ITS UPPER PERIMETER AND TO SUPPORT A COMPLETE REACTOR CORE WITHIN THE CIRCULAR AREA ENCLOSED BY THE ANNULAR SURFACE, AN OUTER SHROUD ENCLOSURE CONSISTING OF A HEMISPHERICALLY SHAPED PLATE OVERLYING THE LOWER OUTER SURFACE OF SEMISPHERICAL PORTION OF THE COFFIC ENCLOSURE, A CYLINDRICAL SIDE PORTION WITH A SLOPED ANNULAR FLANGE AT ITS BOTTOM EDGE OVERLAPPING THE HEMISPHERICAL PLATE, AND AN ANNULAR PICK-UP HEAD, OF SUFFICIENTLY LARGE DIAMETER TO MAKE IT FIT SLIDABLY OVER THE CYLINDRICAL SIDE PORTION, SAID SIDE PORTION HAVING ON ITS INNER SURFACE ADJACENT ITS UPPER EDGE A PLURALITY OF SPACED HOOKS WITH EQUAL ARCUATE HORIZONTAL BEVELLED SURFACES FACING DOWNWARD, AND SAID PICK-UP HEAD HAVING A PERIPHERY PROVIDED WITH A SECOND EQUAL PLURALITY OF OUTWARDLY EXTENDING HOOKS WITH EQUAL ARCUATE HORIZONTAL BEVELLED EDGES FACING UPWARD, THE SPACES BETWEEN BOTH PLURALITIES OF HOOKS BEING SUFFICIENTLY LONGER ARCUATELY THAN THE ARCUATE SURFACES OF BOTH PLURALITIES TO PERMIT THE LOWERING OF THE UPWARDLY FACING PLURALITY OF HOOKS BELOW THE DOWNWARDLY FACING PLURALITY OF HOOKS, MEANS FOR HORIZONTALLY ROTATING THE UPWARDLY FACING PLURALITY OF HOOKS WHILE IN SUCH LOWERED POSITION TO MAKE THEIR UPWARDLY FACING SURFACES CONFRONT THE DOWNWARDLY FACING SURFACES OF THE PLURALITY OF HOOKS ATTACHED TO THE SIDE PORTION OF THE SHROUD ENCLOSURE, AND SET SCREWS THREADED THROUGH THE PICK-UP HEAD, WITH SUFFICIENT LENGTH TO EXERT, ON BEING TIGHTENED DOWNWARDLY, PRESSURE ON THE OUTER SURFACE OF THE INVERTED CUP-SHAPED PORTION OF THE INNER COFFIN ENCLOSURE, TO RAISE THE PICK-UP HEAD AND CREATE A GRIPPING PRESSURE BETWEEN THE CONFRONTING SURFACES OF THE TWO PLURALITIES OF HOOKS AND A DOWNWARD PRESSURE BETWEEN THE INVERTED CUPSHAPED PORTION OF THE INNER COFFIN AND THE ANNULAR AREA OF THE SEMISPHERICAL BOTTOM PORTION, AND BETWEEN THE HEMISPHERICAL PLATE OF THE OUTER SHROUD ENCLOSURE AND THE SLOPED ANNULAR FLANGE OF THE CYLINDRICAL SIDE PORTION, THEREBY CREATING A RIGID FIVE-PIECE, DOUBLE ENCLOSURE BURIAL ASSEMBLY ADAPTED TO BE RAISED AND TRANSPORTED AS A UNIT.
