This document provides the constitutional instantiation of the EET framework in the domain of nuclear physics. The nucleus is constituted as a composite constraint network: the nucleon is a Type I constraint vertex (matter, Ec>0, m=Ec/v_², SU (2) spin and isospin graph connection indices, Particle v3. 3 2. 1) ; the nuclear force is the residual constraint coupling between color-neutral composite vertices in the QCD-congested (=J) regime --- the three components (central, tensor, spin-orbit) are three distinct Arrhenius excitation modes of Type II gluon edges on the constraint network; nuclear structure is the spectrum of the constraint network Laplacian L, with magic numbers emerging as spectral gaps (GT v3. 0 III. 2, CLOSED) and the liquid drop model as encapsulation boundary thermodynamics (HD v3. 2 III. 8) ; nuclear reactions are the five constraint operations (Formation, Meltdown, Maintenance, Transient Event, Capture) instantiated in the nuclear domain; nuclear thermodynamics is governed by the Five-Channel Complete Constraint Second Law (CND v4. 0 III-C. 2, CLOSED-in-EET) ; nucleosynthesis is a constraint formation chain driven by Arrhenius activation across all five channels. Five Core Constitutional Contributions. (1) Multi-Body Force Arrhenius Suppression. The systematic suppression of N-body nuclear forces (N3) is explained not by chiral effective field theory power-counting conventions, but by the Arrhenius exponential penalty e^-N300\, MeV/kB T₄₅₅ incurred by intermediate resonance excitations required for irreducible N-vertex connected subgraphs on the constraint network (NP-1). (2) Magic Numbers as Laplacian Spectral Gaps. Magic numbers (2, 8, 20, 28, 50, 82, 126) are not phenomenological inputs but constitutional outputs --- they occur at nucleon numbers A where the Laplacian spectral gap ₁ attains local maxima, a direct consequence of the Cauchy Interlacing Theorem (GT v3. 0 III. 4, CLOSED) applied to vertex addition on the constraint network (NP-4). (3) Fission Arrhenius Cascade --- Closed Constitutional Framework. The complete microscopic description of nuclear fission is provided by a self-consistent constitutional framework integrating five elements: Laplacian spectral evolution along the fission path (shell effects), dual-channel damping (dissipation: elastic 1-, plastic C (t) ), Coulomb repulsion (EM subnetwork interaction), five-channel entropy generation (thermodynamics, CLOSED), and constraint network path integral (CND v4. 0 II-A, CLOSED) for numerical computation --- requiring no phenomenological dissipation tensors (NP-23). (4) Reactor Antineutrino 5 MeV Bump --- Arrhenius Density of States. The anomalous excess of reactor antineutrinos at E₅--7 MeV is interpreted as a local enhancement of the Arrhenius Laplacian spectral density g () in fission fragment constraint networks, with the specific prediction that the bump amplitude is larger for ^239Pu than ^235U fission (NP-13). (5) Symmetry Energy Arrhenius Framework. The symmetry energy S () is expressed as the Arrhenius maintenance cost density-dependence of template-different vertices on the constraint network, providing a unified constitutional interpretation of the apparent tension between PREX-II (L10637 MeV) and GW170817 (prefers lower L) as different Arrhenius response regimes probed by different experimental observables (NP-9). Eleven Major Nuclear Physics Problems Constitutionally Resolved. The document integrates EET constitutional resolutions for the following problems directly into the body text: NP-1 (multi-body force Arrhenius suppression), NP-2 (repulsive core as constraint congestion topology), NP-4 (magic numbers as Laplacian spectral gaps), NP-5 (Hoyle state as -condensation Arrhenius resonance), NP-7 (r-process unified with s-process via Arrhenius cascade), NP-9 (neutron star EOS symmetry energy Arrhenius framework), NP-11 (constraint network as QCD-to-nuclear-physics constitutional relay layer), NP-13 (reactor antineutrino 5 MeV bump), NP-22 (proton spin crisis as encapsulation shell collective SU (2) connection), NP-23 (fission Arrhenius cascade closed constitutional framework), and NP-33 (color glass condensate as Arrhenius congestion saturation limit). Nineteen additional problems are registered in the Academic Priority Registration and Constitutional Open Problems sections. Cross-Domain Bridges. Thirty-one bridge declarations (28 mother-text + 3 cross-REAL bridges to EM REAL v1. 0) register the constitutional dependencies of all nuclear physics content on the upstream mother texts. The cross-REAL bridges establish the complementary relationship between the EM open subnetwork (J) and the nuclear congested subnetwork (=J) as two extremal regimes of the same constraint network constitutional framework.
