1 Dismantle & installation of 1. Introduction This Statement of work (SOW) describes the requirements for the services needed to refurbish the ( The System ) of the nuclear research reactor at the Instituto Nacional de Investigacion Nuclear (ININ), in its Nuclear Center "Dr. Nabor Carrillo Flores, located on the Mexico-Toluca Highway s/n, La Marquesa Ocoyoacac, Mexico, where the work will be performed. ININ has a nuclear reactor which has a that requires being refurbished. The IAEA plans to provide assistance to the Government of Mexico, in the framework of the technical cooperation project MEX2016, to modernize ININ s nuclear reactor The Contractor must note in their proposal any assumptions made. The selected Contractor shall work with ININ, the pump supplier, and the cooling tower supplier to deliver the complete system. 2. Scope of work Dismantle the present cooling tower and two motor pumps and install new ones of the same characteristics. Cooling tower and new pumps will be purchased by IAEA in separate contracts. The contractor shall perform the following services: 2.1 Disconnect all electrical components before dismantling and removal of the existing cooling tower, motor pumps and its components; 2.2 Dismantle and remove the existing cooling tower; 2.3 Dismantle and remove the motor pump P1 in the primary ; 2.4 Dismantle and remove the motor pump P2 in the secondary ; 2.5 Dismantle, remove from ININ premises and dispose of all obsolete equipment, obsolete pipes and obsolete electrical components connected to the existing cooling tower and motor pumps in the primary and secondary ; 2.6 Remove from the ININ premises, after obtaining clearance from ININ, and dispose of the dismantled cooling tower (contains asbestos) its debris and all the obsolete parts that were dismantled; 2.7 The dismantled motor pumps shall be handled to ININ personnel for storage and future use; 2.8 Clean and prepare the area to enable the future installation of the new cooling tower, motor pumps and its associated components, including as a minimum placement of supports for the cooling tower, civil works, painting and coating the area and construction of concrete slabs; 2.9 Transport the new cooling tower and motor pumps from the storage place, inside ININ s premises, to the erecting location; 2.10 Perform the mechanical and hydraulic installation of the new cooling tower, motor pumps and associated components and systems, including pipes, valves, fittings and other components as required; Page 1 of 6

2 2.11 Perform the electrical installation of the new cooling tower, motor pumps and associated components and systems: installation of electrical boards, electrical cables, control panels, wiring devices, electric motors, inverters and other components as required; 2.12 Perform the following complementary work in the cooling tower area: (see Annex 1): Construct a concrete slab or a metallic structure on top of the existing tank (5.5x5.5m) to support the new cooling tower The Contractor shall provide the electrical components associated to the cooling tower and pumps; and 2.14 The Contractor shall provide the mechanical and hydraulic components (valves, pipes and fittings) necessary to interconnect the motor pumps and the cooling tower. 3. Existing and parts to remove (Fig 1) The existing system is as follows: P1 P2 T1 FIG. 1: Schematic of 3.1 Primary motor pump (P1) with the following characteristics: 15 HP, 3600 RPM, 350 GPM, weight approx. 100 kg (see pictures at end of document). 3.2 Secondary system motor pump (P2) with the following characteristics: 40 HP,1800 RPM,700 GPM, weight approx.100 kg (see pictures at end of document). 3.3 Cooling tower T1 with the following characteristics: 700 GPM, the tower has an external asbestos covering and ceramic tiles in the interior, (see pictures at end of document, and Annex 1). 4. Deliverable Data Items The Contractor shall provide, to ININ, in the Spanish language: 4.1 Two weeks before starting the site works, a programme of activities, broken down by day. 4.2 Weekly progress reports including photos Page 2 of 6

3 4.3 The as-built engineering drawings, mechanical diagrams, electrical diagrams and layout of the new cooling tower, motor pumps and its associated components (pipes, parts and systems connected to the new cooling tower, new pumping equipment, etc.); Drawings and blue prints must be delivered in Autocad and two hard copies. 4.4 Certification from the supplier of correct installation of components (IQ). 4.5 Acceptance tests reports 4.6 A maintenance plan 5. Quality Requirements 5.1 The Parts shall be manufactured, shipped and installed in accordance with the Contractor s ISO quality assurance system or an equivalent quality assurance system. 5.2 The Service shall be provided in accordance with the Contractor s ISO quality assurance system or an equivalent quality assurance system. 5.3 The Contractor shall document the compliance with this quality assurance system. 5.4 The new shall meet USA Cooling Technology Institute (CTI) standards or equivalent standards applicable for s. 6. Verification of engineering, installation and supply of components, and functionality of the System 6.1 The detailed construction and erection plan must be approved by ININ before starting the construction and erection phase. 6.2 The acceptance tests of supplies and services will be carried out by the contractor immediately after the installation of all the supplies and the checking of its proper functioning. These tests consist of the verification of compliance of the technical and functional requirements of this technical specification and documents here mentioned. Protocols for the acceptance tests shall by approved in advance by ININ. 6.3 The results of the testing of the System shall be documented by the Contractor in an acceptance test report countersigned by the End-User (ININ). 6.4 The final (as built) System shall be approved by the End User upon completion. 6.5 Acceptance tests results shall be approved by IAEA at its satisfaction. 7. Delivery time The Contractor shall provide a timeline from Purchase Order to completion, and assuming supply of pumps and cooling tower within 8 weeks. Note that this timeline is important to the IAEA and will be taken into consideration by the IAEA in the evaluation of best value for money. The expectation is 14 (fourteen) weeks. 8. Other considerations The Contractor shall observe the following important considerations when presenting its proposal: Page 3 of 6
